It starts at €299 a month
The Boost plan costs €299/month with an annual commitment (€349 month-to-month), and there's no free plan: just the trial. That's more than fifteen times SendApp's entry price.
The Trengo alternative that starts at 19 euros, not 299
Trengo is an excellent omnichannel inbox for structured support teams: from €299/month with capped conversations, an AI surcharge and broadcasting as an add-on. SendApp starts at €19/month with campaigns and AI included.
Trengo is a customer engagement platform and official WhatsApp partner, strong on shared inbox, built-in telephony and AI automations for medium-to-large support teams. Pricing starts at €299/month (Boost, annual billing; €349 on monthly) with 10 users and 6,000 conversations per year: extras cost €15–18 per 100, every AI-handled conversation carries a €0.25–0.30 surcharge, and Broadcasting is a paid add-on on every plan. It's a model built for support, where WhatsApp marketing is paid separately. Data verified in June 2026 on the public pages.

Where Trengo makes you pay more (or holds you back)
Conversations run on a meter
Boost includes 6,000 conversations per year (500/month on the monthly plan). A conversation is any reply within a 7-day window: past the window, the count starts again, and extras cost €15–18 per 100.
The AI carries a surcharge on every conversation
Every conversation touched by the AI (HelpMate) costs an extra €0.25–0.30, including on WhatsApp, voice and SMS. At real volumes, the automation that should be saving you money becomes a cost line that grows on its own.
Broadcasting as an add-on and extra users at list price
Campaigns (Broadcasting) are a paid add-on on every plan, Enterprise included. Users beyond the 10 included cost €25–30 each per month on Boost and €40–50 on Pro.
