MailMaster is one app for every email account you own
Gmail, Outlook, Apple Mail, Yahoo, iCloud — unified in one desktop app, with AI that reads your inbox and handles what you don't have time to.
Why I built this
I was managing multiple email accounts — different providers, different tabs, different contexts — and found it genuinely exhausting. The switching, the missing things, the mental overhead of keeping track of who needed a follow-up and when.
I looked at every email tool available. Superhuman is excellent but costs $30/month and works primarily with Gmail. Spark is well-designed but has no follow-up automation. Everything else was built for email marketing, not for managing real conversations.
Nothing did what I actually needed: connect all my accounts in one place, surface what mattered, and handle follow-ups automatically.
So I built MailMaster. It's designed around the problem I had — and the problem I hear from agency owners, consultants, and freelancers every week.
Every inbox you use. One app.
MailMaster connects Gmail, Outlook, Apple Mail, Yahoo, iCloud, and any IMAP/SMTP account into a single unified inbox — then adds AI that drafts replies, runs follow-up sequences, and surfaces what actually needs your attention today.
Email is still how business gets done. I'm not trying to replace it — just to make it work for you instead of against you.
You pay once and own it. Software you depend on should not have a monthly fee that never ends.
Your email stays yours. MailMaster does not store, read, or retain your email content on any server.
MailMaster is an early-access product built by one person. It is not perfect. If something breaks or a feature is missing, you can tell me directly and I will fix it.
I'm a solo founder. I built MailMaster because I needed it and nothing on the market did what I wanted at a price that made sense. I write every line of support, ship every update, and read every reply.
If you have a question, a bug to report, or a feature you'd like to see — you're talking directly to the person who will deal with it. That's the one advantage a solo product has over a VC-funded team: you actually reach the person who cares.
