A bounce isn't just a missed send.

When you email an invalid address, it bounces. Inbox providers like Gmail notice. If it happens enough, they start treating everything you send as suspicious.

Reckon is optimized to work inside your automation flows, telling you which ones are likely to bounce.

Email Hygiene, in your flow.
