Hi @shmk
It’s definitely possible. BuddyPress uses the wp_mail() function to send emails. By default, it uses text/plain as the content type which doesn’t allow HTML. The good news is you can change this. For example:
function set_content_type( $content_type ) {
return 'text/html';
}
add_filter( 'wp_mail_content_type', 'set_content_type' );

Thanks @henrywright,
I’ve added the filter just before sending the mail and I immediatly remove it on bp_core_sent_user_validation_email to avoid problem on other WordPress mail that needs text/plain.
I’ve also found in the code inside bp_core_signup_send_validation_email( $user_id, $user_email, $key ) function these three hooks that I used to change the message as needed by my website:
$to = apply_filters( 'bp_core_signup_send_validation_email_to', $user_email, $user_id );
$subject = apply_filters( 'bp_core_signup_send_validation_email_subject', $subject, $user_id );
$message = apply_filters( 'bp_core_signup_send_validation_email_message', $message, $user_id, $activate_url );
Yeah – those are the hooks that’ll let you filter the recipient, subject, body – with your HTML 🙂
Just a note: in BuddyPress bp_core_signup_send_validation_email function wp_mail is called only with the required parameters wp_mail( $to, $subject, $message ), but the function could accept also two optional parameters wp_mail( $to, $subject, $message, $headers, $attachments ).
So if you want to edit also the headers and/or attachments you have to edit the BP core file adding the parameters and the corresponding filters.

There is a way around that (you don’t have to edit core files).
Step 1: Filter bp_core_signup_send_validation_email_to so the default activation email isn’t sent
function filter_bp_core_signup_send_validation_email_to( $user_email, $user_id ) {
$user_email = '';
return $user_email;
}
add_filter( 'bp_core_signup_send_validation_email_to', 'filter_bp_core_signup_send_validation_email_to', 10, 2 );
Step 2: Send your own activation email
function my_custom_activation_email( $subject, $message, $user_id, $user_email, $key ) {
// Create your $headers and $attachments here
// Send the email.
wp_mail( $user_email, $subject, $message, $headers, $attachments );
}
add_action( 'bp_core_sent_user_validation_email', 'my_custom_activation_email', 10, 5 );
Notes: I haven’t tested
I have used Henry’s method to customize the activation link email, but now I want to tweak the registration email. That’s the email that goes out after the user clicks on the link. How can I filter that?
Well, I kept searching and found the solution to my problem. Check out this post on StackExchange:

It worked like a charm for me.
