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 to one person as a result of an action triggered by the user. These are automated notifications such as welcome emails, shipping notices, order confirmations, password reminders, purchase receipts, etc. These emails are so important and give users peace of mind in knowing that their transactions have been processed properly.

What is the difference between email marketing and transactional email?

Marketing, or bulk emails are "one-to-many" emails, like a newsletter. Transactional emails are sent on a "one-to-one" basis; examples include a sign-up confirmation, or an invoice. To learn more, visit the Different Types of Emails page.
