I created the newsletter plugin for WordPress "MailPoet"Plugin for Joomla"AcyMailing · acySMSIt is said that it is a team making a cheap, simple and effective discrimination of whether the newsletter they are sending is judged as spam.

The usage method is very simple, only sending mail to the e-mail address displayed when accessing the site. At this time, please leave the page open.


I will try out the Gmail address. Because it is a spam judgment, please put something in the subject and body. If you send e-mails only from textbooks, only sentences, if you attach images, attach something images, if you send a link with a lot of links in the text of the e-mail, by doing the same Accurate judgment is done.


After sending mail, return to the browser and click "THEN CHECK YOUR SCORE".

Whether or not the sending server is proper.


Whether the content of the message is safe. The content of this message was 227 bytes when HTML mail was sent, 75% was sentences. In other words, it is judged that it is a safe e-mail that is not an enumeration of meaningless links.


Check with 24 major blacklists to see if the IP of the server is blacklisted.


Whether the link included in the content of the message is correct or not.

It was -1.3 points by SpamAssassin that was a big minus point. If this goes to the -5th point it will be judged as spam.
