Learn how to add an SPF record to your domain:
This video will walk you through setting up an SPF record on one of your domains. Please note that this is not the same as turning on SPF in your Junk Email Filtering Settings.
The first step to adding an SPF record to a domain is to log in to the Account Control Center. Then, in the left sidebar, click Domains. A drop-down will appear. Click Manage Your Domain Names here. Find the domain name that you would like to add an SPF record to and click its name.
This will take you to your domain’s management page. Scroll down until you find Manage Custom DNS Records. Click its button, here. Then click Add DNS Record. This will take you to the next page, where you can select the Type of Record. Click the drop-down here and select TXT. Then click Proceed.
This next page is where you actually input the SPF record. First, define the hostname. If you want to apply this SPF record to a subdomain only, input the subdomain name in the text field next to Hostname. If you want the SPF record to encompass all of the domain, leave this text field blank.
Under that, enter your SPF record into the text field next to Text Record. When you have finished, click Create TXT Record.
