BuddyPress.org

I was using this plugin (https://wordpress.org/plugins/email-users/)to send mail updates and newsletters to users of my site, but it stopped working, I also tried this one(https://wordpress.org/support/plugin/wp-mail-smtp), yet it didn’t work. Though it has this notice;

Some plugins, like BuddyPress and Events Manager, are using own email delivery solutions. By default, this option does not block their emails, as those plugins do not use default wp_mail() function to send emails.
You will need to consult with their documentation to switch them to use default WordPress email delivery.
Test emails are allowed to be sent, regardless of this option.

Can anyone help solve this?
