If you want to allow constant contact to send emails on behalf of your domain, you need to setup constantcontact SPF and modify the records to include constant contact. Otherwise, your emails sent using the application will not be DMARC compliant and will fail authentication. This document will show you how to configure SPF for constant contact. 

Steps to Setup SPF for Constant Contact

• Login to your DNS hosting provider’s cpanel 

• Navigate to the domain for which you want to setup SPF for constant contact

Now, If you have a pre-existing SPF record in your DNS: 

You need to add include:spf.constantcontact.com to your previous SPF record. Hence, if your previous SPF record was v=spf1 include:_spf.google.com -all, your new record will be: 

v=spf1 include:_spf.google.com include:spf.constantcontact.com -all

Note: Make sure you have a single SPF record configured for your domain. More than one record will completely invalidate your SPF. 

Now, If you don’t have a pre-existing SPF record in your DNS:

Simply add the following DNS TXT SPF record to your DNS: 

v=spf1 include:spf.constantcontact.com -all

Finally, you can lookup and validate the correctness of your SPF record using our free SPF record generator tool, to ensure that your record is error-free. With this, you will have successfully configured SPF for Constant Contact.
