As a best practice, Mailjet recommends that any business using the email marketing industry standards configure SPF authentication with their domain provider before sending any emails. This allows mail servers to authenticate emails that originate from your domain and enhances the deliverability of your messages.
Within the Mailjet dashboard, you will have to follow the instructions in order to create the SPF record needed for email authentication. Once Mailjet has provided you with information about how to create DNS records, you will need to contact your service provider and have them created.
Creating SPF record for Mailjet
Login to your DNS management console
Navigate to Tools & Settings > DNS Template
You need to edit the DNS TXT record related to SPF
An SPF TXT record for Mailjet will have the following syntax:
yourdomain.com TXT v=spf1 include:spf.mailjet.com -all
Publish this record in your DNS records section for your respective domain.
Note: If you don’t have an SPF record previously for your domain, simply publish the above-mentioned record to enable SPF for outgoing emails using Mailjet. If you do have an existing SPF record in your DNS, you need to modify it to include Mailjet, as shown below:
Previous SPF record: v=spf1 include:spf.zoho.com -all
