SendAPI
One API and one dashboard to send WhatsApp messages, SMS and transactional email — instead of juggling Twilio, a separate email provider and the WhatsApp Business API separately.

Description
If you've ever built a product that needs to message users, you know the annoying part isn't sending one message — it's that WhatsApp, SMS and email each come from a different provider, with a different API, a different dashboard and a different invoice. SendAPI's whole pitch is collapsing that into one account: one API key, one dashboard, and a single bill that covers all three channels.
Under the hood it's a fairly complete transactional messaging stack: WhatsApp Business API with template messages and interactive buttons, global SMS/OTP delivery, and transactional email with tracking plus SPF/DKIM/DMARC domain authentication and dedicated IPs. It ships official SDKs for Node.js/TypeScript, Python, PHP and Go, and the company is an official Meta Business Partner, which matters if you're worried about WhatsApp API access getting revoked. Pricing is tiered by volume: Starter at $9.99/month (5K emails, 1 WhatsApp session), Growth at $29.99/month (25K emails, 3 sessions), Business at $79.99/month (100K emails, 10 sessions), and custom Enterprise pricing above that — with a 7-day free trial that doesn't require a credit card.
💬 Our review
The short version: SendAPI is a reasonable pick if you're a small team that doesn't want to integrate and pay for three separate messaging vendors, but the pricing tiers are stingy at the low end and it's a much smaller, less battle-tested company than the alternatives.
Compared to Twilio (SMS/WhatsApp) plus a dedicated email provider like Postmark or Resend, SendAPI is cheaper to start and genuinely simpler to integrate — one dashboard beats three. But Twilio has a decade of reliability data, far deeper documentation, and enterprise-grade delivery infrastructure that a smaller unified player can't match yet; if uptime and deliverability at scale are non-negotiable, that track record is worth paying for separately. The volume caps are also tight: 5K emails and one WhatsApp session on the Starter tier will be outgrown quickly by anything beyond a side project. Good fit for an early-stage startup consolidating vendor sprawl; not yet a serious Twilio replacement for anything mission-critical.
