How it works

Three steps. Zero friction.

01

Track

Click one button when you send an important email. That's it.

02

Monitor

We watch for replies on that specific conversation. Nothing else.

03

Alert

No reply before your deadline? We send you one reminder. That's it.

You send important emails.
Then you forget to follow up.

TRENKSY watches your conversations and reminds you only when it matters.
