How to Get a DKIM for a WordPress Domain
Comply with the spam rules
If you have a business domain email address based on a WordPress.com site, you can easily update your sender identity in your tinyAlbert account. Then, you can register a DKIM.
Click to understand the importance of a DKIM.
To add a CNAME record, enter the values you see below in those fields. Then click Add DNS record. While saving the record, you might see a warning message. Just click Yes.
In this example, I manually enter tec1._domainkey. WordPress auto-fecthes the domain (e.g. .altcurrentpress.com).
If DKIM is successfully set up, the status changes to DKIM verified. If you have a problem, contact our support team.
Setting up and verifying a DKIM record does not take much time, but it does yield great rewards. You're in compliance, and can rest easy that you've reduced the risk of getting tagged as a spammer.
