Beta — already in testers' hands

Track the emails you sent that never got a reply.

An unanswered email you sent doesn't sit in your inbox as unread -- so nothing reminds you it's still open. FilsOnly tracks both directions of a conversation and nudges you when your side is the one still waiting.

The emails you sent

You sent it. They haven't answered. Now what?

This is the other half of the follow-up problem: not what you forgot to answer, but what you're still waiting to hear back on. A proposal, an invoice, a candidate who went quiet mid-process -- these don't show up as unread mail, so nothing in your inbox flags them once the moment passes.

FilsOnly tracks both directions of a thread. If you sent something and the reply never came, it's the same kind of quiet conversation -- and it gets the same nudge.
