Transactional email, explained.
What is a transactional email service?
A transactional email service sends messages that a customer expects after an action: a password reset, purchase receipt, booking confirmation or account update. Your application supplies the recipient and message; the service handles sending and delivery reporting. Newsletters, promotions and audience campaigns belong in Email marketing.
Should I send transactional email with SMTP or the Email API?
Choose SMTP to keep your application’s existing message-building code. Choose the Email API for structured request fields and published templates, with access through Bird’s SDKs, CLI and hosted MCP. Both use the same sending infrastructure, domain verification, suppression handling and reporting.
Does a delivered transactional email mean it reached the inbox?
Delivered means the receiving mail server accepted the message. Inbox Insights estimates inbox and spam placement from seed accounts and a measurement panel.
Scale without losing control.
