Sender Policy Framework (SPF) is an authentication scheme that allows a domain to publicly state which IP addresses (email servers) are allowed to send email on its behalf.
If you don't have an SPF record, there is no requirement to create one although that will decrease the success of email deliverability from our server. If your domain publishes an SPF record, we strongly recommend including RescueGroups.org servers.
If your organization uses our hosting services for email hosting, the details would be different than what is described below. Please read more about how to Set up an SPF Record for RescueGroups.org Hosting Service
Edit your domain's existing SPF record
If your domain already has an SPF record, you can include our email server easily by adding the following to your existing DNS text (TXT) record that defines your domain's SPF record:
Create a new SPF record
If you do not have an SPF record, we would suggest creating one on your domain and be sure to include all services that may send email on your behalf, such as MailChimp or Constant Contact. You can reach out to the other services to find out what information they recommend you add to your domain's SPF record.
Here's an example TXT record if RescueGroups.org is the only service sending email on your behalf:
v=spf1 ip4:18.104.22.168 ~all
