Pay per email! Good at selling their product but then TERRIBLE support - They are reselling a product from another country so do not have database access, etc. Any group updates or changes require downloading your entire database to excel, copy-pasting the columns into to a separate "import" spreadsheet and then re-uploading! I think the fact the export spreadsheet is not in the correct format to be used as the import spreadsheet is a great example of how badly developed this CRM is. They need a support dept that can complete mass actions requests since users cannot perform these actions themselves on more than 1 contact at a time. *EDIT: I note they made reference to not wanting to stuff up the Match Alerts process currently in place so I did some investigation and it is already broken from several months ago and not sending(something they were apparently unaware of despite investigating my file and citing the importance of working match alerts as their reason for inaction in the below reply). Like I said support do not help, and management are good at selling the product but they have no idea what is going on so I think they must be resellers of some international CRM product. The web UI lacks the ability to select more than 5000 results from a contact search, etc. The support department cannot action any group updates or changes. You must do it yourself via the export/import process described above or pay a staffmember to update manually via the web page. If you are looking for a CRM, I would shop around for an alternative...
