Email Delivery for Rails Folks

on YouTube ↗34m

" summary

Covers concrete delivery steps for sending bulk mail: use PowerMTA or Postfix, publish SPF/DKIM/DMARC, expose postmaster and abuse mailboxes, and implement list-unsubscribe and precedence headers. Warm up IPs starting around 5,000/day and aim for ~20,000/day per dedicated IP before scaling toward larger volumes, keep marketing and transactional on separate IPs, subscribe to ISP feedback loops to remove complaints and bounces, and require confirmed double opt-in to avoid spam traps and protect sender reputation.
