How to setup an SPF record on your domain
To prevent emails being flagged as SPAM, you can set up an SPF record on your domain with the steps below:
If you have no SPF record on your domain, simply publish the following SPF record wit the command:
v=spf1 include:sendgrid.net -all
If you already have an SPF record, simply insert INCLUDE:SENDGRID.NET right before the terminating mechanism in the record.
For example, If your current SPF record looks likethis:
v=spf1 a -all
update it to:
v=spf1 a include:sendgrid.net -all
