Transactional email, explained.
What is transactional email?
Transactional email is a message a customer expects after an action: a password reset, purchase receipt, booking confirmation or account update. Your application sends it to the person involved. Newsletters, promotions and audience campaigns belong in Email marketing.
Can I use SMTP instead of the API?
Yes. Bird SMTP and the Email API use the same sending infrastructure, domain verification, suppression handling and reporting. Choose the submission method your application supports.
Does delivered mean the email reached the inbox?
Delivered means the receiving mail server accepted the message. Inbox Insights measures inbox and spam placement separately through seed accounts and a measurement panel.
