Transactional Email vs Marketing Email: Different Rules, Different Risk
Receipts, password resets, and newsletters are not the same — authentication, volume patterns, and why to separate them.
Transactional mail is triggered by a user action — order confirmed, password reset, invite accepted. Marketing mail is broadcast to a list. Mixing them on one stream without discipline hurts both.
Use the API for transactional
OquMail's email API sends programmatic messages with per-key scopes, delivery logs, and optional no-reply mode — keeping receipts separate from human conversations in the inbox.
