Formatting text in PHP email

programming
1

I’m trying to format text that is sent in an email from PHP with something like this:


$mail = "<b>Telephone:</b>" . $telephone . "
" . "<b>Address:</b>" . $address . "
" . "<b>Enquiry:</b>" .$message; 

mail($sendTo, $subject, $mail, $headers);

It ends up looking like this: “<b>Telephone:</b> 0034*********” in the emails - it seems to be quoting the tags.

What should I be using?
