I'm wanting to offer my customers front end access to my instance of acymailing. I.e., software as a service. John Doe with ABC plumbing company should be able to set up campaigns for his company. from a bird's eye view, what steps do I need to take without having multiple joomla installations? obviously I want to be compliant with the spam laws and I want their newsletters to get through.
For my main site, I currently relay the messages through elasticemail and they come from @mymainsite.com. How can I let johm have access to the same installation, manage his own list and send from @abcplumbing.com?
