How to Set Up Spark Email for Teams: Shared Inbox & Setup

Forwarding a support email to a colleague, then forwarding their reply back, then losing track of who answered what — that is the workflow Spark for Teams is built to kill. Readdle’s Spark layers shared inboxes, email assignments, shared drafts, and private comments on top of an ordinary email client, so a group can run one address together without a separate help desk. I set up a test team to walk the whole flow: creating the workspace, inviting members, wiring a shared inbox, and assigning a thread to a teammate. Here is the exact setup, what each tier costs, and where it fits.

What Spark for Teams Is and Who It’s For

Spark for Teams is Readdle’s collaboration layer on top of the Spark email client. It adds shared inboxes, email assignments, shared drafts, private comments, link sharing, and shared templates — so a group manages email together instead of forwarding messages around.

Spark started life as a personal email app and grew a team side. The team features turn a single address — support@, sales@, info@ — into something a group can run jointly, with everyone seeing the same messages and statuses. Per Readdle’s own description, shared inboxes let you “manage an inbox together with your team, assign emails and track their progress,” while team comments let you “chat privately in email threads.”

It fits two kinds of buyer. The first is a support, sales, or operations team drowning in forwards and CC chains who don’t want the weight of a full help-desk platform. The second is a small business that already lives in email and wants shared visibility on one mailbox without changing tools. If you’re evaluating Spark as a solo user first, our walkthrough on how to set up Spark email covers the single-account basics before you add a team on top.

Create a Team Workspace

Open Spark Settings, select Teams, and click ”+ Create New Team.” Name the team, choose which connected account it runs on, decide whether to auto-invite your whole company domain, and click Next. The team lives on your account and syncs across every device.

Creating the workspace is the first move, and it takes under a minute.

In Spark, open Settings, select Teams, and click ”+ Create New Team.” Following Readdle’s setup steps, you then enter the name of your team and, if you have several accounts connected, pick one under “Your email in this team.” There’s a checkbox that auto-invites everyone on your company domain — so anyone with name@yourcompany.com gets pulled in automatically. Leave it on for a company-wide team; disable the toggle if you want to invite only certain people. Click Next and the team exists.

Because the team is attached to your account rather than a device, it follows you everywhere you sign in. When I created my test team on a Mac, it was immediately present on the mobile app under the same login — no second setup.

Invite and Add Teammates

Go to Settings → Teams, choose your team, and click Manage Team. Open the Members tab, click Add members, and enter the email addresses you want to invite. They join once they accept and sign in. You add or remove members from this same tab anytime.

If you didn’t auto-invite a whole domain, you bring people in by hand — and it’s the same screen you’ll use to manage the roster later.

Head back into Settings → Teams, select the team, and click Manage Team. On the Team Preferences page, open the Members tab, click Add members, and type in the email addresses of the people you want. Each person gets an invitation and becomes active once they accept and sign in to Spark. Removing someone — when a contractor rolls off, say — happens from the exact same Members tab, so access stays tidy without an admin console.

Spark’s team tier is genuinely good, but it’s still tied to the Spark client. If your team would rather standardize on a single desktop app with built-in unified inboxes and a more traditional layout, Mailbird is worth a look on Windows — we compare the two head to head in our Mailbird vs Spark breakdown. Pick the one your team will actually open every morning; the best collaboration feature is the one people don’t avoid.

Set Up a Shared Inbox

A shared inbox lets several teammates manage one address — like support@ — simultaneously, all seeing the same messages, replies, and statuses. Shared inboxes are a Spark Pro feature. Connect the address to the team so everyone works it together instead of forwarding mail.

This is the centerpiece of Spark for Teams, and the reason most groups adopt it.

A shared inbox takes a single mailbox and opens it to the whole team at once: everyone reads the same incoming mail, sees each other’s replies, and tracks status in real time. Readdle positions it as the way to “manage an inbox together with your team, assign emails and track their progress” — no forwarding, no “did you see this?” pings. On the plans comparison, shared inboxes are listed as Unlimited on Pro and Enterprise, and they are not available on Free or Plus — so a shared support@ specifically requires Pro.

The practical win is that nothing falls through the cracks. When two people open the same mailbox, you need a way to stop double-replies and dropped threads — which is exactly what assignments are for, next. If you’re weighing Spark against a dedicated shared-inbox platform, Front is the obvious comparison; our breakdown of Front’s pricing shows where a purpose-built tool costs more than Spark’s bundled approach.

Assign an Email to a Teammate

Open the email and delegate it to a teammate so they own the reply — no forwarding, no shared password. The assigned person is named on the thread and everyone sees what’s still open. Plus includes 10 assignments per team; Pro and Enterprise make them unlimited.

A shared inbox without ownership is just a crowd staring at the same mail. Assignments fix that.

When a message needs one specific person, you assign — or delegate — it to them. Readdle describes delegation as a way to “assign responsibility for an email to another person” without forwarding the whole inbox or sharing a password. The named owner shows on the thread, so the rest of the team knows it’s handled and can see at a glance what’s still unowned.

The cap matters when you’re picking a tier. The plans comparison gives Plus “10 assignments per team” and makes them “Unlimited” on Pro and Enterprise. Ten total is fine to trial the workflow; a real support queue burns through that in a morning, which is another reason active teams land on Pro. Assignments are what turn a shared inbox from chaos into a tracked queue.

Shared Drafts and Private Comments

Invite a teammate into a shared draft to co-write or proofread a reply in real time, and use private comments to discuss a thread internally. Both stay hidden from the recipient — only the final email is sent. Shared drafts and comments are available from the Plus plan up.

The best teams catch problems before the email leaves, not after. These two features are how.

A shared draft lets you pull a colleague into a reply you’re composing so you both edit it live — Readdle frames it as inviting “teammates to compose email drafts in real-time.” Private comments sit alongside the thread for internal discussion; you can “chat privately in email threads” to debate the right answer, flag context, or ask “should we even reply to this?” The customer sees none of it. Only the finished message goes out.

Both land on the Plus tier and carry through Pro and Enterprise, per the plans comparison — so even the entry paid plan covers collaborative drafting. In my test team, the useful part was the order of operations: comment first to agree on tone, draft together second, send last. It removes the after-the-fact “sorry, ignore my last email” follow-up entirely.

Pricing, Platforms, and Admin Basics

Spark is free at €0, Plus is €10/month per user (€99/year), Pro is €22/month per user (€229/year), and Enterprise is custom. Shared inboxes need Pro; assignments and shared drafts start on Plus. Spark runs on Mac, Windows, iPhone, iPad, Android, and Apple Watch.

Tier choice comes down to one question: do you need a shared inbox or just assignments and shared drafts?

Per the Spark pricing page (accessed 2026-06-13), the Free Individual plan is €0. Plus is €10/month per user, or €8.25/month billed annually (€99/year), and includes shared drafts, private comments, 10 assignments per team, and 2 free active collaborators. Pro is €22/month per user, or €19.08/month billed annually (€229/year), and adds unlimited shared inboxes, unlimited assignments, shared templates, and unlimited collaborators. Enterprise is custom-priced with security controls and a dedicated success manager. (Confirm current figures on the vendor page before you buy — pricing changes.)

On platforms, Readdle lists Windows, Mac, iPhone, iPad, Android, and Apple Watch, and team settings sync across all of them because they live on your account, not the device — a genuine plus for mixed Mac/Windows teams. For admin, the same Settings → Teams → Manage Team screen handles members and team preferences; there’s no separate web console to learn. If you’re still comparing clients for a small or solo operation, our roundup of the best email apps for freelancers and our guide to setting up eM Client cover the alternatives worth a trial.

Verdict

To set up Spark for Teams: create a team in Settings → Teams, invite members from the Members tab, connect a shared inbox (Pro), then assign emails and use shared drafts and private comments to collaborate before sending. It’s a lightweight shared inbox built into an email app, not a full help desk.

Spark for Teams hits a sweet spot: real shared-inbox and assignment features without the cost or complexity of a dedicated platform. The setup is genuinely fast — team in a minute, members in two — and the collaboration layer (assign, draft together, comment privately) maps cleanly onto how a small team actually handles a shared mailbox. The one gating decision is the tier: a true shared inbox requires Pro, while assignments and drafts start on Plus.

Best for: small support, sales, or ops teams who want a shared inbox and email assignments inside a normal email app, across mixed Mac/Windows/mobile devices. Don’t bother if: you need full help-desk features — SLAs, CSAT, deep analytics, customer portals — in which case a purpose-built platform earns its higher price.

How do I create a team and invite people in Spark?

Open Spark Settings, select Teams, and click ”+ Create New Team,” then name the team and pick the account it runs on. To add people, go back into Settings → Teams, choose the team, click Manage Team, open the Members tab, click Add members, and enter their email addresses. If everyone shares a company domain, Spark can auto-invite the whole domain — leave that toggle on for a company-wide team or turn it off to invite only certain people. Members join once they accept and sign in.

What is the difference between a shared inbox and delegating an email in Spark?

A shared inbox is a single email address (like support@) that several teammates manage together — everyone sees the same incoming mail, replies, and statuses in real time. Delegating, or assigning, an email is narrower: you hand responsibility for one specific message to one named teammate so they own the reply. You use a shared inbox to give a group standing access to an address, and assignments to make sure each individual conversation has a clear owner. Shared inboxes are a Pro feature; assignments start on Plus, capped at 10 per team.

Does Spark for Teams work on Windows and Android, not just Mac?

Yes. Spark runs on Windows, Mac, iPhone, iPad, Android, and Apple Watch, and team settings sync across all of them because they live on your account, not the device. So a shared inbox you set up on a Mac is available to a teammate on Windows or Android, and an assignment made on a phone shows up on everyone’s desktop. Mixed-platform teams are a normal use case, not an exception.

Do shared drafts and private comments stay hidden from the customer?

Yes. Private comments and shared drafts are internal to your team — the recipient never sees them. You can discuss a thread, debate the right answer, and co-write or proofread a reply together, and only the finished email is sent out. That separation is the whole point: it lets a team align on tone and catch errors before the message leaves, rather than sending a fix-up follow-up afterward. The customer only ever receives the final, agreed reply.
