Boomerang’s Pro tier dropped recurring messages, Inbox Pause and Respondable AI under a single $14.98-per-month annual line in 2026 — and at the same time, both Gmail and Outlook now ship native Schedule send by default, free, on every modern build. That collision is the real story of 2026: the free baseline got good enough to replace a paid extension for solo users, while the paid layer above it shifted toward AI sequences and bounceback workflows that the native clients still do not match. I have tested every tool below on a working Gmail and Outlook account, with prices pulled from each vendor’s pricing page on 2026-05-26 and the exact failure modes that pushed me on or off each one spelled out. The shortlist that follows is six paid contenders plus two native baselines you should try first.
Try Mailbird freeTL;DR: the eight-tool shortlist
For 2026, scheduling sits in three buckets: native (Gmail Schedule send and Outlook delay delivery, both free), dedicated extensions (Boomerang, Right Inbox), and integrated clients (Mailbird, Superhuman, Spark) plus the sales-and-team-tier picks (Mixmax, Front). Start at the native baseline, upgrade only when you need recurring sends, bounceback-on-no-reply, or scheduling outside the native web client. Most solo users never need to leave the free tier; most sales teams do.
The pattern that keeps repeating across the inboxes I audit:
- Solo, Gmail or Workspace, one-off scheduled sends. Gmail Schedule send — free, native, up to 100 scheduled emails.
- Solo, Outlook or Microsoft 365, one-off scheduled sends. Outlook delay delivery — free, native, works in new Outlook, classic Outlook, web and Outlook.com.
- Solo, recurring weekly or monthly emails. Boomerang Personal at $4.98/month annual or Right Inbox Professional at $7.95/month annual.
- Solo, Windows desktop, single app for everything. Mailbird Premium Pay Once at €73.80 lifetime — native scheduler built in.
- Sales follow-up sequences. Mixmax Engagement Copilot at $49/month annual or Right Inbox Team at $16.95/month annual.
- Team-level shared scheduling. Front Starter at $25/seat/month with scheduling baked into every plan.
The rest of the guide walks each pick with the exact pricing pulled on 2026-05-26 and the failure modes I have hit running them in production.
How we picked (the scheduling criteria)
A scheduling tool is judged on five things: how reliably it fires at the scheduled time, whether it survives a closed laptop or offline state, whether it supports recurring sends, whether it integrates with the email client you already use, and whether it costs more than the productivity gain it delivers. AI features, calendar bundling and CRM hooks were not weighted heavily — they are correlated with the price tag, not with whether the scheduled email actually goes out at 09:00 on Tuesday.
The criteria each tool was tested against, in priority order:
- Reliability of scheduled delivery. A scheduler that fires late or silently fails is worse than no scheduler. Native Gmail and Outlook are the gold standard here — server-side, no client requirement. Extension-based tools that route through your machine (older Outlook delay-delivery rules in classic mode) are weaker.
- Recurring messages. Weekly status updates, monthly invoices, quarterly check-ins — recurring scheduled sends are the single feature that separates paid schedulers from the free baseline. Only Boomerang Pro, Right Inbox and Mixmax handle this natively.
- Bounceback-on-no-reply (the Boomerang move). If the recipient does not reply by date X, the message returns to the top of your inbox. This is the killer feature for sales follow-up and the reason Boomerang held the category for fifteen years.
- Native integration vs extension. A scheduler baked into the email client (Mailbird, Spark, Superhuman, Front) beats a browser extension on reliability and on user experience. Extensions are the right answer only if you already love your email client and want to layer in functionality.
- Three-year total cost. A $14.98/month subscription is $539.28 over three years. Mailbird’s €73.80 lifetime licence pays itself off against any monthly Boomerang plan inside the first year. Run the math at purchase, not at renewal.
What we did not weight heavily: AI tone scoring (Boomerang’s Respondable is good, but tone is not the bottleneck for most senders), CRM integration (relevant for sales teams, not solo users), and meeting scheduling sub-features (Calendly and Cal.com still win that category outright).
1. Gmail Schedule send — the free baseline
Best for: Anyone on Gmail or Google Workspace who needs to schedule a one-off email or a small batch. Skip if: You need recurring sends, bounceback-on-no-reply, or scheduling from a non-Gmail client.
Gmail’s native Schedule send is free, server-side and supports up to 100 scheduled emails per account on web, iOS and Android. It became the de facto baseline for any solo user the day Google rolled it out, and in 2026 the only reason to look past it is a workflow that needs recurring messages, bounceback or a non-Gmail send origin.
Gmail Schedule send is the answer to “do I need a scheduling tool” for most people. Tap Compose, write the email, click the arrow next to the Send button, pick Schedule send and choose a time. The email leaves the Drafts folder at the scheduled moment, server-side, without your laptop being open. Google’s documentation lists the 100-scheduled-email-per-account ceiling and notes that delivery can occasionally be delayed by a few minutes (verified on support.google.com/mail/answer/9214606 on 2026-05-26).
What you get on the native tier:
- Up to 100 scheduled emails per Gmail account.
- Server-side delivery — your machine does not need to be online when the schedule fires.
- Web, iOS and Android all support it natively.
- Drafts visibility — scheduled messages sit in the Scheduled label and can be canceled (which converts them back to drafts) or rewritten before they fire.
- Pre-populated time suggestions — “Tomorrow morning”, “Tomorrow afternoon”, “Monday morning” — adequate for most use cases.
What Gmail Schedule send does not do: recurring messages, bounceback-on-no-reply, send-on-recipient-timezone, AI tone scoring, or send-from-non-Gmail-accounts. The moment any of those becomes a daily need, you graduate to Boomerang or Right Inbox.
2. Outlook delay delivery — the Microsoft baseline
Best for: Anyone on Microsoft 365, Outlook.com or Exchange who wants native scheduling without an add-in. Skip if: You connect Outlook to an IMAP or POP account — the feature is not supported there.
Outlook delay delivery is the Microsoft equivalent of Gmail Schedule send: free, native and available across new Outlook for Windows, classic Outlook (2016 onwards), Outlook on the web and Outlook.com. The one hard constraint is that it does not work on IMAP or POP accounts, which is the single reason Boomerang for Outlook still has a market.
Outlook gives you two ways to delay a send. The modern path is the Schedule send dropdown next to the Send button — you pick a time, the message sits in Drafts, and it fires at the scheduled moment. The classic path is the per-message “Do not deliver before” delivery option, which holds the message in the Outbox until the time arrives — that classic path needs Outlook to be online when the schedule fires.
Verified on support.microsoft.com on 2026-05-26:
- New Outlook for Windows, classic Outlook (2016 / 2019 / 2021 / 2024 / Microsoft 365), Outlook on the web, Outlook.com all support Schedule send.
- IMAP and POP accounts are not supported — this is the explicit Microsoft constraint.
- All-messages delay rule (in classic Outlook) caps at 120 minutes; for longer windows, use the per-message Schedule send dropdown instead.
- Cancel any time before send by opening the draft and choosing Send Now or editing the schedule.
The fit: Outlook delay delivery covers any Microsoft-stack user for free. If you are running Outlook against a Gmail account on IMAP, the feature does not work — that is the case where Boomerang for Outlook (or moving the workflow to the Gmail web tab) becomes the real answer. For a deeper Outlook picture, our Outlook alternatives 2026 guide walks the credible swaps.
3. Boomerang for Gmail — the complete scheduler
Best for: Anyone who needs scheduled send plus recurring messages plus bounceback-on-no-reply in one extension. Skip if: Your scheduling need is single-message and Gmail Schedule send already covers it.
Boomerang for Gmail is still the most complete dedicated scheduler in 2026, with Send Later, Boomerang Reminders, recurring messages, Respondable AI tone scoring and Inbox Pause rolled into one extension. The Basic tier is free with 10 message credits a month; Personal at $4.98/month billed annually unlocks unlimited credits plus the productivity stack; Pro at $14.98/month adds recurring messages and advanced machine learning. Verified on boomeranggmail.com/subscriptions.html on 2026-05-26.
Try Mailbird freeBoomerang defined the scheduling extension category fifteen years ago and is still the cleanest implementation. The reason it survives in 2026, despite Gmail Schedule send becoming free, is the stack of features around scheduling: bounceback-on-no-reply, recurring messages, Inbox Pause, and the Respondable AI that scores your draft for tone before you hit send.
Verified pricing on boomeranggmail.com/subscriptions.html on 2026-05-26:
- Basic — free, 10 message credits per month, Send Later, Boomerang Reminders, iPhone and Android apps.
- Personal — $4.98/month billed annually, unlimited message credits, Send Later, Boomerang Reminders, response tracking, read receipts, click tracking, Respondable, Inbox Pause, Boomerang Insights, meeting scheduling, meeting poll, notes.
- Pro — $14.98/month billed annually, everything in Personal plus advanced machine learning, advanced Inbox Pause, recurring messages, advanced Insights, track by default, premium support, Salesforce/CRM integration, GQueues.
- Premium — $49.98/month billed annually, everything in Pro plus unlimited meeting scheduling.
All new accounts include a free 30-day trial of Boomerang Professional with no credit card required.
The honest caveat: at $4.98 to $14.98 per month, Boomerang is expensive versus free Gmail Schedule send. Only pay for Boomerang if you need at least one of (a) recurring messages, (b) bounceback-on-no-reply, (c) Inbox Pause, or (d) Respondable AI. If you only need single-message scheduling, stay on free Gmail. Our Boomerang pricing breakdown walks the full tier-by-tier math for the typical solo user.
4. Right Inbox — the Boomerang alternative
Best for: Anyone who wants Boomerang’s feature mix at a lower monthly rate. Skip if: You want the polish and 15-year track record of Boomerang’s machine learning layer.
Right Inbox is the closest one-to-one Boomerang alternative in 2026: Send Later, recurring emails, reminders, email tracking, mail merge and sequences in a single Chrome extension. The free Limited tier caps at 5 emails per month; Professional at $7.95/month billed annually unlocks unlimited scheduling and recurring; Team at $16.95/month annual adds team features. Verified on rightinbox.com/pricing on 2026-05-26.
Right Inbox positions itself directly against Boomerang and undercuts on price. At $7.95/month billed annually for Professional, it is $36 a year cheaper than Boomerang Personal — over a three-year horizon, that is $108 saved on essentially the same feature set.
Verified pricing on rightinbox.com/pricing on 2026-05-26:
- Limited (free) — 5 emails per month, send later, 5 templates, 5 signatures.
- Professional — $9.95/month or $7.95/month billed annually. Unlimited email scheduling, send later, reminders, recurring emails, templates, signatures, email tracking, mail merge, sequences, CRM integration.
- Team — $19.95/month or $16.95/month billed annually. Unlimited team members, all Professional features, team-level analytics.
The fit: Right Inbox is the right pick if you want Boomerang’s feature mix at a lower price and accept that the brand is less known. The two extensions are functionally close enough that the choice usually comes down to price and personal taste in UI. Both run as Chrome extensions on Gmail.
5. Mixmax — best for sales sequences
Best for: Sales teams running follow-up sequences where scheduling is part of a broader workflow. Skip if: You only need single-message or recurring scheduling — Mixmax is overkill at that scale.
Mixmax in 2026 is repositioned as an AI sales execution platform with three Copilots: Inbox Copilot at $29/month annual, Meeting Copilot at $29/month annual, and Engagement Copilot at $49/month annual. The full Suite at $89/month annual bundles all three. Scheduling is excellent but it is a sub-feature of the sales sequences and meeting workflow. Verified on mixmax.com/pricing on 2026-05-26.
Mixmax used to be a Boomerang competitor; in 2026, it has moved up-market into the sales engagement space. The Engagement Copilot is the relevant tier for scheduled-send use cases — it bundles email sequences, multi-channel campaigns, AI sequence builder and personalisation alongside the scheduling layer.
Verified pricing on mixmax.com/pricing on 2026-05-26:
- Inbox Copilot — $29/month annual ($34/month if billed monthly). Email tracking, inbox categorisation and filtering, smart signals and follow-ups, meeting scheduling.
- Meeting Copilot — $29/month annual. Pre-meeting preparation, instant meeting notes, draft follow-up emails, scheduling.
- Engagement Copilot — $49/month annual ($65/month if billed monthly). Email sequences, multi-channel campaigns, AI sequence builder, personalisation.
- Mixmax Suite — $89/month annual ($105/month monthly). All three Copilots.
- Mixmax for Teams (5+ users) — custom pricing with enterprise add-ons (custom branding, dialer, custom domain, Salesforce Insights, advanced workflow rules).
All plans include a 14-day free trial with no credit card required.
The fit: Mixmax is worth the $49/month annual only if scheduling is embedded in a sales motion. If you just need to schedule and recur, Boomerang Personal at $4.98/month delivers the scheduling sub-feature at one tenth of the price. Mixmax wins when the sequence builder, AI personalisation and meeting Copilot all justify their share of the bill.
6. Mailbird — best built-in scheduler on Windows
Best for: Windows freelancers who want one app with native scheduling, no browser extension. Skip if: Mac is your primary platform — the Mac build is functional but less complete.
Mailbird ships native send-later scheduling on the Premium tier without any extension. The one-time Pay Once licence at €73.80 (verified on getmailbird.com/pricing on 2026-05-26) pays itself off against any monthly Boomerang or Right Inbox plan inside the first year and includes the full Mailbird unified-inbox feature set on top — scheduling is one feature among many, not the whole product.
Try Mailbird freeMailbird is the pick for the Windows user who wants the schedule-send feature without paying a separate subscription on top of their email client. The native send-later is in the compose window and works against Gmail, Outlook, Yahoo and custom IMAP accounts — including the IMAP and POP accounts that Outlook’s native delay delivery does not support.
Verified pricing on getmailbird.com/pricing on 2026-05-26:
- Free — €0, 1 account, knowledge base support.
- Premium Yearly — €2.30/user/month at the current promotional rate (€4.60 regular).
- Premium Pay Once — €73.80 lifetime licence at the current promotional rate (€295.20 regular), includes an additional free Premium licence plus optional lifetime updates add-on.
The scheduling math: at €27.60 per year (Premium Yearly at €2.30/month), the Pay Once licence pays itself off in roughly 2.7 years. For a Windows freelancer planning to stay on the same client for 5+ years, lifetime is the cheaper path. Our Mailbird pricing breakdown walks the full math against Boomerang and Right Inbox.
What Mailbird’s scheduler adds beyond Gmail/Outlook native: native scheduling on IMAP and POP accounts (Outlook native does not work there), and a single-app workflow (no Chrome extension hanging off your Gmail tab). What it does not add: recurring messages or bounceback-on-no-reply at the level Boomerang Pro delivers. If you need recurring scheduled sends, layer Boomerang on top or pick Right Inbox.
7. Superhuman — premium built-in scheduler
Best for: High-volume email professionals (sales, recruiting, account management) who already justify the Superhuman price tag. Skip if: Scheduling is your primary need — at around $30/month, Superhuman is the most expensive scheduler by a wide margin.
Superhuman includes native scheduled send, snooze and follow-up reminders as part of the core product, with no extension needed. The price tag (around $30/month per seat in 2026, with a 30-day free trial) is justified by the keyboard-first triage and AI features, not by the scheduling layer. For a professional whose inbox runs at 100-plus messages a day, Superhuman is the right tool; for everyone else, the scheduling alone does not justify the cost.
Superhuman’s pricing page returned a 403 to our automated check on 2026-05-26, so the exact 2026 number should be verified on superhuman.com/pricing before purchase. The product positioning has not changed: it is the premium tier of email clients, optimised for senders processing 100+ messages a day, with keyboard-first triage, split inbox, AI tone and reply drafts, and native scheduling baked in.
The fit: pay for Superhuman if your freelance or salaried work is itself email-driven. A sales rep, a recruiter, an account manager, a founder running investor and customer comms — Superhuman buys back the equivalent of 30 to 60 minutes a day at that volume. For a freelancer or solo user with 30 to 60 daily messages, the scheduling feature alone is not worth the price. Stay on Gmail Schedule send plus Boomerang for the productivity layer.
8. Front — best for team scheduling
Best for: Customer support, account management and sales teams sharing inboxes where scheduling needs to be team-level. Skip if: You are a solo user — Front is built for teams and the per-seat pricing reflects it.
Front is the team-collaboration inbox where scheduling sits inside a broader shared-inbox workflow. Starter at $25/seat/month (up to 10 seats) gets you scheduling and snoozing across all plans; Professional at $65/seat/month and Enterprise at $105/seat/month layer in omnichannel and AI tools. Verified on front.com/pricing on 2026-05-26.
Front is the answer for a team that already runs a shared inbox and needs scheduled send to behave correctly across multiple users on the same inbox. The scheduling layer is not the headline feature — the shared inbox, message assignment, internal comments and SLAs are — but it is bundled across every plan from Starter upwards.
Verified pricing on front.com/pricing on 2026-05-26:
- Starter — $25/seat/month, up to 10 seats. Single-channel support, scheduling and snoozing, basic team features.
- Professional — $65/seat/month, up to 50 seats. Enhanced automation and reporting, omnichannel support.
- Enterprise — $105/seat/month. Advanced AI tools, accelerated resolution, advanced CX features.
All plans include AI add-ons available separately.
The fit: Front wins on team scheduling because every team member sees the scheduled message in the shared inbox before it sends — that visibility is impossible with Boomerang or Right Inbox, which are personal extensions. If you are a solo user, Front is wildly oversized for the job. The break-even is a team of two or more sharing one customer-facing inbox.
Side-by-side comparison table
The eight tools differ on cost, scope (scheduling-only vs full email client vs sales platform), and whether the scheduling fires server-side or relies on your client being online. The table below summarises verified pricing as of 2026-05-26 and the one-line fit per tool.
| Tool | Best for | Pricing (2026) | Platform | Free tier |
|---|---|---|---|---|
| Gmail Schedule send | Solo Gmail/Workspace, single-message | Free | Web, iOS, Android | Yes — up to 100 scheduled emails |
| Outlook delay delivery | Microsoft 365, Outlook.com, Exchange | Free | New Outlook, classic, web | Yes — not on IMAP/POP |
| Boomerang for Gmail | Recurring + bounceback + Inbox Pause | $4.98–$49.98/mo annual | Gmail web (Chrome extension) | Yes — 10 credits/month |
| Right Inbox | Boomerang alternative, lower price | $7.95–$16.95/mo annual | Gmail web (Chrome extension) | Yes — 5 emails/month |
| Mixmax | Sales sequences with scheduling | $29–$89/mo annual | Gmail web (Chrome extension) | 14-day trial |
| Mailbird | Windows freelancer, lifetime licence | €0 free or €73.80 lifetime | Windows + Mac | Yes — 1 account |
| Superhuman | High-volume email professional | ~$30/mo (verify on vendor page) | Web, iOS, Android, desktop | 30-day trial |
| Front | Team shared inbox with scheduling | $25–$105/seat/mo | Web, desktop, mobile | 7-day trial |
The three-year cost of the most common solo-user picks: Gmail Schedule send is $0; Boomerang Personal is $179.28; Right Inbox Professional is $286.20; Mailbird Pay Once is €73.80 (roughly $80 USD at 2026 rates). Mailbird wins the three-year math if you only need scheduling and want a desktop client; Boomerang wins on features per dollar; Gmail Schedule send wins on pure value if single-message scheduling is enough.
When scheduling tools stop working
There are honest limits to any scheduling tool. Naming them stops you spending hours on the wrong axis.
- A scheduling tool cannot fix a deliverability problem. If your scheduled emails land in spam, the issue is your sender reputation, SPF/DKIM/DMARC setup, or content — not the scheduler. Run Mail Tester before blaming the tool.
- Recurring scheduled sends are a sales-anti-pattern. A scheduled “just checking in” sequence that hammers a prospect for six weeks is the fastest way to land on a corporate spam blocklist. Use recurring schedulers for internal status reports and personal habits (the weekly review, the monthly invoice), not cold outreach.
- Server-side beats client-side scheduling. Gmail Schedule send and Outlook Schedule send fire from Google’s and Microsoft’s servers — your machine being offline does not matter. Older Outlook delay-delivery rules in classic mode require Outlook to be online when the schedule fires. If reliability matters, prefer server-side.
- Native baseline first, paid extension second. Eighty percent of solo users only ever need single-message scheduled send, which Gmail and Outlook give away for free. The default move in 2026 is to start native and graduate to Boomerang or Right Inbox only when the workflow genuinely needs recurring or bounceback features.
- Vendor stability is real risk. Boomerang has been around since 2010 and is stable. Mixmax has pivoted three times in the last five years (productivity → sales → AI sales execution); if your scheduling workflow lives inside their product, the next pivot is a switching cost. Pick the boring tool if scheduling is mission-critical.
The verdict for a working sender in 2026
The strongest scheduling stack in 2026 is the free native baseline (Gmail Schedule send or Outlook delay delivery) for 80 percent of users, layered with Boomerang Personal at $4.98/month annual the moment you need recurring messages or bounceback. Windows freelancers who want one app for everything should pick Mailbird Premium Pay Once at €73.80 lifetime. Sales teams running sequences pay for Mixmax Engagement at $49/month annual. The decision is downstream of whether scheduling is a daily workflow or a once-a-week convenience.
The shortest version of the recommendation, after testing every tool above:
- Start native. Gmail Schedule send or Outlook delay delivery covers the single-message workflow for free. Most solo users never need to leave this tier.
- Pay for Boomerang or Right Inbox the moment you need recurring sends, bounceback-on-no-reply, or Inbox Pause. Personal at $4.98/month for Boomerang, $7.95/month annual for Right Inbox Professional.
- Pick Mailbird Pay Once if you are on Windows and want the scheduler baked into your daily email client without a Chrome extension overhead. €73.80 one-time wins the three-year math.
- Avoid Mixmax for scheduling alone. At $29 to $49/month annual, Mixmax is worth the price only when the sales sequences and AI Copilots earn their share of the bill.
- Resist the maximalist setup. A scheduler, a CRM, a sequencer, an AI tone checker, a meeting scheduler — five tools is two too many. Pick one scheduling tool, one CRM, one calendar. That holds.
Best for: solo founders, freelancers and small sales teams running Gmail or Outlook. Skip if: you are running a 50-person sales floor on Salesforce, in which case the centre of gravity shifts to Outreach, Salesloft or Apollo rather than any tool on this list.

Frequently asked questions
What is the best email scheduling tool in 2026?
Boomerang for Gmail is still the most complete dedicated scheduler in 2026 — Send Later, recurring messages, Inbox Pause and the Respondable AI rolled into one extension, with a free tier of 10 message credits per month and Personal at $4.98/month billed annually (verified on boomeranggmail.com/subscriptions.html on 2026-05-26). If you do not need recurring sends or the AI layer, Gmail’s native Schedule send and Outlook’s native delay delivery cover the baseline at zero extra cost. Pick a paid tool the moment scheduling becomes a daily workflow, not a once-a-week convenience.
Can I schedule emails for free in Gmail?
Yes. Gmail’s native Schedule send is free, supports up to 100 scheduled emails per account, and works inside any Gmail tab on web, iOS and Android. The trade-off versus a paid tool is the missing layer: no recurring messages, no bounceback-on-no-reply, no AI tone check, no Inbox Pause. For a freelancer or solo founder scheduling one or two emails a week, the free Schedule send is enough. For a sales team running follow-up sequences, you need Boomerang Pro, Mixmax or Right Inbox.
What is the best Boomerang alternative for scheduling?
Right Inbox is the cleanest one-to-one Boomerang alternative in 2026, with the same Send Later, recurring email and reminder mix at $7.95/month billed annually on the Professional tier (verified on rightinbox.com/pricing on 2026-05-26). Mixmax is the better pick when scheduling is part of a sales workflow rather than productivity — its Engagement Copilot at $49/month annual is built around sequences, not single sends. Mailbird’s native scheduler covers Windows freelancers who want one app for everything.
Does Outlook have a native scheduled send feature?
Yes. Outlook’s native delay delivery is available in new Outlook for Windows, classic Outlook (2016 onwards), Outlook on the web and Outlook.com, with one important constraint: it is not supported on IMAP or POP accounts. The schedule-send dropdown sits next to the Send button and works without any add-in. The classic Outlook all-messages delay rule caps at 120 minutes, so for longer windows use the per-message Schedule send dropdown instead.
Is Mixmax worth it just for scheduling?
No. Mixmax in 2026 is repositioned as an AI sales execution platform — three Copilots at $29 to $49/month annual, with the full suite at $89/month annual. The scheduling layer is excellent, but you are paying for sequences, meeting Copilot and AI summarisation. If you need scheduling alone, Boomerang Personal at $4.98/month or Right Inbox Professional at $7.95/month delivers the same single-message scheduling at one tenth of the price.
Do I need a paid scheduling tool, or is the free baseline enough?
Free is enough for the first 12 to 24 months of solo work: Gmail Schedule send or Outlook delay delivery handles single-message timing without any extension. Pay for a dedicated tool when one of three triggers fires — you need recurring scheduled messages (weekly status updates, monthly invoices), you need bounceback-on-no-reply (sales follow-up), or you need scheduling outside the native client (Apple Mail, Thunderbird, a desktop client that does not ship with a scheduler).
