AWeber – What’s Email Authentication? How Does It Apply To Me?
Along with other technical standards we actively employ and adhere to in order to ensure industry leading deliverability, AWeber authenticates the email messages we send for our users.
Although it’s not the only factor involved with email deliverability, it is an important one, and understanding that we authenticate your email is essentially all you need to know about it if you are an AWeber user.
But why do we authenticate email? Read on for a better understanding of this important tool.
Understanding Email Authentication
ISPs continuously work to rid their networks of spam. This becomes increasingly difficult as spammers employ new techniques to avoid blacklisting and content filters.
One tactic that spammers often use is email forging (making a message appear to come from one domain/source, while actually sending it from another).
ISPs combat email forging with various forms of Email Authentication – essentially, having the owner of a domain provide a list of mail sources that are “legitimate” and that they take responsibility for. That way, if an email message purports to be from that domain, but isn’t listed in that domain’s legitimate mail sources, the ISP can refuse the message.
There’s More Than One Authentication Standard
Not all ISPs use the same technology to authenticate incoming messages, and so in order to get the best email deliverability possible you need to use each of the major authentication standards.
At present there are three major authentication standards:
- Sender Policy Framework (SPF)
- Sender ID
- DomainKeys and DomainKey Identified Mail (DKIM)
