I am using the following code:
$message = "Hi ".$user.
",\r\rThe following names are on the guestlist for <b>".$night.
"</b> on ".$date2.":\r\r". $user ."<br>". implode(", ", $names).
"\r\rThank you for using Guestvibe.";
mail($email, "Your Guestvibe list", $message);
The carriage returns in PHP are working fine, but neither the <b> or <br> tags are coming out. Is it just my mail client (Apple Mail) playing up, or is there a fix for this?
You are sending the e-mail as text only not HTML, I believe you need to set these headers:
as in example #4 of the docs.
