Tracking is free. You only pay to be invisible.

The free plan is not a trial and has no cap on how many emails you track. Pro removes the small Seenbox line from the foot of your emails, keeps your history forever, and mails you a summary each morning.

Three ways in.

Every plan tracks an unlimited number of emails. What changes is whether your recipient can see that you are tracking, and how long we keep the receipts.

Questions worth asking.

Straight answers, including the ones that are not flattering.

It is genuinely free and it does not expire. You can track an unlimited number of emails, see every open with its timestamp, and get browser alerts without ever entering a card. The free plan adds one small line at the foot of your tracked emails and keeps 30 days of history. Pro removes both.

Stop sending email into the dark.

Track your next email in under a minute. No card, no extension, no mailbox access, and no cap on how much you send.
