Association seeks address management

We are an association and are looking for address management software for our current 1,500 addresses and contacts.

The solution should meet the following requirements:

• Import and export contacts from MS Outlook with categories
• Create and manage contacts in distribution lists
• A master address with many contacts that are assigned to many distribution lists (categories)
• Further processing of serial emails
• Form letters
• Address labels
• Participant lists in MS Word
• Personalized newsletters
• Offline work must be possible (in folders created in MS Outlook)
• Network-compatible (5 users)
• Local installation preferred due to offline function – additional cloud/VPN for mobile work and home office
• Unlimited email attachments possible?
• Webex calendar entry in MS Outlook still possible
• Is it possible to store sent emails on the server?

Five software workstations are planned. Work is done on MS Windows computers, as well as Android smartphones and iPhones.
