The SPF record ensures that remote mail servers will accept mails from your domain only from your server. This is important in fighting spam and email forgery.

It is especially useful to create an SPF record for your domain in case you have problems with bounced back messages you have not sent. For more information how SPF records can help in such cases please check this article.

SiteGround customers can easily enable and manage SPF records for their domains from cPanel > Email Authentication.
