SPF: Prevent Email Being Flagged as Spam

How do I make sure email coming from my ECP account isn’t marked spam?

Since Email Center Pro is sending mail on behalf of your domain, some servers will determine this behavior to be suspicious. We recommend that users set up a Sender Policy Framework (SPF) record, telling your domain (yourcompany.com) that your ECP account is an "authorized sender" (not spam).

Set up an SPF Record

We provide a link, below, to a SPF Setup wizard. You will need to know your domain name and the subdomain for your Email Center Pro account (mycompany.emailcenterpro.com).

Click this link to open the SPF Setup Wizard: http://old.openspf.org/wizard.html?mydomain=example.com

Add Email Center Pro as a Valid Sender

In order to list Email Center Pro as a valid sender, add your account's domain to the list of mx references. The resulting string should look similar to this:

v=spf1 a mx mx:SUBDOMAIN.emailcenterpro.com ?all

where SUBDOMAIN is replaced with your Email Center Pro subdomain.

The instructions may sound complicated, but if you have access to a domain control panel, this should be fairly straightforward to set up.

We would be happy to help walk you through creating an SPF record and getting it set up in your domain control panel. If you have an SPF record set up already, you will need to make sure to run through the wizard instead of just copying the record provided above.

More information

Many mail servers use the Sender Policy Framework (SPF) to determine which mail servers are to be considered "authorized" senders for that domain. The way this is implemented is using DNS records, similar to the type that tell Web browsers where to go when a user types in www.yourdomain.com.
