SPF and DKIM are fundamental components of email authentication and help protect email senders and recipients from spam, spoofing, and phishing.

Sender Protection Framework (SPF) is a form of email authentication that checks whether an email message has been sent from an authorized mail server. This is to detect forgery and to prevent spam.

DomainKeys Identified Mail (DKIM) works by adding a digital signature to the headers of an email message. This ensures that emails you sent can be proven to be authentic and unaltered, thereby preventing email spoofing and harmful spam.

When used together, SPF and DKIM authentication form a powerful combination that ensures business critical emails reach your recipient’s inbox and don’t end up in spam boxes.

Here are the instructions for setting up SPF and DKIM authentication for your domains. You will need to add one (1) TXT record and three (3) CNAME records to your domains DNS settings:

1. Login to your web hosting account cPanel
2. Find the Domains section and click Zone Editor

3. Click the Manage button for your domain.

4. Click on the Add Record button and add the TXT and CNAME records that was emailed to you.

See the sample DNS Records excel file below:

5. After adding the records, your DNS settings should contain 4 new records (sample shown below)
