BuddyPress.org

Try mailgun, easy to set up and the free plan will be enough.

okay got it, you can add following codes inside
bp-custom.php or child theme functions.php to override
add_filter('bp_email_use_wp_mail', '__return_true');

I found a way to resolve this problem using a mixture of ideas others have shared elsewhere. I’ve put the details in a blog post here. In summary, what worked for me was the following in the bp-custom.php file:

// Set BP to use wp_mail
add_filter( 'bp_email_use_wp_mail', '__return_true' );
 
// Set messages to HTML
remove_filter( 'wp_mail_content_type', 'set_html_content_type' );
add_filter( 'wp_mail_content_type', 'set_html_content_type' );
function set_html_content_type() {
    return 'text/html';
}
 
// Use HTML template
add_filter( 'bp_email_get_content_plaintext', 'get_bp_email_content_plaintext', 10, 4 );
function get_bp_email_content_plaintext( $content = '', $property = 'content_plaintext', $transform = 'replace-tokens', $bp_email ) {
    if ( ! did_action( 'bp_send_email' ) ) {
        return $content;
    }
    return $bp_email->get_template( 'add-content' );
}
//Optionally remove the filter above after it's run
remove_filter('wp_mail','redirect_mails',20);
 
// Optionally change your email address
add_filter('wp_mail_from','noreply_from');
function noreply_from($from) {
  return 'noreply@YOUR_DOMAIN.org'; //Replace 'YOUR_DOMAIN.org' with email address
}

// Optionally change your from name
add_filter('wp_mail_from_name','noreply_from_name');
function noreply_from_name($name) {
    return 'YOUR_DOMAIN No-Reply'; //Replace 'YOUR_DOMAIN No-Reply' with the from name
}

@alwaysalready Thank you so much!!!!!
Your solution sorted everything. I so appreciate it!!!!!!!!!!!!!!!

In case it is interesting to anyone, to try fix this before coming to this thread, I:
1. installed “Check Email” to see if there was a problem sending emails from my site (there wasn’t)
2. installed “WP Mail SMTP”, setting up SMTP with all its complications in case it was some sort of spam issue (it wasn’t)
3. discovered using the above that the registration emails were being bounced with the error message “Diagnostic-Code: smtp; 550 Messages should have one or no To headers, not 2.” When I looked at the headers, sure enough, there were two “To: destination-email-address” lines in the header.
4. Deactivated BuddyPress. Found that registration emails successfully went through.
5. Finally came here, having found out that BuddyPress was definitely the culprit.

All this has been quite stressful, it is the first website I’ve ever set up.

Thank you @nqui and @coolhunt. Glad it’s been helpful. @shanebp, I’ll look into adding it to the codex. Thank you for the suggestion.

This works really well. Thank you so much!

Hi drstrats,

Greetings! I understand the challenge you’re facing with BuddyPress email notifications ending up in the spam folder. To resolve this issue, follow these steps:

1. BuddyPress SMTP Settings:
Ensure that BuddyPress is configured to use SMTP for sending emails. Navigate to the BuddyPress settings, and look for the email configuration section. You might find options to input SMTP details like server, port, username, and password. Set these up according to your email provider’s specifications.

2. WP Mail SMTP Plugin:
It’s great that you’ve installed the WP Mail SMTP plugin. To make sure it integrates with BuddyPress, go to the WP Mail SMTP settings. You’ll find an option to enable SMTP for BuddyPress emails. Ensure it’s checked, and save the settings.

3. Testing:
After configuring the above settings, send a test email through BuddyPress. Check the spam folder and see if the issue persists. Sometimes, it might take a little time for the changes to take effect.

If the problem continues, consider reaching out to your hosting provider to verify if there are any server-specific configurations affecting email delivery.

Hi,
Have you tried checking your SMTP settings in BuddyPress directly? Ensure they align with the configuration in WP Mail SMTP plugin. Additionally, verify if your hosting provider has any specific requirements for SMTP setup. You may need to coordinate with them to improve email deliverability. Good luck!
