Sender Policy Framework, it’s an email authentication protocol or it’s also called as validation system that allows the domain name owner to define a list of IPs, only this list can send emails on behalf of this domain.
Well, simply it’s your address that comes after the “@” in your email address.
Well as we all know the importance of emails in the business communication, and how it’s important for any company to protect its name, so here comes the importance of setting SPF.
No one wants to risk sending a message with his name with a content that he knows nothing about and could risk his work or the whole company failure and loss of clients.
Other than protecting your name, SPF ensures that your email is sent to the intended place, which is the inbox of the recipient.
