Spark by Readdle quietly rewrote its pricing in 2026. The old “Premium” personal tier is gone, replaced by a four-step ladder: Free, Plus at €10/month per user, Pro at €22/month per user, and Enterprise on quote. The team and personal tiers now share the same per-user prices, which makes the comparison cleaner but also makes Spark noticeably more expensive than the €4.99/month people remember from the previous price card. I ran Spark’s free plan myself, then pulled the live rates from sparkmailapp.com/pricing on 2026-05-23, and worked through what a solo user, a small team of three, and a ten-seat business each actually pay in 2026, where the AI quota bites, and who should pick a different client.
TL;DR: Which Spark Plan Fits You
Spark’s 2026 pricing has four tiers: Free at €0, Plus at €10/month per user (€8.25/month on annual billing), Pro at €22/month per user (€19.08/month annually), and Enterprise on quote. Free covers unlimited accounts and Smart Inbox but only previews AI. Plus adds full AI plus 40 meeting notes a month and two team seats. Pro adds unlimited AI meeting notes, unlimited collaborators, and HubSpot.
| Setup | Best plan | Annual cost (annual billing) |
|---|---|---|
| One user, no AI need | Free | €0 |
| One user, full AI | Plus (€8.25/month) | €120/year |
| Small team, 3 seats | Plus x 3 (€8.25/month each) | €360/year |
| Team, 10 seats with HubSpot | Pro x 10 (€19.08/month each) | €2 640/year |
Prices below are Spark’s published rates from the live pricing page. Monthly billing costs €10 (Plus) and €22 (Pro) per user; annual billing is €120 and €264 per year respectively. All figures verified on sparkmailapp.com/pricing on 2026-05-23.
What Spark Is, and What You Are Paying For
Spark is a cross-platform email client made by Readdle, the Ukrainian software studio that also built PDF Expert and Documents. It runs natively on Windows, Mac, iOS, iPadOS, Android, and Apple Watch. You are paying for AI features, team collaboration, custom templates, and productivity integrations on top of a free unified inbox.
Spark is not an email host. Your mailboxes still live at Gmail, iCloud, Outlook, Yahoo, or any IMAP provider; Spark is the client you use to read and send through those accounts. That changes what the subscription pays for. Unlike Fastmail, you are not buying storage or a custom domain. You are buying the layer on top of your existing mailboxes.
What every paid Spark subscription buys, across Plus, Pro, and Enterprise:
- Spark +AI: a writing assistant for drafting and rewriting replies inside the compose window.
- AI meeting notes: 40 per month on Plus, unlimited on Pro, transcribing and summarising calls that pass through your connected calendar.
- Custom templates: reusable snippets and full message templates, with team-wide sharing on Plus and above.
- Productivity integrations: Todoist, Notion, and Reminders out of the box; HubSpot specifically on Pro.
- Team collaboration: shared inbox, team comments, shared drafts, and assignments, with seat counts that scale by tier.
- Cross-platform sync: snooze, pin, and set-aside states travel across Windows, Mac, iOS, and Android in real time.
The structural thing to grasp before you compare line items: Spark in 2026 charges per user, not per household or per family. There is no Family plan, no Duo plan, and no shared-account tier. If two people want full AI, that is two Plus seats, not one.
The Free Plan: What You Actually Get
Spark Free costs €0 and includes unlimited email accounts, Smart Inbox, unified inbox, smart search, smart notifications, snooze, set aside, and calendar connections. Free users get a limited preview of Spark +AI via the AI Assistant and cannot purchase top-ups once the quota is used. Custom templates, integrations, and team features are paid-only.
I ran Spark’s free plan myself for a week on Windows and iOS against three connected accounts (Gmail, Outlook, IMAP). The honest read on what works and what does not:
What Free actually delivers:
- Unlimited email accounts: no cap, no upcharge for the fifth or tenth mailbox.
- Smart Inbox: the Pinned/Other split that separates real correspondence from newsletters and notifications.
- Unified inbox: a single feed across every connected account.
- Smart search: keyword filtering across all accounts at once.
- Smart notifications: only the messages Spark classifies as priority push a notification.
- Snooze and Set Aside: defer messages to a later time, or move them out of the inbox without archiving.
- Calendar connections: connect Google or iCloud calendars, view meetings alongside email.
What Free does not deliver:
- Full Spark +AI access: the AI Assistant gives you a preview, then stops. You cannot buy top-ups on Free.
- AI meeting notes: zero. Plus gets 40 per month, Pro gets unlimited.
- Custom templates: paid-only from Plus upward.
- Productivity integrations: Todoist, Notion, Reminders, HubSpot are all paid.
- Team collaboration: no shared inbox, no team comments, no assignments.
The free plan is genuinely usable as a personal mail client, which is uncommon at this end of the market. If your only ask is a better front end on Gmail and an iPhone app that talks to the same inbox, Free is the entire answer and you do not need to pay Spark anything.
Plus Plan (€10/month): The Personal AI Tier
Spark Plus costs €10/month per user on monthly billing or €120/year on annual billing, which works out to €8.25/month, about a 13 percent saving. It unlocks Spark +AI with the writing assistant, 40 AI meeting notes per month, custom templates, productivity integrations such as Todoist, Notion, and Reminders, and entry-level team collaboration with two free collaborators.
Plus is the plan most paying solo users will land on. The €10/month price is a real step up from the €4.99/month Spark Premium that older comparisons reference, and the rename reflects a fuller bundle: AI features that used to be ad-on are now folded in, and a small team allowance is part of the personal tier.
What Plus adds on top of Free:
- Spark +AI writing assistant: draft and rewrite replies, with tone controls inside the compose window.
- 40 AI meeting notes per month: automatic transcription and summary of calls on connected calendars.
- AI Assistant with full quota: no preview ceiling on day-to-day AI use within fair-use limits.
- Custom templates: reusable replies and full message templates, savable per user.
- Productivity integrations: Todoist, Notion, and Reminders connectors for turning email into tasks or notes.
- Two free collaborators: a small team allowance for shared drafts and team comments without jumping to Pro.
The 40-meeting-notes ceiling is the line to sanity-check. If you take more than two calls per business day on a connected calendar and want every one transcribed, you will hit the cap in the second half of the month and need to choose meetings to summarise manually. For most solo knowledge workers, 40 is comfortable; for sales reps in back-to-back calls, it is tight.
For storage, custom domains, and the underlying mailbox itself, Plus changes nothing: those still come from your email host. If you are choosing between paying Spark for a better client and paying Fastmail for a better mailbox, those are different products with different value propositions, not direct substitutes.
Try Mailbird freePro Plan (€22/month): The Team Tier
Spark Pro costs €22/month per user on monthly billing or €264/year on annual billing, around €19.08/month annually, a 13 percent discount on monthly. It includes everything in Plus plus unlimited AI meeting notes, unlimited collaborators, unlimited team assignments, 10 GB of team file storage per member, the HubSpot integration, read statuses, and Spark CLI with triage access.
Pro is the plan where the team-collaboration story stops being a token allowance and starts being a real feature set. The 2026 pricing tied this to per-user billing rather than a separate Teams tier, which simplifies the comparison but pushes the per-seat price well above what individual users typically expect to pay for an email client.
What Pro adds on top of Plus:
- Unlimited AI meeting notes: no 40-per-month cap.
- Unlimited collaborators: every seat counts as a full team member.
- Unlimited team assignments: assign any email to any seat with status tracking (open, in progress, resolved).
- 10 GB team file storage per member: pooled storage for attachments and shared assets.
- HubSpot integration: native two-way sync with HubSpot contacts and deals.
- Read statuses: see whether teammates have opened a shared email.
- Spark CLI with triage access: a command-line tool for bulk triage and scripted workflows.
Two things to weigh before picking Pro for a team:
- Per-seat math is unforgiving. Ten seats on Pro annually is €2 640/year. A purpose-built shared-inbox tool like Front or Missive is in the same price bracket; Spark Pro is competing on AI plus client quality rather than undercutting them.
- HubSpot is the gating integration. If your team already runs HubSpot as the CRM, Pro’s native integration is a concrete reason to choose it over Plus. If you do not use HubSpot, Plus with two free collaborators may cover small-team needs at less than half the price.
For storage and infrastructure outside the team workflow, Pro still does not change your underlying mailbox. The team file storage is for attachments and shared assets handled inside Spark, not a Dropbox replacement.
Enterprise: When You Need a Quote
Spark Enterprise pricing is custom and only available by contacting Readdle’s sales team. The tier adds security controls, SOC II compliance, a dedicated success manager, and 1:1 productivity coaching on top of everything in Pro. There is no published rate card.
Enterprise exists for the cases where Pro is functionally enough but the buyer needs procurement-grade contracts. The features that justify a sales conversation:
- Advanced security controls: SSO, audit logs, and admin-level access management.
- SOC II compliance: documented controls for regulated buyers.
- Dedicated success manager: a named contact for rollout and ongoing support.
- 1:1 productivity coaching: bespoke onboarding for executives or specialised teams.
If your buying process involves a security questionnaire, vendor risk assessment, or DPA negotiation, Enterprise is the route. If your team is under fifty seats and procurement is light, Pro at €19.08/user/month annually is likely the better fit and gets you the same product.
Monthly vs Annual: The 13% Discount
Spark’s annual billing saves about 13 percent against monthly on both Plus and Pro. Plus drops from €10/month monthly to €8.25/month on annual billing (€120/year). Pro drops from €22/month monthly to €19.08/month annually (€264/year). The percentage is identical across both tiers, with no multi-year discount published.
The annual discount is straightforward and consistent. The numbers:
| Plan | Monthly | Annual | Effective per-month | Annual saving |
|---|---|---|---|---|
| Free | €0 | €0 | €0 | n/a |
| Plus | €10/mo | €120/yr | €8.25/mo | ~13% |
| Pro | €22/mo | €264/yr | €19.08/mo | ~13% |
| Enterprise | Custom | Custom | Custom | Custom |
Spark does not publish a 24-month or 36-month rate the way Fastmail does. If you commit, you commit for one year at a time. That keeps the lock-in moderate: a year is short enough that you can switch clients without losing much if Spark raises prices again or kills a feature.
The practical advice: if you are confident Spark fits your workflow after a month on Free, take the annual rate. The 13 percent saving on Plus is €21/year and on Pro is €36/year per seat, which compounds quickly across a team. If you are uncertain, monthly costs €1.75/month more on Plus, which is a reasonable insurance premium for the right to cancel any time.
Cost Math: What Each Setup Actually Pays
On annual billing, a Spark Plus user pays €120/year per seat, and a Pro user pays €264/year per seat. A three-person team on Plus runs €360/year; the same team on Pro runs €792/year. A ten-seat team on Pro runs €2 640/year. Free is €0 for as many users as you connect, with no AI quota beyond the preview.
Because Spark prices per user with no household tier, the math is linear and the comparison with per-mailbox services like Fastmail is direct: Spark scales by headcount, not by mailbox count per person. Annual costs at the published rates:
| Setup | Plan | Per-seat annual | Total annual |
|---|---|---|---|
| 1 user, basic mail only | Free | €0 | €0 |
| 1 user, full AI | Plus | €120 | €120 |
| 3 users, Plus | Plus x 3 | €120 | €360 |
| 5 users, Plus | Plus x 5 | €120 | €600 |
| 10 users, Pro with HubSpot | Pro x 10 | €264 | €2 640 |
The single most useful number is the Plus-to-Pro step per seat: €144 more per user per year buys unlimited meeting notes, unlimited collaborators, HubSpot, and 10 GB file storage. For a five-person team that is €720 extra per year, real money for what is largely an AI quota lift and one CRM connector. Do the count of how many meetings your team actually wants transcribed before deciding Pro is worth the gap.
For comparison, a single mailbox on Fastmail’s pricing Individual plan is €60/year, and a Tutanota mailbox Revolutionary plan is €36/year. Those are mailbox subscriptions, not client subscriptions: they include the mailbox itself, the storage, and the custom domain. Spark Plus at €120/year is on top of whatever your underlying mail provider charges.
Who Should Skip Spark
Skip Spark if you want a one-time license rather than a recurring subscription, if you live in a Windows-only workflow with heavy multi-tool integrations beyond what Spark offers, or if cloud AI processing of your mail is unacceptable. Spark is a subscription-only cross-platform client with server-side AI; it does not compete on lifetime pricing and does not run AI locally.
Spark’s value is specific: a polished cross-platform client with strong AI and a generous free tier. That focus is a strength, but it makes Spark wrong for several use cases.
Skip Spark, specifically, if:
- You want a one-time lifetime license. Spark is subscription-only. If owning your client outright matters to you, Mailbird offers a lifetime license for Windows that costs less over five years than a single Plus seat does in two.
- You are Windows-only and the integrations dock matters. Spark integrates with Todoist, Notion, Reminders, and HubSpot but does not have a persistent always-visible side dock for Slack, WhatsApp, Google Calendar, and similar tools the way Mailbird does. For Windows desktop power users built around that workflow, Mailbird is the more natural fit. The best email clients for Windows 2026 guide compares the alternatives in detail.
- Cloud AI processing of your mail is a hard no. Spark’s AI features run on Readdle infrastructure, not on your device. If your work requires that no email content leaves your machine for AI processing, Spark’s Plus and Pro features are off the table.
One thing Spark does not fix on its own: a cluttered inbox full of newsletters. Smart Inbox bundles them into “Other,” but the subscriptions are still there. If your real problem is subscription noise rather than the client itself, the best unsubscribe tools 2026 guide covers the tools that clear that out, and they work whether your front end is Spark, Mailbird, or the native Gmail web client.
Verdict
Spark’s 2026 pricing is honest and a meaningful step up from prior years: Free is genuinely usable, Plus at €120/year per seat is fair for what you get if AI matters to you, and Pro at €264/year per seat is competitive for small teams that need HubSpot and unlimited meeting notes. Spark wins for anyone who wants a polished cross-platform client with native AI. It loses for users who want a lifetime license, an integrations dock, or guaranteed on-device AI.
Best for one user, basic mail only: Free at €0. Unlimited accounts, Smart Inbox, calendar connections, snooze, and unified inbox. No reason to pay if AI is not on your wishlist.
Best for one user with full AI: Plus at €8.25/month annually (€120/year). Spark +AI, 40 AI meeting notes per month, custom templates, and productivity integrations. The practical floor for paid Spark.
Best for a small team: Plus seats with the two-collaborator allowance if your team is two or three; Pro at €19.08/user/month annually (€264/year per seat) once you cross five seats or need HubSpot.
Best for an enterprise rollout: Enterprise on quote. Same product as Pro plus SOC II, SSO, audit logs, and a dedicated success manager.
Skip Spark if: you want a one-time license (look at Mailbird), your Windows workflow depends on the integrations dock (Mailbird again), or no email content is allowed to leave your device for AI processing (Thunderbird or another local-only client).

Frequently Asked Questions
How much does Spark email cost in 2026?
Spark has a free Personal plan at €0, a Plus plan at €10/month per user (€120/year, which works out to €8.25/month on annual billing), and a Pro plan at €22/month per user (€264/year, €19.08/month annually). Enterprise pricing is on quote. These rates are taken from sparkmailapp.com/pricing as of May 2026.
Is Spark email really free?
Yes, Spark has a genuinely free Personal plan with unlimited email accounts, Smart Inbox, smart notifications, snooze, set aside, calendar connections, and unified inbox. The catch is AI: free users get a limited preview of Spark +AI through the AI Assistant and cannot buy top-ups once the quota is used. Custom templates, integrations, and team features are paid-only.
What does Spark Premium include?
Spark’s paid Personal tier in 2026 is called Plus, not Premium. Plus costs €10/month per user (or €120/year on annual billing) and unlocks Spark +AI with the writing assistant, 40 AI meeting notes per month, custom templates, productivity integrations such as Todoist, Notion, and Reminders, and entry-level team collaboration with two free collaborators.
How much do Spark Teams plans cost?
Spark folds team features into the same per-user pricing as Personal plans in 2026. Plus at €10/month per user adds shared drafts, team comments, shared templates and two free collaborators. Pro at €22/month per user adds unlimited collaborators, unlimited team assignments, 10 GB of team file storage per member, and the HubSpot integration. Enterprise is custom-priced.
Is there a Spark free trial for paid plans?
Spark’s Free plan acts as the open-ended trial of the core product, including unlimited accounts and Smart Inbox. Paid AI usage on Plus and Pro is gated by the quota itself, with the limited Spark +AI preview on Free giving you a taste before you commit. There is no separate fixed-length trial advertised on the public pricing page.
Can you pay monthly or only annually for Spark?
Both. Spark Plus is €10/month on monthly billing or €120/year on annual billing, which is €8.25 per month, roughly a 13 percent saving. Spark Pro is €22/month on monthly billing or €264/year on annual billing, around €19.08 per month, again about 13 percent off. The discount is identical in percentage terms across the personal paid tiers.
Who should skip Spark and pick a different email client?
Skip Spark if you want a one-time license rather than a subscription, if you live in a Windows-only workflow with heavy multi-tool integrations, or if cloud AI processing of your mail is a non-starter. Mailbird is the natural alternative for Windows desktop power users who want a lifetime license and an integrations dock; Thunderbird is the answer for privacy-first users who refuse server-side processing.
