Hi Greg,
Just wanted to follow up here and say that, after talking to my colleague, there is nothing wrong with using the `sendMessage` function. The `nlb_sendMessage` was created specifically for newsletters but the sendMessage function has many other features you can use. There aren't any disadvantages to using it, just advantages really. Check the file lib/mail_functions.php around line 43 for all the features of the sendMessage function.
Please let us know if you have any further questions.
