Mail-Tester alternative: why MailGenius is the best

Mail-Tester has been trusted by countless professionals aiming to gauge the “spammyness” of their emails, ensuring that their messages don’t just vanish into the digital abyss. However, the world of technology is ever-changing, and with it, the tools we rely on must evolve too.

Enter MailGenius, a fresh face in the email deliverability scene, challenging the status quo. MailGenius doesn’t just stop at gauging the likelihood of an email being flagged as spam; it offers a ton of advanced features, in-depth analyses, and actionable insights that cater to the modern-day needs of email senders.

But how do these two tools stack up against each other? What makes MailGenius a formidable contender, and are there areas where Mail-Tester still shines? We’ll dive deep into the strengths, potential limitations, and unique offerings of both these tools

What is Mail-Tester?

Mail-Tester is an online tool designed to help email senders gauge the “spammyness” of their emails. Whether you’re a marketer, business owner, or individual, understanding where your email lands—in the inbox or the spam folder—is crucial. Here’s a closer look at what Mail-Tester offers:

  • Email Scanning: At its core, Mail-Tester scans your emails for potential issues that might prevent them from reaching the recipient’s inbox. By sending an email to a specific address provided by Mail-Tester, users can quickly receive a score that indicates the likelihood of their email being flagged as spam.

  • Configuration Checks: Mail-Tester evaluates various technical aspects of your emails, such as SPF, DKIM, and DMARC records, as well as the complexity of the email’s HTML. These checks ensure that your email setup adheres to best practices, increasing the chances of successful delivery.

Cons Of Mail-Tester

While Mail-Tester has been a go-to tool for many seeking insights into their email deliverability, it’s essential to recognize its limitations. As with any tool, it has its strengths, but there are areas where it may fall short. Below, we delve into some of the challenges and concerns users have expressed about Mail-Tester, providing a balanced perspective on its overall efficacy.

Accuracy Concerns

Some long-term users have noted a decline in the accuracy of Mail-Tester’s results, especially after it transitioned from a free to a paid service. A particular review on Trustpilot mentioned that the tool was “1000x more accurate and helpful when it was free.” Now, there are instances where it doesn’t load a response, and system crashes have been reported at least once a week.

Inconsistency Across Locations

Another significant concern is the inconsistency in test results across different locations. A user tested their email deliverability from three different locations and received varying scores. Such inconsistencies can lead businesses to make poor decisions based on unreliable data.

Limited Features

While Mail-Tester does a decent job at checking the “spammyness” of emails, some users feel that its features are limited. They wish for more comprehensive features similar to other tools that check more than just the spam score.
