What Zenvia is for

Zenvia is a Brazilian company that sends SMS, official WhatsApp, RCS and email for your app, billed in reais. You buy a prepaid message package each month and get local support, instead of dealing with Meta and the carriers yourself.

How it plugs into your product

  1. 1Sign up on a software plan (Starter is free for 1 user) and pick a monthly message package from R$100.
  2. 2To turn on WhatsApp, connect your Meta business account; Meta still verifies the business and approves each template.
  3. 3Send messages through Zenvia's API from your server, or from its panel if no one on the team codes.
  4. 4Set a webhook so your app receives replies and delivery status.

Does it fit your idea?

It fits if

  • A B2B SaaS in Brazil that wants SMS and WhatsApp billed in reais, on a CNPJ contract, with support in Portuguese.
  • A product that sends a lot of SMS, like codes for an older audience, where R$0.07 to R$0.10 per SMS beats dollar pricing.
  • A team where support people answer WhatsApp and email from Zenvia's panel, without building an inbox.

Look elsewhere if

  • You only send a few hundred WhatsApp reminders a month: going straight to Meta costs a fraction of R$0.55 per template.
  • You sell mostly outside Brazil: Twilio covers more countries in one account.
  • You're still validating the idea and can't commit to a monthly package plus a R$649 activation fee.

What people only find out after building

Read this before you build on it. Each item links to the official page that says so.

  • Turning on WhatsApp or RCS costs R$649 in the first month on the Starter and Specialist plans, even though the Starter plan itself is free.

  • A WhatsApp template costs R$0.47 to R$0.55 depending on the package, while Meta charges R$0.035 for a utility message sent directly.

  • There's no lock-in, but you must cancel at least 20 days before your next invoice is issued, or you pay one more month.

  • Even through Zenvia, a new business can only start WhatsApp conversations with 250 people a day until Meta verifies it.

What it costs in practice

SaaS sending 2,000 WhatsApp reminders: the R$1,000 package covers 2,041 templates at R$0.49, so R$1,000/month plus R$649 once to activate WhatsApp. Straight from Meta the same reminders cost about R$70. Estimated.
