Emails not sent *only* to subscriber lists

[User]

I have been using the newsletter plugin for several months now and I have been very happy with it. I send a monthly newsletter to a small distribution (less than 100 subs). The last email I sent on January 20th worked fine. This month I built the newsletter, sent myself a preview no problem – received right away. My scheduled job to the sub list ran at 100 / hour but no emails were received (0 clicks, opens, etc..). Not in spam etc.. I duplicated the email and sent it again manually – same result. I ran the test email (Test the email delivery Check if your blog can deliver emails. Run a test.) and it worked.

I chatted with BlueHost twice. Once they said they changed setting on the backend (no change) and once they said they needed to run a scan for virus. I did find and resolve The signature SL-PHP-FILEHACKER-ioe.UNOFFICIAL ssv3_directory.php I haven’t tried to resend after resolving that issue.

I use the out of the box mail sender (no additional wp mail plugins or anything).

The send stats say 100% sent with no errors

Any ideas on why individual emails send but a small list will not?

Hello, I’m not sure if the infection you were experiencing has nothing to do with the sending issue (it might have, it really depends on what kind of malware infected your website and if you managed to completely remove it – which you might think you have, but in my experience it’s really really difficult to clean up a malware/injection without the intervention of a professional).

that being said, only logs can help understand why the actual send don’t go out. Please go to Help > Logs and let me know if you see some logs there. Also send me a screenshot of the full Help > Sending dashboard.

Thanks

Thanks for the reply. I do tend to doubt the malware had an impact but wanted to share the context from Bluehost. Bluehost did a full scan and I followed instructions on removal.

I took several screenshots and dopped them in a Google Photos album. Pls let me know what you think or if there are any other shots that would be helpful. The last mail to the sitribution list was on Jan 20. The only log update since then was a newsletter update. no emails were added since the last send.

Hello Matt,

thanks for the info. Please install Wp Mail Logging plugin as described here (https://www.thenewsletterplugin.com/documentation/troubleshooting/email-sending-issues/#wp-mail-logging) and perform a test send. Get back to me with your findings.

Thanks Michael.
I installed the plugin, duplicated the last newsletter, sent it realtime. 0 received just like before, and no log was generated. I added 3 screenshots with the log config page, log page, and updated email sent. Maybe this isn’t surprising and helps troubleshoot?

Let me know if you need anything else.

Thanks

One additional note. When I send an individual single test email it does work and log in WP Mail Logging. Added screenshots

After a few days there are many single emails sent and logged with no errors. What do you recommend for troubleshooting? The 3 areas I can think of are:

• The newsletter itself – try with a new newsletter – but need to understand what made this one fail
• The Distribution List – no new adds since the last successful send, and no errors logged
• The Plug In – The plug in was updated between sends and again once since.

Thanks

Hello Matt,

sorry for this delay. I cannot see particular errors from your screenshots, so let’s try another way. Ask your hosting provider if there’s a Smtp service included in your plan, if so, use Wp Mail Smtp and set your provider’s Smtp connection data. Then do a test send.

Given that email sending works for all other email updates I am hoping to keep the mailer set up simple as it is now. The benefits solve problems I don’t currently have (deliverability in particular).

The Newsletter plugin has been updated 2x since the 20th and of course other installed plugins have as well.

In order to test if the issue is with the newsletter, the list, or the plugin I tried these tests.

1. Created a new distribution list with only a few subscribers.
2. Duplicated a different newsletter and sent it to the limited subscriber list – Success.
3. Duplicated the newsletter that failed previously and sent it to the limited subscriber list – Success.

So I think this means either the updated to any of the plugins have resolved the issue OR there is an issue with the full list of subscribers.

Hello Matt,

did you also have the chance to try a full send?

Not yet – I send regular newsletters on the 20th of the month and wanted to avoid confusing the members with a test email. If it doesn’t send with the ful list, do you have any suggestions on where to look for troubleshooting next? Odd that there aren’t any errors on the full send.

Thanks for all your help!
Matt
