I am searching for a CMS where I can flag if I had an interaction with a client and then it automatically notifies me a period of time later to remind me to contact them again. This is essentially all I need it to do.
I am currently using
HighRise, but I don't see this function. I have also been exposed to
Zoho, but it just seems too heavy.
I realise that you can achieve this same result with calendars (for example), but I am looking for a very simple and automatic way for this to happen.
