The follow-up email client — for people who live on replies

Your next deal is already in your inbox. Don’t let it die.

Deals rarely die from a no — they die from silence. Simple Mail Client shows every thread still waiting on a reply, so you follow up before it goes cold.

One click, no email needed. Free while in early access.

Email dies quietly. Not anymore.

Gmail and Outlook treat every email the same: it arrives, you read it, it sinks. Nothing tells you that the client from two weeks ago never answered — or that you never answered them. Simple Mail Client is built around that one blind spot.

See who owes you a reply

Every open conversation stands on a timeline by how long it’s been waiting — green when it’s fresh, red when it’s about to die. Amber means the ball is in your court. No labels to maintain, no reminders to remember to set: if a thread is waiting, it’s on the board automatically.

Answer it or mark it done and it leaves the board. If they write again, it comes back on its own.

Heavy inbox? The important mail can’t drown.

When enough mail pours in, just keeping the important threads visible becomes a job of its own — and that’s exactly when follow-ups die. So sorting here works by sender, not by message: decide once that newsletters live in Feed and that a real client belongs in Main, and every email they ever send follows the rule.

Automated senders are detected and suggested for you — a few minutes of sorting covers most of your volume, and Main becomes what an inbox should be: just the conversations that matter, with nowhere to hide.

Nudges where you actually look

You don’t live in your inbox — so the reminders don’t either. Once a day, Telegram hands you a short digest of the conversations that have waited too long, with Done and Snooze buttons right in the chat. Handle a follow-up without ever opening the app.

And when real mail lands — not newsletters, not receipts, the mail you actually sorted into Main — you get one quiet ping, seconds after it arrives.

Your mail stays yours

Simple Mail Client speaks plain IMAP and SMTP against the accounts you already have — Gmail, Outlook, or your own domain. Nothing is forwarded, nothing migrates, no new address to announce. Delete it tomorrow and your email is exactly where it always was.

That makes leaving free: stop using it tomorrow and your inbox is exactly as it was — the conversations never left your mail server.

Plain IMAP + SMTP

Works with any provider you already use.

No forwarding, no migration

Your mail never leaves your mail server.

Leave anytime

Stop using it and your inbox is exactly as it was.

Questions, answered

How is this different from Boomerang, Right Inbox, or Gmail reminders?

Those are plugins where you set a reminder on individual emails — and the follow-ups you forgot to set reminders for still slip. Simple Mail Client is a standalone email client that tracks every conversation automatically: if a thread is waiting on a reply, it's on the board, whether you remembered it or not.

Does it work with Gmail, Outlook, or my own domain's email?

Yes — anything that speaks IMAP, which is nearly every mail provider. You connect with your email address and password (Gmail requires an app password), and sending goes through your own SMTP.

Where does my email live?

On your mail server, exactly where it is now. Simple Mail Client syncs a copy over plain IMAP to track conversation state — no forwarding, no migration, no lock-in. Walk away any time and your inbox is untouched, because it never moved.

I get a lot of email — how does the important stuff stay visible?

You sort senders, not messages: decide once that a newsletter belongs in Feed or a client belongs in Main, and every current and future email from that sender follows the rule. Automated senders are detected and suggested automatically, so a few minutes of sorting covers most of your volume — and the waiting graph only ever shows real conversations.

What are the Telegram notifications?

Two things, both optional: an instant ping when new mail lands in your Main inbox, and a short daily digest of conversations that have been waiting too long — with Done and Snooze buttons right in the chat.
