SpamHero SPF, DKIM, DMARC and MX Records Setup for Domain Authentication

The email inbox providers require proof that you are who you say and your emails are safe to open. That's where domain authentication comes in. By authenticating your sender email domain, the ESPs recognize you as a legitimate source. SPF, DKIM, and DMARC are commonly used sender validation standards. You can obtain these DNS records from an authorized platform like SpamHero. In this article, we will configure the SPF, DKIM, DMARC, and MX, records and add them to the DNS provider to protect your emails against spamming and spoofing. So stay tuned!

3. Here you'll find the SPF and DKIM records, add these to your DNS provider.

Merge Multiple SPF Records:

Due to the limitations of the DNS providers, you can not add more than one SPF record to your domain. If there is an existing SPF record, merge it with the SpamHero SPF to avoid conflicts.

Setup MX Records:

If your domain has existing MX records, there is no need to add SpamHero MX records. Adding MX records from multiple sources can confuse the servers and cause conflicts.
