Email verification tools to avoid being considered a spammer

When you send an e-mail, several things can happen: either the e-mail reaches the recipient’s inbox without a hitch, or the recipient doesn’t exist or no longer exists, or it is filtered by your correspondent’s anti-spam software. In an email campaign, these uncertainties can have a detrimental effect on the real impact of your campaign.

It’s therefore important to ensure the quality of your email infrastructure and the deliverability of your emails. This can be done using verification tools available on the Internet. The purpose of these tests is to validate the content of the e-mail, or to point out any inconsistencies in your e-mail architecture, so that your message is not considered spam. Here are a few free tools whose services can be used to test the deliverability of a mailing or emailing.

As the technologies and analysis systems offered by the various anti-spam testing tools are very diverse, we have rated them from 1 to 3 stars (average, good, excellent) to make your choice easier. These assessments were based on a number of essential criteria: the design or overall aesthetic appearance of the website and its ease of use, the completeness of the analysis and tests carried out, the quality of the results provided, and the ease of understanding the actions to be taken. The average of all these ratings forms the tool’s overall score.

1 – The Mail Tester tool

This free tool increases email deliverability and reduces the number of spam rejections. Easy to use, users simply post their e-mail to the address automatically generated by the tool. It’s also possible to change the destination address to a personalized one, as long as you keep the “@mail-tester.com” domain name.

In addition to the performance score, the Mail Tester tool offers a very well broken-down result: display of e-mail in various formats, verification with an open source spam filter, DKIM signature validation check, comparison of server IP address with notorious blacklist database, search for possible errors and broken links in content.

5 – The Mailing Spam Check tool

The free Mailing Spam Check tool is an installation program, not an online tool like other services. This tool is free to download. As far as its use is concerned, after passing through the filters set up by several specific tests, a spam rate will be issued. A high score means that the email is highly likely to be considered spam. The score obtained, together with a report on the tests carried out, will be included in the e-mail header before dispatch.

To sum up its features, the free Mailing Spam tool allows you to check the spam rate of e-mails before they are sent, with the aim of improving their delivery. A SpamAssasin filter, a Razor engine, SURBL blacklists and spam cleaning tracks are all included in this tool.
