SMTP is a communication protocol used for transferring email to electronic mail servers.
SendinBlue SMTP is the transactional email service of SendinBlue.
A transactional email is sent to certify a transaction or action. Actions such as these can trigger a transactional email: email for an account creation, order confirmation emails, recovery password emails, and all your non-promotional emails.
Just like your regular campaigns, SendinBlue SMTP also allows you to view the history of sent emails, openings, clicks, hard bounces and many other information.
To retrieve your SMTP password, log in your SendinBlue account, click on your name on top right menu and choose "SMTP & API".
Under the SMTP tab, you’ll find your SMTP password. Copy it.
