What’s the difference between marketing email and transactional email?

Usually automated one-to-one emails, like a purchase confirmation email after an e-commerce transaction, are considered transactional. The content is information-based, that is completing some transaction process the recipient has started. Transactional email is sent to individuals as opposed to groups and is generally sent via API integration.

  • Purchase confirmations
  • Password resets

  • Account creation notifications
