Quick answer: In-app and push messages cost nearly nothing to deliver, so they’re unlimited in every plan. SMS costs real money per message, so it runs on a transparent prepaid wallet instead of being hidden in your subscription price.
How it works
Push reaches installed apps instantly; the inbox catches everyone else on next open.
SMS is the guarantee channel for members who never installed anything — spend it deliberately.
The wallet’s zero-balance rule pauses only SMS; core delivery never stops.
Frequently asked questions
Which channel should a normal notice use?
In-app + push. Reserve SMS for time-critical or low-smartphone audiences.
Is WhatsApp supported?
WhatsApp rides the same prepaid wallet as it rolls out via business providers.
