What mailer script are you recommending?

We are recommending to use Robert Putty's LFMVM script.

You can find more details about it at: https://theviralmailerscript.com/viralurl/

The server requirements are described on this page: https://theviralmailerscript.com/content.php?page=require

Please note that LFMVM is not the script ViralURL script is based on.

For ViralURL we use an extremely customized version of Mike Filsaime's BFM script.

A very old, not customized version the BFM is available for free at: https://franklik.es/BFM232

Now, the downside with the BFM script is that it comes with no support. LFMVM, on the other hand, is modular and has many optional available modules to customize it.
