To put it simply, DomainKeys Identified Mail (DKIM) is a small, encrypted digital signature that gets put into your email headers and lets inboxes like Gmail know emails are really coming from you, rather than a spammer.

DKIM enables domain owners to “sign” the emails being sent from their domain, much like you might sign an important document to prove it’s really coming from you.

It’s important to note that DKIM verification is only available for custom domain senders. In other words, if you’re sending emails from a free email address (like Gmail or Yahoo), you will not be able to set up DKIM.

You’ll need to configure your DKIM settings by pasting a set of generated keys from your Flodesk account into the DNS settings of your domain provider (like GoDaddy.com). Once you do so, the process of validation can take up to 48 hours.

For a detailed walkthrough on how to authenticate your domain (via DKIM and SPF) in Flodesk, review this guide.
