The $79 plan can't do marketing
Starter includes no broadcasts, workflows or AI agents. For a WhatsApp campaign you need the $159/month Growth plan.
The power of a conversational suite, sized for SMBs
Respond.io starts at $79/month without broadcasts and charges for active contacts. SendApp starts at €19 with campaigns and AI included.
Respond.io is an excellent omnichannel platform for the international mid-market. The problem is the bill: the entry plan includes neither broadcasts nor automations, and beyond 1,000 monthly active contacts you pay as you go.
Comparison based on Respond.io's public pricing and pages as of June 2026. Prices may change: always check the provider's website.
Where Respond.io shows its limits
Active contacts are pay-as-you-go
Beyond the 1,000 monthly active contacts included, you pay $12–15 per extra 100: an e-commerce store with 5,000 active contacts pays about $639/month.
Italian as an afterthought
Partial localization, prices in dollars only, no Italian-language support available.
A trial without the main feature
The 7-day trial excludes broadcasts: you can't test the very feature you're evaluating it for.

Three things you pay extra for elsewhere
Not a promotion: they sit inside every SendApp Agent plan, starting with Professional at €19/month.
Support is included, not a tier you buy
There is no separate support plan in the SendApp price list: support is included in every plan, from Professional at €19/month. There is no "serious" support level that costs more.
AI is in the plan, not an add-on
The AI chatbot you train on your own content is included in every Agent plan: 1 AI account on Professional, 5 on Business, up to 30 on Platinum. No module to switch on, no per-flow fee.
Zero activation costs
No setup fee and no dedicated number to pay for on the side: you connect the number you already use and start. The listed subscription is everything you pay SendApp — Meta’s rates, where they apply, are billed by Meta with no markup.
Why people who compare choose SendApp
Costs that don't explode as you grow
No active-contact fees: plans have clear limits, and the €49 Business plan covers 5,000 contacts and 50,000 messages.
Everything on the official API
SendApp puts AI, CRM, campaigns and multichannel on top of Meta’s official API with guided onboarding; Respond.io stays a more technical inbox.
Vertical features ready to go
Calendar with reminders, bookings with Google Calendar, loyalty and reviews: on Respond.io you'd have to build them as workflows.
