I'm looking around for a (preferably free) "Refer a Friend" Perl script, however I have only been able to find scripts that send a text based email to the friend. I would like to be able to send a HTML based email. Bearing in mind that I know next-to-nothing about Perl at the moment (but I'm learning fast), is there anyone who could recommend a script that will do this.
The two things I looked at were: 1. Is the form configurable and reasonably attractive? 2. Does the output email "read" in such a way that recipients won't feel like they've just been spammed?
A lot of the scripts have an on-page form for your email and that of the recipient. I chose Bluesend partly because it uses a pop-up form instead of taking up so much space on my site's pages. That also allowed my to design the "recommend this site" button to match the look and feel of the rest of the site.
We are already using a slightly modified script from the BigNoseBIrd site, but the text based email looks a bit plain. However, as Rogerd points out many people dislike HTML based emails so I think I should bear this in mind.
