MailSeenTransparency first
Our free plan shows a visible tracking badge once you pass 30 emails, because we believe the people you email deserve to know when they're being tracked.
Our story
Built so you never have to wonder if your email landed.
We got tired of sending important emails into a black hole. MailSeen exists to give you a simple, honest signal: did they open it, and when.
The problem
Email tells you nothing after you hit send.
You send a proposal, a follow-up, an application — then you wait. Was it opened? Ignored? Buried in a promotions tab? Gmail gives you no answer, so you guess, sending a "just checking in" note a week too early or a week too late.
That uncertainty costs real opportunities. Salespeople miss the right moment to call. Job seekers don't know whether to follow up. Founders can't tell if an investor ever opened the deck.
The solution
A read receipt for the real world.
MailSeen tracks your Gmail messages and tells you the moment they're opened — with a timestamp and an open count, right inside your inbox.
No dashboard to check, no separate app to open. Install it once and every email you send from Gmail is tracked automatically.
What we believe
Three things we will not compromise on.
Privacy by design
We only track opens on emails you choose to send through MailSeen. We never read, sell, or train models on the content of your emails.
Simple over bloated
MailSeen does one job well: tell you when your email was read. No CRM to learn, no dashboard to maintain.
