I am looking for an open source, PHP-based CRM system (or a framework). The requirements for the CRM are:
Email marketing campaign. So creating newsletter templates, defining image-tags in order to check if a user has loaded the newsletter, send newsletters, generate click-tags for specific campaigns, see results and so on …
User activity. Managing (import/export/edit) User lists with user activities, like purchased items or usage of a service like a newsletter or even app notfications …
User login in a Web portal/app. So the user should be able to login in a website portal and see some of his data.
In my search, I have looked into different "best CRM lists" and what I found were these:
Later the system will have an API and will be attached to the DB of mobile app users.
None of these systems has what I need, but at least I would like to us a framework that is best suited for my task and can be extended.
Could you please help me to find the right one?
