VERDICT

Should I use BYOMailer?

BYOMailer helps SaaS founders send newsletters, sequences, and automations through their own AWS SES account with flat pricing, no contact limits, and migration help on paid plans. - byomailer.com

Depends. Buy if you're a technical SaaS founder with a large list getting crushed by per-contact pricing — $139/mo vs Mailchimp's $666 at 100K contacts is real money. Skip it if you won't manage AWS IAM, DNS records, and your own deliverability.

Confidence

Medium. Based on ~15 public sources; mostly founder-published pages plus one Reddit thread. No independent review sites found.

Two bills: BYOMailer plan fee plus separate AWS SES usage

Savings math assumes 4 emails per contact monthly; heavier sending raises SES costs
