Campaigns not sending Part 2

This pertains to the same issue as seen here

When I go tp Newltters -> Subscribers in the backend the list is empty “no items found” but when I export a list there are 28 subscribers on it. Why do they not show in the admin? The ones that show in the export have user accounts.

Also we are using this plugin to Email Itthinx User Groups, we do not actually need any of the Newsletter functionality, we just want to be able to email specific Itthinx groups. So if there is an easier option please let me know.

The last post said I may need to reimport to subscribe existing users (we have 10,000). So if I get all 10k in a tab delimited txt file and import them will they retain their group status? Meaning if I then select Group A and send them a newsletter only Group A will get it?

    Hey Lawrence,

    Following-up after my try and the campaign has been sent properly.
    This is the message I’ve received: –
    If you need me to try something else, please let me know. In general though if you have a large amount of recipients for each newsletter, then it’s definitely better to use SMTP again.

    Kind regards,

    Sure, let me have another look.

    Thanks for the follow-up Lawrence.

    As it seems your site doesn’t send emails. I tried running some campaigns but the mails didn’t reach at least my own destination.
    Using the test features in Groups Newsletters, Mail Queue, Mailgun plugins gives exactly the same error, an issue with your SMTP.
    1. Groups Newsletters ->
    2. Mail Queue ->
    3. Mailgun ->
    Unless, the credentials used are not correct, then something else is wrong with your SMTP service.
    Furthermore, IMO the error 502 you have is probably related and most importantly still persists. For example, this screenshot has been taken when I was trying to deactivate Mail Queue plugin.

    If you take a closer look to the URL, you can figure out the action I took when it occured.

    Once you have a solid update, please let me know to have another look.

    Kind regards,

      Hi George, this was an issue with the staging site and mailgun. I have disabled mailgun and the emails work now.

      • George November 24, 2023 at 7:26 pm #

        Are you sure Lawrence because for the screenshots I got, in the first and second Mailgun plugin was deactivated(to avoid possible conflicts with Mail Queue, if Mailgun plugin also overrides the default wp_mail()) and for the third Mail Queue was deactivated.
        Since you’re certain about the credentials I’ll have another look.

      Okay got emails sending from /wp-admin/edit.php?post_type=story&page=groups-newsletters-settings and /wp-admin/admin.php?page=itthinx-mail-queue-settings, just had to clear some of the SMTP settings and change the From address, can you try again?

    Hey Lawrence,

    Such errors are server related, so even if I switch my browser it doesn’t automatically mean that the error is resolved. After several attempts reloading the wp-admin I managed to login again, but the HTTP authentication is still active.
    Please make sure to deactivate it and let me know.

    Kind regards,

    • Lawrence November 22, 2023 at 5:46 pm #

      Thanks George I have deactivated http auth now

    Hi Lawrence,

    Tried to access your site again but the aforementioned issue, occurs even on wp-admin page:
    Please have a look at your debug.log and also the rest of your server logs for additional info on this issue.
    Once you have an update and the site is accessible again, let me know to login.

    Kind regards,

    • Lawrence November 21, 2023 at 5:11 pm #

      I was able to replicate your issue, found the problem and fixed it (or so I thought). Still works for me. Can you please try another browser or incognito mode?

    Hi Lawrence,

    Thanks for providing access to your site.
    I had a quick look on your setup and what you should do is enable WP Debugging, because while browsing your site I got a 500 HTTP error while trying to view the Users.
    I’m expecting more errors to be logged, because the performance is pretty low at the moment.
    Also, make sure to disable the HTTP authentication, as it is known to be blocking scheduled tasks and can block the process.

    Kind regards,

      Hi George, should be working now, also I updated the admin to your email and added the below rules to wpconfig.


    • Lawrence November 21, 2023 at 5:14 pm #

      I should clarify I was able to replicate your issue the first time and fixed it. wp-admin is working for me still. No more errors int he logs.

    Hi Lawrence,

    Yes, you can create the temp admin account using the email address george at itthinx dot com.

    Hi Lawrence,

    I think it’s better if we have a look at your setup, preferably on a staging clone so that we won’t interfere with your daily operations. For the staging site it will also be useful if you enable WP debugging using the following constants on your wp-config.php file.

    Edit the file and replace

    define( 'WP_DEBUG', false );

    with these lines:

    define( 'WP_DEBUG', true );
    define( 'WP_DEBUG_LOG', true );
    define( 'WP_DEBUG_DISPLAY', false );

    As for the temporary admin account, you should use george at itthinx dot com as the email address.

    Kind regards,

      Okay I’m creating it now. Is there a way I can provide access privately?

  9. Lawrence November 15, 2023 at 7:10 pm #

    I tried with a test group of 3 users. I import them all into subscribers and confirmed they all have “Yes” in the subscriber column. 2 of the users have the Administrator role and 1 is a Student role (we have a learning management system).

    The Student received the newsletter but the 2 Admins did not.

    The campaign Status says “3 emails of 3 in this campaign have been sent. 0 are in the queue.”.

    Is there anything I can do to debug further?

    Hi Lawrence,

    The subscribers listed in Newsletters > Subscribers are those that have a subscription but not a user account. This means that your export file includes subscribers with a user account. With Groups Newsletters you can have subscribers with a user account but also without one, it is not mandatory for a subscriber to be registered on your site. This is why there is this distinction and also two different lists of subscribers.

    The only way to send massive emails to specific groups of users, is via this addon, Groups Newsletters. Once you import your subscribers, the group they belong to, won’t be affected. This process relates only to the subscription option and not the group. However, if you are in doubt, you can always try this process on a test site or use a few test accounts.
