Mailing Group Listserv


The WP MailingGroup plugin allows you to run a Mailing Group, also known as a Listserv, right from your WordPress website. You can sign up your users, friends, family etc, directly from your WordPress administration area, and they can then all exchange emails via their favourite email software, no need to login to wordpress dashboard. It has very easy to use intuitive interface and advanced debugging functions. This is NOT a one-way Announcement list where only YOU can email everyone else. Its a Two-Way mailing group just like Yahoo Groups, Google Groups etc. It can be used as an alternative to php List and mailman. Its a wonderful wordpress group plugin to help you and your groups stay connected! – Premium version includes message moderation and archives.

  1. Unzip / Unrar the plugin folder and copy all the files to YOUR_SITE/wp-content/plugins/ folder.
  2. You can also use the WordPress plugin uploader to do so via Plugins > Add new
  3. Activate the plugin through the Plugins page in WordPress
  4. Add a new Mailing Group from the plugin’s control panel, inserting the relevant mail box details. Test imap connections using the button provided.
  5. After setting up a mailing group, if you want to see status of Imap/Pop3 connection or sent emails, go to troubleshooting page ans
  6. Insert the registration form shortcode on a page or widget on your website if you wish for visitors to be able to subscribe to Mailing Groups via your website:

6. Optional (for low to medium traffic websites only):
Paste the following command into the cron script manager on your server:

On some systems, you may need to use a curl function instead:
curl -s

For either function, the suggested frequency is every 2 minutes.
You will need to adjust the path according to where your WordPress installation is located. The above paths are for root level installations.

Full information on this can be found in the plugin�s General Settings > Help panel.

There are various methods to set the crons on your server. Here are a few for your reference:

From cPanel:

From Telnet / Putty / Command line (for Advanced Users):


How many subscribers can I have in the mailing group?

You can add up to 20 subscribers in ONE mailing group using the free plugin.

Emails are not being sent to mailing group members, how to know what is wrong?

The plugin has a page called ‘Troubleshooting’. This page will show you latest errors for IMAP/POP3 connection for each group and also any email sending errors.

Can I create my own customised messages to send to prospective subscribers?

Yes, you can: go to Mailing Group Manager > General Settings, and select the Custom Messages tab. There you can input your custom message (using the listed variables, if you are technical!).
You can also go to Mailing Group Manager > Subscription Requests, and click the message icon next to a subscription request. This opens up a popup window where you can type in a custom message, and check the box at the bottom that allows you to save it for repeated use.

I do not have access to cron scripts on my shared server. Can I still use the plugin?

If you do not have cron access, then you will have to rely on visitors to your site to trigger the in-built WP-cron, which checks for new messages and distributes them to the list of subscribers. For example, if you have a visitor on average every 10 minutes, then the Mailing Group messages will be received and sent every 10 minutes. If you have Cron access, you can set a higher frequency of 2 minutes to keep the Mailing Group updated more often (see Installation instructions above), but without cron access, it may just run more slowly.

I am getting strange characters and HTML tags in emails, how to fix that?

Excellent performance, excellent support

Not only the plugin works wonderfully, the support is incredibly fast and helpful. Had an issue that wasn’t even directly caused by the plugin, support promptly helped me and within a few hours everything started working again.

Unprofessional and missing major features

I had reservations after using the free version as it seemed to have a mediocre interface but it was one of only two plugins that do a ListServ via WordPress. I purchased the full version and was immediately disappointed. The user management is non-existent. Given that a ListServ is ALL about it's users this is unforgivable. If you have more than one mailing list you're in trouble. The import features lack any method to import directly to a mailing list. All imports are imported as WordPress users (which isn't great either) and are not grouped or identified in any useful way. You can only add 10 users at a time to your mailing list and if you've imported 2000 users that's 200 times you'll have to add a group of ten. If you have another mailing list - good luck figuring out which are the news ones you just imported as they're all mixed together. Worse - the author doesn't stand behind their product. They refused to refund because they claim I could evaluate everything in the free version. Of course, the free version lacks the importer completely.

Outstanding service

Premium version user here. Skype help with installation of 1-6-0 on a Saturday night at 20:30 local time for the developer. Outstanding service and great plug in Highly recommended 🙂

Outstanding Customer Service

I downloaded and installed the free app. I had trouble getting it set up on my site. I asked the man who runs my web hosting service to help. He couldn't solve the problem. So I asked Yumna, the author of the plugin to help. Yumna spent several hours with access to my site and solved all the issues. I'm so impressed that I will soon spring for the paid edition. Costumer service above and beyond. That's what you can expect from this plugin. Oh, and let me say, once setup correctly, it works wonderfully. And, it is the only plugin that gives you a true listserv on WordPress.

Great Support

WOW I love the plugin and the support person are awesome. best of luck and keep the things more better. Thanks Ilyas Yaqoob
