HubSpot DKIM Setup

DKIM (DomainKeys Identified Mail) is an email authentication method that uses cryptographic signatures to verify that an email was sent from an authorized source and has not been altered in transit. 

This guide provides step-by-step instructions for setting up DKIM authentication for your domain in HubSpot, a popular platform for marketing, sales, and customer service.
