I would like to apologise first of all, in case if there does exist comprehensive documentation or manual of some sort for Mail Press. Because I have not been able to find one.
There are so many things that need explanation and it is frustrating to keep posting in groups for trivial matters. Such group/support forum should be for technical or difficult problems or odd things that someone tries to achieve.
Please update me if there is a manual and I will spend time studying it.
If not, I guess it is time one is written. I find this utility so useful and so powerful and it is a shame that there is no proper documentation. I wish I could help in some way.
Please do take this in a positive way. I understand everyone is busy and you are offering this plugin for free. I appreciate that. Thank you for such great tool.
