How to Setup SPF, DKIM, DMARC records for Nutshell?

Email spoofing has become a major threat to businesses these days, that's why email inbox providers like Google require you to comply with its security standards strictly.

SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication Reporting and Conformance) are the commonly used security standards for domain authentication and email verification.

There are some other verification records like bounce domain, return path, and click tracking records that add an extra layer of security to your email campaigns. Nutshell provides you all the necessary records to protect your email communication.
