I am using phpgw in our company to coordinate 6 offices around Asia.

We currently maintain a client database of several thousand names to which we regularly forward our company newsletter. This is currently done using a dedicated client contact database called Time&Chaos in conjunction with Express Plus, an e-mail client which allows personalised e-mails to be sent to any selection of contacts and using any fields from the contact database. I would love this feature to be available from phpgw.

Express Plus basically reads the T&C database directly and uses it as its default addressbook.

Whilst on the subject, T&C, and therefore Express Plus, use a great category system where you can mark any contact with multiple categories and then select groups based on combinations of categories, e.g. I often want people in say "Hong Kong" who are "Accountants". This is very easy to do.

Have a look at www.chaossoftware.com - you can download trial versions of the software if you want to see how this works firsthand.

Cheers,

Brett
