Large colleges can't depend on a single employee's phone that's running WhatsApp (their phone may deplete its battery power, or the employee may leave the company). WhatsApp's apps (including it's business one) don't support multiple users, analytics, integrations to other apps, or automatic group creation (as each group is capped at 250 subscribers). We integrate with their official business API to enable 100% uptime and all 3 of these features.
No - automated messaging is against the WhatsApp terms of service; however, our paid plans include the services of an account manager who will manually personalize & broadcast your message to multiple groups without any further effort on your part.
We provision a new dedicated number for your business to enable WhatsApp's official business API.
We have plugins available for Shopify, Wordpress, and other platforms that install in under a minute - no IT required.
