A transactional email is a type of triggered email. It is deployed based on an action taken between an individual and the sender. You do not need to be opted into the sender’s marketing email program to receive a transactional email.
Common transactional emails include:
- Email subscription confirmation: sent when you sign up for a sender's email marketing program
- Purchase confirmation: sent when you complete an online purchase
- Password reset: sent when you request a password reset
