Mail List - SQL - Send HTML Formatted Email?

[Sketch]

Hi, currently I have a bunch of emails in a SQL database and they come out of that database into the PHP mail script and an email is sent all pretty simple, but my problem is I want to be able to send html formatted emails to everyone, but it doesn't seem to work with a lot of emails, it worked fine with hotmail but then with gmail and outlook express it didn't seem to work so what type of code do I need to put into the email so that it can sent html formatted emails to most clients? its ok if a few don't work but I would like to get as many working as possible.

Cheers

Have you tried placing a MIME type header on the e-mail message?

Assuming that you are using the mail() function of PHP, you can do this by entering Content-Type: text/html; charset=iso-8859-15 into the 4th argument. Example:

mail('your@email.com', 'Subject', 'Message', 'Content-Type: text/html; charset=iso-8859-15');

Are you using a different method of sending the e-mail?
