The ISN sends emails on your behalf each and every day. In order to maximize the sending success of the emails we suggest adding the ISN to your domain's SPF record. The SPF system, or the Sender Policy Framework was designed as an email validation system to prevent email spam by detecting email spoofing. This allows domain owners to explain who is allowed to send email on their behalf. You can add the ISN to your SPF record for your domain by adding the following include:

Thus, let's say your SPF record is currently:

v=spf1 ~all

After the update it would be:

v=spf1 ~all

If you have additional questions about SPF records please contact our support staff.

Adding an SPF record to your domain varies GREATLY between domains/providers. Unfortunately, there are no clear and concise directions we can provide that would help everyone. It would be best to contact whoever does DNS for your domain, or reference information that your domain host provides for adding SPF Records.
