    Thank you for the great plugin!

    The form works at my site, it saves all mails etc.
    But it does not send it using the wordpress default mailing system (phpmail).

    I get the following error on top of the screen: Could not instantiate mail function.

    Whay is that?

    Thank you for helping out!

    Hi, I have this problem also. I use the WordPress setting and it sends the message, I receive the message, but in the top left hand corner of the msg sent screen it says Could not instantiate mail function.

    How do I fx?
    Nice plugin. Thx.

    I have a similar issue. All of my email settings seem to be correct.

    I have updated WP-Mail-SMTP and Subscribe2 plugins to the most recent versions.
    I have set and verified the SMTP settings in Settings > Email. Send test email works.
    I have sent Send Email Preview in Subscribe2 and it works.

    When I go to Posts > Email Subscribers and attempt to send a test message, this is what happens:
    - Select Preview – message is sent and I receive it
    - Select Send – get error message: Message failed! Check your settings and check with your hosting provider. Could not instantiate mail function.
    - None of my new post email alerts go out

    Has anyone seen this error on mailing subscribers when everything else seems to work?

    Seems like this plugin does not use the wp_mail() function or...?

    Installed SMTP plugin

    "I have a plugin that sends out emails but doesn't use SMTP. Why?"

    "Said plugin has to use the WordPress default wp_mail() function when sending emails in order for SMTP to work."

    So what does it use?

    Found the SMTP settings in the plugin. Works as promised. Rated the plugin on WP Extensions.
