Email Authentication: What is SPF? (Sender Policy Framework)

A Sender Policy Framework (SPF) authorizes certain servers to send email using your domain.

SPF (Sender Policy Framework) records are TXT records on your domain that authorize certain servers to send email using your domain name. Our sending systems automatically configure SPF for all our customers which means that you don't need to create an SPF record or modify an existing one to use any of our ecard delivery service or automated greeting services.

You could still add us to your existing SPF record. As an example, you could do this by simply adding include: example.com to your existing record or by creating a new one.

Note that example.com would actually get replaced by a domain we provide to customers.

For example, if you send email with both G-Suite and us, your SPF record might look like this:

v=spf1 include:_spf.google.com include:example.com ~all

If you send email with both Microsoft 365 and us, your SPF record might look like this:

v=spf1 include:spf.protection.outlook.com include:example.com ~all

If you would like to add us to your existing Sender Policy Framework, please contact us to ask us for what domain to include in your SPF record.
