What is the difference between Sendinblue and Sendinblue SMTP?

Sendinblue is our service for sending newsletters (or emails targeted to many contacts at once), and Sendinblue SMTP is for sending non-promotional emails (or custom emails for a single contact).

What is a transactional email? A transactional email is sent as a result of a contact's request or action, such as a purchase confirmation, a reset password email, alerts, etc.

Synergies between Sendinblue and Sendinblue SMTP are essentially technical:

  • improve your deliverability
  • hard-bounce pooling and avoid returning an email to a contact that has resulted in a hard-bounce. With Sendinblue SMTP, your hard-bounces will automatically be imported to your Sendinblue account to avoid making the same mistakes with your regular newsletters.
