SPF

Sender Policy Framework (SPF) is an email authentication standard that compares the email sender’s actual IP address to a list of IP addresses authorized to send mail from that domain. The IP list is published in the domain’s DNS record.

How do I add it?

If you do not have an SPF record for your domain you must create a TXT record with the value:

v=spf1 include:sendgrid.net ~all

I already have an SPF record

You see a TXT record with SPF already? You just need to add to it. If your record looks like this:

v=spf1 a mx include:_spf.google.com include:spf.protection.outlook.com ~all

You would just need to add our lookup at the end of the string, before the ~all mechanism, like so:

v=spf1 a mx include:_spf.google.com include:spf.protection.outlook.com include:sendgrid.net ~all
