Haven’t we all received emails that seem to be from our bank, our credit card company or even from ourselves but they were fake emails? The way emails are structured, spammers can and often do falsify the ‘from email address’ to send these types of spoof / spam emails. This is where SPF comes into place!

Sender Policy Framework (SPF) is a validation system that allows ISPs and webmail servers (Gmail, Yahoo, etc) to check if the incoming mail has been sent from an authorized server. Using the IP address of the sending server and the DNS records of your domain, ISPs can check if the sending server is authorised. If email is coming from an unauthorised sender, the emails will be marked as spam!

How do I make Esendex an authorised sender?

To set Esendex as an authorised sender, you will need to customise your SPF record.

SPF & DKIM authentication cannot be done for free webmail accounts like Google, Yahoo, and Hotmail. You should consider only using email addresses that are linked to your website instead of free webmail addresses.
