EasyCoexistence vs Sinch
Sinch is an enterprise communications platform that resells WhatsApp alongside SMS, voice and other channels, charging its own per-message fee on top of Meta's under each customer's agreement. EasyCoexistence connects a WhatsApp Business app number to Meta's Cloud API through Coexistence, self-serve, for a flat fee per number, while Meta bills its messages to you directly.
What each message costs
The difference is whether a second fee sits on every message.
Sinch: Two layers on every message: Meta's fee by category and country, and a Sinch fee for platform access and per-message service, set by your agreement with Sinch rather than a public rate card.
EasyCoexistence: One layer. Meta bills its fees to your own WhatsApp Business Account, and we never mark them up. Our charge is US$ 9 per connected number per month, falling to US$ 1 as you add numbers, whatever the traffic.
Which numbers each one is built for
Most small businesses already answer customers on the WhatsApp Business app. That number is the one that matters.
Sinch: The Sinch Engage Classic setup guide asks for a number that can receive international SMS or calls and is not connected to any WhatsApp account. Their onboarding articles do not describe a Coexistence path.
EasyCoexistence: The number already on the WhatsApp Business app, connected through Coexistence. Chats, history and the app on the phone stay, and the Cloud API runs on the same number.
How you get started
One route goes through a sales agreement, the other through a signup page.
Sinch: Embedded Signup on the Sinch Build Dashboard is, in their words, only available to direct enterprise clients at this time, and pricing depends on your agreement.
EasyCoexistence: Self-serve Meta Embedded Signup in about two minutes, with the first 3 days free. The app needs version 2.24.17 or later and recent real activity.
Which one to choose
An enterprise buying SMS, voice and WhatsApp from one contract under negotiated terms is buying CPaaS, a different purchase from a WhatsApp connection.
A business whose customers already write to its WhatsApp Business app, or an agency connecting those numbers for clients, needs Coexistence, a published price and no fee stacked on each message. EasyCoexistence is built for exactly that, with webhooks routed by Meta to your own system and an MCP server for AI assistants.
