According to research by Statista, the total number of emails sent in 2022 is around 333 billion. The question here is whether these emails end up landing in the recipient’s inbox or spam folder.

The biggest issue faced by businesses in their email communication system lies in the deliverability of the email. “Email deliverability” differs from “email delivery”. Email delivery simply refers to whether an email was successfully delivered to the recipient’s mail server. It doesn’t guarantee that the email will land in the recipient’s inbox; it only means that the server accepted the email. mail deliverability refers to the likelihood of an email reaching the recipient’s inbox rather than being filtered into the spam folder or rejected altogether.

Unless problems with email deliverability are addressed appropriately, an organization’s reputation and credibility can take a hit. It can also lead to unsuccessful marketing campaigns, and email marketing investments going to waste. 

This article explains the need for email deliverability testing to maintain steady and consistent deliverability and its benefits in promoting an improved emailing experience.

What is Email Deliverability Testing?

Email deliverability testing involves identifying the various factors impacting the deliverability of sent emails. These factors must be identified to ensure the emails reach the correct receiver’s inbox.

As email has become an important part of digital communication for organizations, no one can afford to have their emails end up in spam folders or blocked out from inboxes. This has increased the need for email deliverability testing tools and methods. 

How Does Email Deliverability Testing Work

Email deliverability testing measures the probability of your email getting delivered rather than being marked as spam. Email deliverability testing involves validating the authentic emails falling into the correct address. It is also used for spam mail testing.

Email deliverability testing is done based on various factors. One of which is the authorization of emails from the receiving server. The deliverability status is also influenced by its delivery to the spam folder, inbox, or anywhere else.

Common Issues in Email Deliverability

• Inconsistent Testing Conditions

Sometimes, the testing conditions need to be more consistent. All the factors that affect the deliverability of the email are different for different email clients. Hence, one must adequately configure the testing conditions before carrying out the deliverability testing.

Implementing A/B Testing

It is a tuning test in email marketing that involves the comparison of the two different versions of an email. Both versions are slightly different and are sent to different recipients. 

This part of the testing includes the comparison of sender names, the email content, and the subject heading. It makes the senders understand which email has been better crafted and can engage the users.
