Beta — already in testers' hands

Forgot to reply to an email? It happens to everyone.

The email wasn't urgent when it arrived, so you meant to get to it — and then you didn't. FilsOnly watches your inbox for exactly this and nudges you days before it becomes the awkward reply, not after.

If you're here because you forgot one

You didn't ignore it. You just stopped seeing it.

An email isn't urgent the moment it arrives. You read it, you mean to answer, and your inbox moves on — new messages push it down, and nothing about the interface tells you it's still open. Three days later it's not a five-minute reply anymore, it's an awkward one.

That gap — between reading something and actually being reminded you never answered — is the specific thing FilsOnly is built to close.

Monday"Can you send over the contract?" arrives. You read it, mean to reply.
Wednesday"Just checking in..." arrives. Still no reply.
FridayFilsOnly: "Legal Team's contract has waited 3 days. Worth a reply today?"
