You have several options to determine whether your bulk message will be marked as SPAM.
The most common ways are as follows:
- The best practice is to create a list of test recipients and send bulk messages to them before you dispatch your message to all recipients. Always check the results of the test delivery and you will immediately find out not only what your SPAM score is, but also whether it is displayed correctly with the given email provider.
Email addresses of your test recipients should be hosted on on different domains – gmail.com, seznam.cz, hotmail.com, etc., in order to cover the largest possible spectrum of the most common mailbox providers.
- There are a number of services on the Internet that you can use to check whether your message has ended up as junk mail (SPAM). Just search for spam score checker, e.g. https://www.mail-tester.com/ and follow the instructions on the website.
