Paid plans start at $99/mo. There's also a free plan.
Sinch has a free Functions entry point, but the lowest published monthly Engage plan is Basics at $99/month. Higher Engage tiers run $249 to $2,399/month, with monthly SMS limits from 3,000 to 150,000. API messaging and voice are usage-based, and Sinch does not publish per-message, per-minute or Functions compute rates. Engage advertises 16% savings with annual billing, but not the annual dollar prices. So $99 is a floor, not a full budget.

04Is Sinch worth the money?
Sinch is worth considering if you need messaging alongside voice, email, verification or ready-made communication tools. The published Engage grid gives buyers concrete monthly SMS allowances, but API messaging, voice and Functions costs remain hard to forecast because rates are not published. The $99 Basics tier is a clear entry price, not necessarily the total cost of sending messages. Compare the plan’s included volume with your needs, then ask Sinch for usage and annual prices before committing.
Sinch pricing FAQ
What is the cheapest platform for SMS marketing?
Among Sinch’s listed monthly plans, Basics is the cheapest at $99/month and includes 3,000 SMS and one user. Functions starts free, but Sinch bills compute time and API SMS by usage; its rates aren’t published, so free entry does not mean free ongoing SMS.
Is Sinch a legit company?
The published material identifies Sinch as a communications infrastructure provider with messaging, voice, email and verification APIs, plus ready-made business applications. That does not independently verify corporate standing or service quality. Check current company records and customer references rather than treating a pricing page as proof.
Is Sinch a texting app?
Sinch is described as communications infrastructure, including APIs for SMS, RCS and WhatsApp, as well as ready-made business applications. It is not presented here as a consumer texting app. Its listed Engage plans focus on business SMS automation, contacts and team messaging.
Who owns Sinch?
Ownership details are not included in the published Sinch product and pricing information, so we can’t confirm who owns the company from these details. Check Sinch’s current corporate materials or official company filings for an up-to-date ownership answer.
