Is sendlz a real alternative to Sinch?

For WhatsApp, SMS and email, yes — and for voice, RCS or anything wider, no. Sinch and sendlz both provide official access to the same Meta API, so the messaging capability is identical; what differs is the commercial model. sendlz charges a flat monthly platform fee and passes Meta’s per-message rate through unchanged, with unlimited agent seats and INR invoicing with GST as standard. Where Sinch wins, the table below marks it in green rather than hiding it, and the section beneath tells you when to buy them instead. Migration takes two to five days, costs nothing, and keeps your number, your Business Manager and your quality rating.

Comparison

A Sinch alternative without committed volume contracts

Sinch is built for enterprise scale and enterprise procurement. The trade is annual commitments, negotiated rates and an account team between you and a change.

The honest version

Sinch is built for enterprise scale, and that shows in both directions. The carrier relationships are real, the throughput is real, and if you are sending across thirty countries with an in-house messaging team, Sinch is a serious answer.

What comes with it is enterprise procurement. Annual commitments, negotiated per-account rates that you cannot check against a published list, and an account team sitting between you and any change you want to make. Teams that move to sendlz from Sinch almost never cite a missing feature — they cite the four-week lead time on a rate question and the committed volume they did not hit.

The commercial model is the inverse. Our rates are published, our contract is monthly, and there is no minimum volume, because we would rather you stay because leaving is easy than because leaving is expensive. Self-serve signup to a first approved template runs about 41 hours.

Where that trade goes against us: we offer SMS, but if you need voice, or RCS in production today, we do not offer them, and if you need carrier-grade SMS across many countries you should check our coverage against your list before you sign. Three channels done properly is the whole strategy, and it is the wrong strategy for a business that needs eight.
