1. Why do you want to set it up?

SPF records tell mailboxes which hosts are allowed to send mail from a given domain. You can add SPF records in your DNS settings to easily prove your authenticity and help your email deliverability. So, why would you want to add the SPF record to your domain?

  • To be recognized as a valid sender.
  • To authenticate your domain and protect its good reputation.
  • To avoid anti-spam filters.
  • To score a high open rate and keep the bounce rate low.
  • To turn your response rate into a higher satisfaction rate.

2. How do you set up the SPF record?

The way you set up your SPF record depends on your domain host. Make sure you include all the applications which send emails for you in your SPF record. For example, if you’re using Google Apps (G Suite) to send your messages, you should include the following record:

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

Keep in mind:

  • An incorrect record will harm your domain’s reputation and affect the deliverability of your emails.
  • SPF has a limit of 10 DNS record lookups, so formatting your records properly is crucial.
  • It’s very important to set it in only one line.
  • Use “include” statement if you wish to add more values, for example, Sendgrid » or Mailgun »

Sendgrid

v=spf1 include:sendgrid.net ~ all

Mailgun

v=spf1 include:mailgun.org ~ all
