Transactional vs Marketing Email: Keep Them Separate
The difference between transactional and marketing email, and why mixing them on one domain risks your most critical messages.
Transactional email is triggered by a user action (receipts, resets). Marketing email is promotional and sent to many. They have different goals — and should never share a sending reputation.
Why separate them
A newsletter that earns unsubscribes and complaints should never threaten the delivery of a password reset. Mix them and one bad campaign can stop critical mail from arriving.
How to separate
- Use distinct subdomains, e.g.
mail.for marketing. - Keep separate sending streams or IP pools.
- Authenticate each subdomain independently.

Different rules apply
Transactional mail goes to one consenting user and rarely needs marketing-style unsubscribe; bulk marketing always needs an unsubscribe link and consent. Keeping them apart keeps you compliant too.
