What is Email Authentication?

While email is one of the most commonly used communication frameworks in modern technology, it should come as no surprise that it is also one of the most common platforms targeted by malicious actors. In a recent Cisco Systems report, it was noted that nearly 90% of email sent every day are spam. This includes phishing, spoofing, reputation hijacking, and more. That’s why a demand for newer security technologies and authentication protocols were born. Generally defined, email authentication is a multi-method approach to securing email communications using either IP based and/or cryptographic standards. Generally there are three primary standards that people use to authenticate email.

Three Primary Email Authentication Standards

SPF

Sender Policy Framework, allows senders to specify which IP addresses are allowed to send email for their domain.

DKIM

DomainKeys Identified Mail, uses public/private key cryptography to verify that the message was not altered in transit.

DMARC

Domain-based Message Authentication, Reporting & Conformance, is a standard that allows domain owners to define a policy for their SPF and DKIM authentication.

Email Authentication at SocketLabs

How To Authenticate Email

The good news is that any sender using SocketLabs as their email service provider is automatically using authentication from a SocketLabs domain in the background. This practice helps apply necessary authentication and improve deliverability through a pre-established domain reputation from SocketLabs. We highly recommend that customers looking to establish their own sender reputation and apply email authentication from their own domain look towards white-labeling their email.

White-Labeling

White-labeling is a process that helps senders make their email appear as though it it directly from their domain. It is a process that involves configuring DNS entries with your domain’s DNS provider. Senders choose to white-label their email for a number of reasons but typically, white-labeling your email helps to isolate your sender reputation and build a reputation for your domain. To learn more about how to white-label DKIM, SPF and more in our White-label Knowledge Base article here.

We have recently chosen Socketlabs as our SMTP provider because they are really professional, their services are good, fast and nicely supported by the Socketlabs team. The service is good because the emails sent via the SMTP are always delivered and there is a really nice web console where you can check the status of all emails sent. Their support is very fast to reply when you have a question.  It was also very fast and well documented to get up and running.  After investigating SMTP providers Socketlabs appeared to us as the best SMTP provider that fit our needs.  We are happy with them!

I have been fighting to get your competitor to work for months.... no phone number, just an awkward way to 'submit a ticket’. I signed up with you today and within 30 minutes I was up and running. I made a phone call to your support team and they would not end the call until they were sure that I understood everything perfectly. You guys are great. Thank you.

What is SPF? Sender Policy Framework (SPF) is one of the primary means of authenticating email messages as they transit the Internet. The importance of SPF is growing as additional technologies, such as DMARC, are built on top of the standard.
