Write it, automate it, send it safely.

Automate

Build steps: emails, waits from 1 minute to 90 days, If/else paths and tags. Each person goes through once.

New blog posts by RSS

Send safely

Send through Amazon SES from your own domain. A new domain warms up. Sending pauses when bounces or complaints rise.
