SafetyMails' MailTester allows you to analyze an email campaign and identify areas that require attention before using it in your mailings. The tool checks various aspects of the message, such as authentication settings, HTML code, anti-spam and phishing indicators, as well as other technical characteristics of the email.
At the end of the test, your campaign receives a score from 0 to 100 and a detailed report with the findings, making it easier to identify potential adjustments.
Important: Each email sent for analysis to MailTester uses 100 credits from your SafetyMails account.
How to Use MailTester
In the side menu of the SafetyMails platform, go to MailTester. On the home screen, you’ll find a unique email address for running the test.
Click “Copy Address,” and then, using the email marketing, automation, or CRM tool you normally use, send the campaign you want to analyze to that email address.
It’s important to send the email using the same tool you’ll use for your actual campaigns. This way, MailTester can analyze the received message while also taking into account the information and settings used during the send.
As soon as the email is received, the analysis will start automatically. The test box will continue to monitor for receipt while you send the email.

Understanding the MailTester Report

Email Preview
MailTester allows you to view the received message to check how the campaign content was processed. You can also view various details related to the message's structure, including its source code and header.
This information is especially useful for investigating technical elements in the email and identifying potential issues in the campaign's setup.

DNS and Authentication Settings

- SPF
- DKIM
- DMARC
- ARC
- MX
- SOA
Analysis with SpamAssassin
MailTester also displays the results of the analysis performed by SpamAssassin, showing the rules identified in the message and the score associated with each one.
This way, in addition to knowing which elements require attention, you can see which characteristics of the message were identified by the antispam engine.

These metrics help identify aspects of the campaign that can be revised before sending out new emails.

How to Interpret the Scores
The score from 0 to 100 serves as a summary of the results found during the test. The more issues or relevant indicators that are identified, the greater the need to review the report and address the highlighted points.
The score should be used in conjunction with the detailed information in the report. It does not guarantee or predict that the email will reach the inbox, as campaign delivery also depends on other factors not covered by this test.
After making the necessary adjustments, you can resubmit the campaign to MailTester and run a new analysis to check the updated results. Keep in mind that each new test uses 100 credits.
