Ctx: WhatsApp Chat + Marketing

Despite a fairly difficult start with CTX (Meta banned my account just after the integration, not CTX fault ..) the support team has been very responsive and helped me through the process of setting up and fixing a few things here and there. I haven't yet seen the return of the app, it's only been a couple of weeks, but I have friends who have been using for over a year and can't recommend enough. Give it a go, I am sure you won't be disappointed.
