The impact of email authentication on email deliverability
Email marketing is a vital part of any online business, but it comes with its fair share of challenges. Amongst these challenges, one of the most significant is email deliverability. It is crucial to ensure that your emails are reaching your subscribers' inboxes and not getting lost in their spam folders. Unfortunately, this is easier said than done, and many businesses struggle with high spam rates. But what if we told you that there is a way to significantly reduce this problem? Enter email authentication.
Email authentication is a method used to verify the sender's identity, preventing the occurrence of fake and phishing emails. It involves adding a digital signature to your emails that get verified once it reaches the recipient's email client. Authentication allows the recipient service to validate that the sender is who they say they are, and the message is not spoofed. By implementing authentication, email services like Google and Hotmail establish trust between email senders and receivers. As a result, your emails' deliverability rate increases, and users are more likely to receive your emails in their primary inbox folder.
There are four main types of email authentication standards: SPF, DKIM, DMARC, and BIMI. Let's take a brief look at each of these:
SPF: Sender Policy Framework (SPF) is a simple email validation system that detects spoofed emails. The system checks if the email sender has authorized the IP address or domain from which the email is sent. If the IP address or domain is not authorized, SPF can reject or flag the email as spam.
DKIM: DomainKeys Identified Mail (DKIM) also checks the email's authenticity by adding a digital signature to the email messages sent by the company. The signature, which is encrypted, is added to the email header and validated by the recipient's server.
DMARC: Domain-based Message Authentication, Reporting, and Conformance (DMARC) is a protocol that builds upon SPF and DKIM to provide additional features. DMARC allows senders to indicate the type of action required when an email does not pass SPF or DKIM checks. This can include rejecting, quarantining, or forwarding the email to a specific mailbox.
BIMI: Brand Indicators for Message Identification (BIMI) is a relatively new email authentication protocol that allows companies to add a logo to their emails. To use BIMI, companies must have a verified and validated DKIM, SPF, and DMARC record. The logo appears beside the email message in the user's inbox, helping to establish trust between the sender and recipient.
Now that we understand what email authentication is and the different authentication methods available, let's dive into the impact email authentication can have on your email deliverability rates.
Email authentication helps prevent your emails from being mistakenly flagged as spam, significantly increasing your email deliverability rates. ISPs are more likely to deliver emails from authenticated senders to the primary inbox and not the spam folder. In addition, authentication makes your emails less attractive to hackers and spammers, who often spoof email addresses to steal personal information from users.
A recent study by the Global Cyber Alliance found that companies that implemented DMARC had an average of 10% more emails delivered to users' primary inboxes instead of the spam folder. Furthermore, the study found that almost 40% of all email domains receiving emails were already implementing DMARC, showing how widespread its adoption has become.
Another study by Return Path found that email authentication increased inbox placement by as much as 10%. As a result, the study suggested companies with no authentication are at a higher risk of having their emails marked as spam, negatively affecting deliverability.
In conclusion, email authentication is an essential tool for any business that wants to ensure its emails are reaching its subscribers' inboxes. It ensures the trustworthiness of the sender's identity and reduces the sender's risk of being blacklisted. Authenticated emails have a better chance of reaching the recipient's inbox, thereby improving your email deliverability rate. To avoid spam filters, it is vital to implement email authentication protocols such as DMARC, DKIM, SPF, and BIMI. By doing so, businesses can establish trust with their subscribers and benefit from an increased ROI from email marketing campaigns.
