BuddyPress.org

I’m using Sendgrid plugin to send emails. It replaces the wp_mail() function included with WordPress. Also BuddyPress 2.5.2 and WordPress 4.4.2.

In the BuddyPress source code I found a filter 'bp_email_use_wp_mail', which skips BP’s email handling and instead sends everything to wp_mail() if wp_mail_content_type() has been configured for HTML, or if wp_mail() has been redeclared. That’s exactly my case (both if‘s).

So to omit using wp_mail() – which sends data in plain text only – I wrote this:

function cd_fix_bp_email_for_sendgrid( $status ) {
    return false;
}
add_filter( 'bp_email_use_wp_mail', 'cd_fix_bp_email_for_sendgrid' );

And now I’m using BuddyPress sending functionality. And not receiving emails at all.

I opened bp_send_email() function and printed debug information right before this line:

do_action( 'bp_send_email_success', $status, $email );

I see that $status is true, $email – is not good (content_html == content_plaintext).

I opened class-bp-phpmailer.php (which actually sends all the data) and printed the $phpmailer object right before return $phpmailer->Send(); call – everything is fine (template populated, content processed properly) – but no email in my inbox.

So to sum up:

1. Sendgrid redefines wp_mail(), I filtered this to use bp_email()
2. $phpmailer has proper content
3. email is not sent

Dunno what to do next to start using these cool new BuddyPress Emails 🙂
