Hand-picked from 500+ Indian businesses already running their A2P messaging on Cubicles Coders.
We migrated 4 million monthly OTPs to Cubicles and our auth-failure tickets dropped 70% inside two weeks. Their engineering team replies on WhatsApp at midnight — no other vendor we've used does that.
The dashboard is the cleanest one we've seen in this category. Our marketing team set up the first campaign without a single ticket to engineering.
From WhatsApp to SMS to RCS — they handle it all on one invoice. The single-PO model is what convinced our finance team.
Delivery rates we'd been promised by three previous vendors finally became real numbers. Worth the migration ten times over.
