How can I personalize the e-mail subscribers get?

Hi,

This might not be the right place for this but I’m not hopeful the plugin’s dev will reply.

I’m using a plugin called “St Category Email Subscribe” which works great but I’d like to personalize the email people are getting. The plugin basically subscribes people to specific categories and when posts drop in the categories they get emailed.

I know it’s possible because our company’s former dev did it to one of our old wp sites but we can’t seem to find out how he did it.

Please find attached some screens of how it is atm and how we’d like it personalised.

I don’t know if anyone is familiar with this situation or has helpful input but here’s hoping! Thanks!
