An SPF record can save your domain from spam and phishing by allowing you to keep a record of your authorized sources. Krystal highly recommends that their customers set up SPF for their respective domains. Here’s how you do it: 

Creating SPF record for Krystal

• Login to your Krystal account 
• On your Krystal control panel, click on “Email Deliverability” in the EMAIL section

• Navigate to the domain you want to set up SPF for and click on the “Manage button”
• Scroll down to the SPF DNS records section and click on “Install the suggested record” for SPF to configure it

The SPF mechanism used by Krystal is as follows: 

You need only create a new SPF record including this ip4 mechanism or just modify an existing one to add this mechanism. 

Finally, you can look up your record using our SPF record lookup tool, and enable DMARC for your domains to minimize spoofing attacks by taking a free DMARC trial.
