Install Connect accounts Inbox tabs & splits Shortcuts Licensing Updates Support

Install & activate

Download the latest DMG, open it, and drag Mailwell to Applications. The app is signed and notarized by Apple — it opens without warnings.
Launch Mailwell. On first run you'll see the activation screen.
No key yet? Start Free Trial takes you to checkout — your license key is emailed instantly and the first week is free.
Paste the key. Done — one license covers every account, on up to 3 of your Macs.

Connect your accounts

Add accounts from the sidebar's account list or Settings → Accounts → Add Account. Mix as many as you like into one unified inbox.

Microsoft 365 / Outlook

Click Sign in with Microsoft — your browser opens, you sign in, done. (Some workplace tenants show a short code to enter instead; both paths end in the same place.) Mail, folders, calendar invites, contacts, and server-side rules all work.

Gmail

Click Sign in with Google, or connect via IMAP with an app password (Google Account → Security → 2-Step Verification → App passwords).

Fastmail (JMAP)

Mailwell speaks native JMAP, Fastmail's own protocol — faster sync and instant push. On Fastmail: Settings → Privacy & Security → Integrations → New API token with Mail read/write, then paste the token into the JMAP tab. Other JMAP providers work the same way.

iCloud

Use the iCloud preset in the IMAP tab with an app-specific password from account.apple.com → Sign-In and Security → App-Specific Passwords. Username is your full Apple ID email.

Yahoo & AOL

Use the presets in the IMAP tab; both need an app password generated from their account-security pages.

Anything else

Any standard IMAP/SMTP server works — enter the hostnames and credentials in the IMAP tab.

Inbox tabs & splits

Every inbox gets Gmail-style tabs — Primary / Social / Promos / Updates — classified locally on every provider, so they work on M365 and IMAP too. Add your own custom splits in Settings → General → Custom Splits: extra tabs filed by sender, like @yourcompany.com, github, or a specific address. Splits sit between Primary and Social, matching mail leaves the other tabs, and ⇥ cycles through all of them.

Licensing

One license covers all your email accounts on up to 3 Macs.
Your key is on your purchase receipt and in your Gumroad Library.
Moving to a new Mac? Just activate there. Retiring one? Settings → License → Deactivate on This Mac.
Hit the activation limit after getting rid of an old machine? Activation frees a slot automatically — and if anything's ever stuck, email hello@mailwell.app.
7-day free trial at checkout — cancel during the trial and you pay nothing.
Manage or cancel your subscription any time from your Gumroad Library. After cancelling, the app keeps working until the end of the period you've paid for.

Privacy note: license checks send only your key to Gumroad (the payment processor). Your mail is never involved — Mailwell has no servers of its own.

Updates

Mailwell updates itself: when a new version ships you'll see a quiet prompt, and one click installs it. You can also check manually via Mailwell → Check for Updates… Every update is signed and notarized.

Support

Email hello@mailwell.app — bug reports, feature requests, and licensing questions are all welcome, and every message gets a reply.
