How to Set Up/Modify SPF for Mailjet
The following description addresses how to update a Domain Name Service (DNS) record to use SPF with your custom domain in Mailjet.
To utilize a custom domain, the Mailjet provider requires an SPF TXT record be added to the DNS record. This TXT record is then used by DNS to recognize email servers allowed to send messages on behalf of your custom/third-party domain. To determine whether a correspondence from the specified domain comes from an authorized messaging server, the recipient system relies on the implemented SPF TXT record. At that point, the message is either accepted, quarantined, or rejected by the email receiving system.
To implement SPF authentication for your domain, you will need access to your DNS records in the domain hosting account. Important: If you already have an SPF record, then you should modify that existing record. You must not have more than one SPF record.
For convenience, be sure to log in to your Mailjet account to verify your domain and copy your TXT records. Mailjet utilizes an include mechanism during the set-up process. For example, the following scenario is the most common and would pass SPF:
v=spf1 include:spf.mailjet.com ?all
If you send email from IP 1.2.3.4 for the domain “yourcompany.com” and that domain’s SPF record includes servers.mailjet.com and the IP address passes the SPF record, this mechanism will pass.
