MailMaster connects Gmail, Outlook, Apple Mail, Yahoo, iCloud — and every inbox you have — in one clean desktop app. AI reads your emails, surfaces what's urgent, and sends follow-ups automatically. Your email stays where it is. The chaos doesn't.
Built for professionals who live in their inbox every day
One app. Every inbox. Gmail, Outlook, Apple Mail, Yahoo, iCloud — and any IMAP account. Nothing changes, nothing migrates. You just get a smarter way to manage it all.
Your emails stay exactly where they are. MailMaster connects to your existing Gmail, Outlook, or any IMAP account via secure OAuth. Nothing moves, nothing changes — you just get a smarter way to manage everything. Connect in 30 seconds.
You already use Gmail, Outlook, or Apple Mail. MailMaster sits on top — connecting all your inboxes, reading them with AI, and doing the work your email platform was never designed to do.
MailMaster connects every inbox you have and adds the layer Gmail and Outlook were never designed to give you — intelligent triage, automated follow-ups, AI-drafted replies. Keep your accounts. Upgrade how you use them.
Every morning MailMaster reads your entire inbox and gives you the 6 emails that actually need you — hot leads, client decisions, revenue at risk. The other 241? They wait until you're ready.
Set a rule: "No reply in 3 days — send this." MailMaster sends follow-ups from your real email address, stops the moment they reply, and logs the result. Warm leads don't die in your draft folder anymore.
Click once. AI reads the full thread and writes a contextual reply in your tone — with the right context, the right ask, the right close. Review it, tweak it, or send it straight. Thirty seconds to clear an email that would have taken 10 minutes.
Open a 40-email client thread and get the full picture in 3 lines: what was decided, who's waiting, what you need to do. You stop reading email chains and start acting on decisions.
Connect Gmail, Outlook, client inboxes, custom domains — all in one app. View everything in a single Priority feed or switch accounts in one click. Stop living in browser tabs.
Open tracking, read receipts, AI-recommended send times, reply rate analytics. Stop guessing who saw your proposal. MailMaster tells you exactly who opened what — and when to follow up.
Agency owners and SaaS founders lose deals every week not because the prospect wasn't interested — but because the follow-up came 6 days late. MailMaster sends it on day 3, from your real email address, in your voice. The prospect replies to you. You step in at exactly the right moment.
No learning curve. No migration. No configuration beyond connecting your existing accounts. If you've used Gmail, you already know MailMaster.
Native desktop app for Mac or Windows. Installs like any other app. No browser, no extensions, no configuration to touch.
Authorize Gmail or Outlook via OAuth — no passwords stored anywhere. Add all your accounts: client inboxes, personal, business. Basic: 5 accounts. Premium: unlimited.
MailMaster scans your email history to learn who matters, what's urgent, and what can wait. Builds your personal priority model. You watch it happen in real time.
Open MailMaster on Monday morning. 6 emails that need you — everything else ranked, summarised, handled. Most users reclaim 90 minutes their very first day.
These aren't MailMaster claims. They're published findings from the world's largest research organisations — and they describe your working day exactly.
The average professional spends 2.6 hours per day managing email — nearly a third of every working day. That is 650 hours a year on something that shouldn't take more than 20 minutes.
Of sales professionals give up after just one follow-up. Yet 80% of deals close only after 5+ touchpoints. Every silent inbox is a pipeline leak.
More likely to qualify a lead when you respond within 5 minutes vs 30. After an hour, probability drops 400%. Speed wins deals — but only if you see the email first.

No subscriptions. No usage limits. No surprises. Superhuman costs $360/year — forever. MailMaster is $199 one time during early access. Most users recoup the price in their first week.

Yes — MailMaster is a full email client. You send, receive, organise, and reply to emails entirely within MailMaster. You don't need to open Gmail or Outlook at all. It connects to your accounts via OAuth, so your emails still live in Gmail/Outlook's servers, but you manage everything through MailMaster's interface.
Gmail (Google OAuth), Outlook / Microsoft 365 (Microsoft OAuth), Apple Mail, ProtonMail, Yahoo Mail, Zoho Mail, Fastmail, and any email service via IMAP/SMTP. Basic connects up to 5 accounts. Premium connects unlimited accounts.
During setup (about 2 minutes), MailMaster AI analyses your email history — who you reply to, how fast, which threads you open first. It builds a priority model personalised to you. Over time it gets smarter as you use it. You can also manually tag contacts as high-priority.
One-time payment. $199 for Basic, $299 for Premium during early access — going up to $349/$479 after launch. Pay once, use forever. No monthly fees, no usage limits, no surprises. A 3-month installment option is also available at checkout.
Yes. Your email credentials and settings are encrypted and stored only on your device — never on MailMaster's servers. Your emails themselves stay on your email provider's servers (Gmail, Outlook, etc.) as normal. When AI features process an email — to summarise it or draft a reply — the content is processed in real-time and immediately discarded. We do not store, log, or have persistent access to your email content.
14-day money-back guarantee. Email hello@mailmaster.tech with your order number within 14 days for a full refund. No forms, no justification needed. Full policy →
Yes — Premium includes team inbox and delegation features. You can share inboxes, delegate emails to team members, and track what's been handled and what's pending. Basic is designed for individual use (up to 5 personal accounts). For agency teams with shared client inboxes, Premium is the right choice.
If you spend 2 hours a day on email and MailMaster saves you 90 minutes — that's 7.5 hours per week. At $50/hour that's $375 saved every week. At $199 early access, the app pays for itself in under 4 hours of use. For most agency owners and founders, the real ROI is a deal closed because a follow-up didn't slip through the cracks — that single event often covers the cost many times over. Compare: Superhuman $360/yr, HEY $99/yr, MailMaster $199 once — then free forever.
