Best Sinch alternatives in 2026

Sinch has the widest direct carrier network here, 190+ countries, but received texts cost the same as sent ones, email lives in separate products (Mailgun and Mailjet) and its MCP server is a local preview. The best Sinch alternative for apps that send both is Unitpost: email and SMS on one API and bill. Telnyx and Bird cost the least per US text.

Updated November 2, 2026. We make Unitpost, and it is on this list. Every score has a reason and the weights are published below, so you can re-rank it for your own needs. How we scored

Why teams look for a Sinch alternative

Received texts are charged at the sending rate.
Email is Mailgun or Mailjet, separate products with separate accounts.
The MCP server is a local developer preview.

When Sinch is still the better choice

You need very wide country coverage or short codes
You want flash-call or data verification
You need RCS or WhatsApp alongside SMS

Moving your texting off Sinch

There is no one-key import from Sinch, and Unitpost doesn't port numbers in. You get new numbers or Sender IDs, and in the US you register your brand and campaign with Unitpost (10DLC or toll-free verification), which the carriers review before you can send
Import your contacts with their phone numbers and record the consent you already hold, opt-outs included, so nobody who texted STOP to your Sinch number hears from the new one
Then change the send call to POST /sms and point delivery callbacks at Unitpost webhooks (sms.sent, sms.delivered, sms.failed; replies arrive as sms.received). Keep Sinch sending until the new sender is approved and live

How we scored

This list is for teams texting customers through Sinch who are weighing a switch. What matters to them: the real US price with carrier fees, help with registration and consent, a clean API, reach, and whether email and AI agents fit in the same place.

US price (25%). The price of a US text, with carrier fees and number rental counted, at the entry tier.
Developer experience (20%). A clear REST API, current SDKs, readable errors and docs.
Registration and consent (20%). Help with 10DLC or toll-free registration, consent records and STOP handling built in.
Global reach (15%). Countries you can text from one account, with local senders where they're required.
Email too (10%). Email in the same product, on the same contacts, key and bill.
AI agents (10%). An official MCP server or agent tooling that sends texts through the same checks as the API.

Each product gets 1 to 5 per criterion, from its own pricing and docs pages. The total is the weighted mean, so changing a weight re-ranks the list.
