About Mailjet

Why are my emails showing as sent and not as delivered?

Mailjet can process and send tens of thousands of emails very quickly. For an email to be ‘delivered’, it must be accepted by the destination server. However there are several reasons your emails may show as ‘sent’ (and not delivered) and steps that you can take.

What is a transactional email?

Transactional emails are sent due to an action triggered by the user. These can be automated notifications such as welcome emails, shipping notices, order confirmations, password reminders, purchase receipts, etc.
