Before I jump in I have a concern or two. Currently use WinPIM and it works pretty well but I am always looking for something better. One requirement, and I do not see this in eM Client is integration with MS Word. I use WinPim (and before that Chaos Intellect and Outlook) to generate letters to clients, setting up templates that extract certain data from the contact list. Can this be done? Also, “exhaustive” to me means limited. How many fields can be added?
There are just over 80 fields available in Contacts.
eM Client does have a mass mailing feature, so you can do a mail-merge from your contact details using a mail template.
You can find more information on these in the Help File (F1), but please ask here if you need more details.
