Newsletter not sending with WP 3.4.1 and Subscribe2 8.4

@danielstrietzel,

Have you set the number of recipients per email to 1 in Subscribe2->Settings?

Ask your hosting provider again about their emailing restrictions and limitations for web server generated emails.

The number of recipients per mail is set to 0.

one.com says it’s unlimited for email addresses on the domain.

One.com says it should work fine.

But the plugin should use mailout.one.com as the host. Which source-file can I edit to set the mail settings such as mailout.one.com, port 25 and the username?

One.com says: “These settings are required for the PHP mail function to work on our serves”.

@danielstrietzel,

You need another plugin for that rather than editing source files. By default Subscribe2 uses the WordPress core wp_mail() function which in turn uses the PHPMailer class and that in turn uses the PHP mail() function.

This can be plugged to channel your outgoing emails via SMTP using the WP Mail SMTP plugin.

Ok, I installed this plugin and it works with the test mails inside WP Mail SMTP.

Is there a way to tell Subscribe2 to use settings from WP Mail SMTP? Subscribe2 looks good when trying to send a Preview, but it never comes to my mailbox. And when I try to “Send an email to subscribers” I get: “Could not instantiate mail function.”

@danielstrietzel,

WP Mail SMTP plugs into the core wp_mail() function making a permanent change so Subscribe2 will automatically use it.

Di you set the number of recipients per email to 1 in Subscribe2->Settings yet? That is still a change worth making and it may help in this instance.

Wow @mattyrob

I didn’t understand you that you mean I rather should have this set to “1”.. sorry! But it works with that!

Without the WP Mail SMTP-plugin, and only with the number of recipients per email changed to 1, the “Resend Digest” works!

Now I think, it also will send the next newsletter next week automatically! Cool! ??

@danielstrietzel,

If you have that setting as 0 then the email notification is sent TO the SENDER with the other recipients in the BCC (Blind Carbon Copy) header. While this is an efficient was of sending the email it also makes it look very much like a spam email.

Changing the setting to 1 sends individual emails to each of your recipients which looks a lot less like spam and generally works a whole lot better on shared servers.

Okay, I have 1900 subscribers and now notification is not working… what do I do?

@sharijstauch,

1/ Change the number of recipients per email to 1 in Subscribe2->Settings?
2/ Make sure you are sending emails from an address that is on-domain with your blog. (Search the forum, there are lots of posts about this already)
3/ Make sure the email address you are using in step 2 is a real address that actually exists on your mail server
4/ Ask your hosting provider about their emailing policies, limitations and restrictions and how you can ensure that sending to 1900 recipients doesn’t breach these limits. (For example you may need to stage the sending in batches)
