SPF stands for Sender Policy Framework. It is a TXT DNS record, which ensures mail servers will only accept emails you send from a list of trusted servers you set up using SPF records. This ensures that only your own email server can deliver mail to these addresses.
If you use Siteground for your email transactions, SPF is enabled for your domains by default. However, if you still want to modify your SPF settings for your domains:
Log in to your Siteground account
Open Site Tools
Navigate to Emails
Click on Athentication > SPF
Note: After making the necessary SPF record changes, it will take your DNS up to 72 hours to process the changes.
