Cold email written from real outcomes.

Outlum lives inside Gmail and writes pitches ready to send. Backed by real outbound intelligence and pattern research, not generic AI guesswork.

How it works

From a short prompt in Gmail, to a pitch that actually lands.

Outlum is built around a closed loop: pitch generated, sent from your inbox, outcome tracked, system learns. Every send teaches the next.

Step 01

Pitch generated

From a short prompt in Gmail, Outlum writes the email, calibrated against patterns that actually get replies.

Step 02

Sent from your inbox

Connect Gmail or Outlook once. Outlum sends through your account so deliverability stays intact.

Step 03

Outcome tracked

Replies, opens, bounces — every signal feeds back. Outlum sees what worked and what didn't.

Step 04 · Loop

System learns

Outcomes inform the next pitch. The model improves with every send, getting sharper for you over time.
