How it works

The detail.

A curve, not a step function

Linear ramps trigger spam filters. Autocloz uses a sigmoid that mimics organic mailbox growth — gentle for the first 5 days, ramp through days 6-15, plateau by day 21. The math is built in; you just enable warmup.

Placement, not just acceptance

A 250 OK from Gmail doesn't mean inbox. Our seed-test probes mail real monitored mailboxes across providers and report which folder the message actually landed in — inbox, promotions, spam, or missing.
