Don't worry, you don't need to know what SPF and DKIM are and how they work: we'll take care of them for you for AnthericaMail and e-mail.

However, if you are curious, we will briefly explain what they are and what they are for. They are protocols that ensure your e-mails not to end up in spam or are rejected by the recipient servers. 

There is a third protocol, DMARC. SPF, DKIM and DMARC work together to ensure the validity and technical reliability of an e-mail.
  • SPF (Sender Policy Framework): it ensures the reliability of the sender, verifying if it is authorised to send on its behalf. It does this by comparing the IP addresses linked to the domain and that from which the e-mail comes.
  • DKIM (Domain Keys Identified Mail): it's a digital signature affixed to sent e-mails.
  • DMARC (Domain-based Message Authentication, Reporting, and Conformance): developed to prevent spoofing, a spam technique in which the sender is forged, it is used by the sending domain to give instructions to the receiving domains on how to behave when they receive an e-mail from that sender and what are the technical characteristics it must have in order to be considered trusted.
