How it works

From inbox chaos to clarity in minutes.

No switching your email app, no CRM fields to fill in.

01

Connect your mailbox

You connect your own mailbox — no switching the app you write in. Gmail, Outlook, or any IMAP server.

02

See months of mail, organized

Inbox Horizon groups your mail by contact, hides the newsletters, and sorts threads by whose court the ball is in and how urgent it is.

03

Know your next move

See who you owe a reply — and let the AI suggest the next step, in your language.

Security

Your mail stays yours.

  • ✓Mail content is encrypted with a key unique to your account.
  • ✓Your mailbox password lives in an encrypted vault, never in plaintext.
  • ✓The connection to your mail server is always encrypted — we refuse to connect if the server doesn't offer STARTTLS.
  • ✓We read it to show you things. You always send — AI only suggests the text.
  • ✓Disconnect your mailbox whenever you want. Ask, and we delete everything.
  • ✓We don't sell your data or share it for advertising.
Design partners

I'm looking for a few people to shape this product.

I'm building Inbox Horizon on my own. Before it goes out widely, I want a handful of salespeople and agency owners who'll connect a real mailbox and tell me straight what's wrong with it. In return you get the SOLO plan free for good, and a direct line to me.

After launch, Inbox Horizon will start at $19/month. Design partners get the SOLO plan free, for good.
