The Sender Policy Framework (SPF) is a simple email-validation system designed to detect email spoofing and prevent sender address forgery, in few words, detect and prevent fake addresses.
This is used to check that incoming mail from a domain comes from a host authorized by that domain's administrators. An SPF record indicates to ISPs that you have authorized FlipMail to send emails through your domain email address.
If your custom MAIL FROM domain does not have an existing SPF record, publish a TXT record with the following value. The name of the record can be blank or @, depending on your DNS service.
"v=spf1 include:amazonses.com -all"
Important: If you use "-all" as shown in the example, ISPs might block email from IP addresses that are not listed in your SPF record. Your SPF record must, therefore, include every IP address that you use to send emails. As a debugging aid, you can use "~all" instead. When you use "~all", ISPs will typically accept email from IP addresses that are not listed in the SPF record, but they might flag it. To maximize deliverability, use "-all" and add a record for each IP address. For examples of how to authorize multiple IP addresses, go to http://www.openspf.org/SPF_Record_Syntax.
If your domain already has an SPF record, then you must add the following SPF mechanism to the existing record.
Having the SPF set up in your DNS will make your emails be trusted by email service providers like Gmail, Yahoo, Outlook and the rest. More trust equals more hits on the inbox of your subscribers instead of spam.
