Users cannot receive the sent email

There could be a couple places email is getting dropped. The most likely culprit is your hosting provider imposes some sort of limit on the number of outgoing emails you can send or the number of recipients who can be placed in the BCC header.

Email Users puts all of the recipients into the BCC header so other recipients cannot see who else is receiving the email.

Some questions:

1. Are you able to send an email to a single recipient?
2. Are you able to send an email to a small number, say 2-3, recipients?

How many users

Hi Mike,

thanks for replying. About your questions:

1. Yes i am able to send an email to single recipient but until 10 i think.

2. Yes, i am able to send an email to 3 recipients. I have tried it and it works.

I have 191 Users.

Thanks again for replying.

Have you tried setting your BCC limit to 10 and see if you are able to send to your group?

Hi Mike,

what do you mean with BBC Limit? ?? Sorry i am not a profi Website developer.

Thanks

Email Users has a setting, actually, it has a lot of settings, one of which is the BCC limit. The BCC limit caps the number of email addresses which will be placed in the BCC header when an email is sent.

By default, without a BCC limit set, Email Users will attempt to put all of the target recipients into a single BCC header. If you have a lot of users, this can be a problem and many hosting providers, for spam prevention purposes, also limit the number of addresses which appear in the BCC header.

For examples, you stated above you have 191 users. If you set the BCC limit to 25 and send a message to all 191 users, Email Users will send 8 separate email messages (Users 1-25, 26-50, 51-75, 76-100, 101-125, 126-150, 151-175, 176-191).

The BCC limit setting is one of the many settings on the Email Users settings page: Dashboard > Settings > Email Users

Hi Mike,

thanks so much for your explaination. I have tried it now by changing the BBC limit fron none to 10 but nothing happens. The same problem, the message appears, that the mail has been sent successfully to the group but the Users belonging to this group have not received it. However, when i send an email to the group Administrator, which has only 8 Users, it works well.

Thanks again for helping me.

I would check with your hosting provider to see if there is a limit to the number of addresses which can appear in a BCC header. It sort of sounds like there is if 8 works but 10 does not.

The other thing to do is use debug mode to see if the email headers match what you expect them to be. When in debug mode, no mail is actually sent but instead, a bunch of information is displayed on the Dashboard. You can actually see what the content of the BCC header will be and you can check to make sure the addresses you expect are actually included.

Make sure you turn debug off when you’re done as it can/will affect other parts of WordPress if you leave it on (e.g. comment notification).

Hi Mike,

i have enabled the debug mode and got the following message on the top the frontend of my Website. I do not know if this message is coming from Email Users ?? :

Debug Mode On
Array ( [error] => [m] => [p] => 5 [post_parent] => [subpost] => [subpost_id] => [attachment] => [attachment_id] => 0 [name] => [static] => [pagename] => [page_id] => 5 [second] => [minute] => [hour] => [day] => 0 [monthnum] => 0 [year] => 0 [w] => 0 [category_name] => [tag] => [cat] => [tag_id] => [author] => [author_name] => [feed] => [tb] => [paged] => 0 [comments_popup] => [meta_key] => [meta_value] => [preview] => [s] => [sentence] => [fields] => [menu_order] => [category__in] => Array ( ) [category__not_in] => Array ( ) [category__and] => Array ( ) [post__in] => Array ( ) [post__not_in] => Array ( ) [tag__in] => Array ( ) [tag__not_in] => Array ( ) [tag__and] => Array ( ) [tag_slug__in] => Array ( ) [tag_slug__and] => Array ( ) [post_parent__in] => Array ( ) [post_parent__not_in] => Array ( ) [author__in] => Array ( ) [author__not_in] => Array ( ) [ignore_sticky_posts] => [suppress_filters] => [cache_results] => 1 [update_post_term_cache] => 1 [update_post_meta_cache] => 1 [post_type] => [posts_per_page] => 10 [nopaging] => [comments_per_page] => 50 [no_found_rows] => [order] => DESC )

That doesn’t look right.

It should look something like this when you enable debug:

Is this still a problem?

Hi Mike,

i contacted my web Hosting and there is a Limit for sending emails. But when sending with the plugin “User Messages”, it works very well but i cannot attach an Image with this plugin. May be, do you know how to do that?

Thanks so much

I do not – I am not familiar with User Messages at all other than it was written by the same author who originally wrote Email Users.

Hi, I have installed email users, but it does not send. Not even to a single recipient. WP does send emails via contact form just fine.
I did send test message to myself and to my other email. none arrives.
Plugin says it was send . nothing arives.

I also installed the groups plugin from the same publisher and it did not work at all. I got an error message : You are not allowed to manage items.
????????? as an admin?
I could not fix either issue.
The website works fine, has few plugins theme customizr run on childtheme.

Never had a problem and now this. I wonder.

I have nothing to do with Groups so it couldn’t come from the same publisher as Email Users.

As for not receiving email, do you receive email from your site for comment notifications or user registrations? Email Users uses the same wp_mail() that WordPress uses for those actions.

When a plugin doesn’t work as expected 9 times out of 10 there is some sort of plugin conflict going on. Figuring out which plugins are conflicting is usually a process of elimination. Temporarily disable all plugins except Email Users and see if you can send the test email. If you can, start enabling others plugins one at a time until Email Users stops working and you’ll identify which plugins are conflicting. Once we know the conflict we can figure out what to do about it.

I checked with the contact form, and I do not receive emails with it anymore as well.

The google capcha works fine and I get also the confirmation that the message went.

But I do not receive anything from the form either.
I am getting really frustrated, so much time.
