Email Authentication: Introduction
Email authentication, also known as domain authentication or validation is the process of verifying that an email is really sent from you or your business. It acts as a digital signature to verify your brand, identity, and reputation so that ESPs will place your email in the user inbox. Thereby the receiver of an email and the mailbox provider can confirm the authenticity of the sender. If the ESPs fails to verify the sender authentication, it may reject your emails or will do some additional checks to ensure whether it should be delivered on the user inbox or on the spam/junk folder.

ESPs such as Gmail, Yahoo and Outlook use email authentication to ensure whether something is spam, or is worth blocking completely to secure their users.

3 Primary Methods of Email Authentication
There are high chances of being filtered or blocked by major ESPs with the lack of email authentication. As a genuine business, authentication is not an option; it is critically important to ensure your sender reputation is protected. There are three primary methods of authentication:
1. SPF
2. DKIM
3. DMARC
1. SPF
The Sender Policy Framework (SPF) is an email-authentication method which is utilized to stop spammers from sending messages on behalf of your domain. With SPF, companies can publish licensed mail servers. Together with the DMARC related data, this offers the receiver data on how dependable the sender of an email is. SPF utilizes DNS (Domain Name Service) which gives you, as an email sender, the way to determine which email servers are allowed to send an email for the benefit of your domain.
2. DKIM
Domain Keys Identified Mail (DKIM)- This email-authentication technique enables the recipients to ensure that an email was surely sent and authorized by the owner of the domain. Such authentication is done by giving a digital signature to the email which is part of the header and is secured with encryption. DKIM signature is not visible to the user and the validation is mostly done at the sender level.
The mailbox service provider when receives the email which is signed by DKIM, it is certain about the authentication of the email. Implementation of DKIM along with SPF will not only improve your email deliverability but will also save your domain from any misuse done by an outside source.

3. DMARC
Another email authentication protocol is known as DMARC which stands for Domain-based Message Authentication Reporting and Conformance. DMARC is an email approval framework intended to shield your sender domain from being utilized for email spoofing, phishing tricks, and different cybercrimes.
DMARC uses the current email verification systems, Sender Policy Framework (SPF) and Domain Keys Identified Mail (DKIM).
DMARC is an extension to the two existing authentication systems described above namely SPF and DKIM. DMARC allows the domain owner to publish their policy with detailed specification of the following:
• The mechanism that is employed (SPF or DKIM or both)
• How to deal with the email failures
• How to report for events that are covered in the policy etc
Conclusion
Such email authentication systems ensure the legitimacy of domains which is done through a complete analysis and scrutiny. Email authentication protects email sender reputation and in the process protects the brand as well. Therefore, it is highly recommended that besides the process of validation and verification of the target email ID's, go head to establish your own email authentication too. This will help you to hit on your subscriber’s inboxes and to stay out of the spam/junk folder.
