Haven’t we all received emails that seem to be from our bank, our credit card company or even from ourselves but they were fake emails?

How do I make Mailjet an authorized sender?
To set Mailjet as an authorized sender, you will need to customize your SPF record. You can find step-by-step instructions at: SPF & DKIM Authentication Guide.
SPF & DKIM authentication cannot be done for free webmail accounts like Google, Yahoo, and Hotmail. You should consider only using email addresses that are linked to your website instead of free webmail addresses. Read more about why you should avoid free webmail as a sender address.
