Zapext vs Zenvia: an honest comparison for WhatsApp communication
Zenvia and Zapext approach WhatsApp from opposite directions. Zenvia is a Brazilian CPaaS — mass communication over SMS, WhatsApp (official API), and email, billed per message, aimed at teams that need a multichannel API. Zapext is a Chrome extension inside WhatsApp Web, with CRM and broadcasts, and no per-message cost. If you need to send SMS and WhatsApp via API at high volume, multichannel, Zenvia is the path. If you're an SMB selling through WhatsApp Web, Zapext delivers more with less red tape.
