It starts at US$99 a month, billed annually
The Pro plan costs US$99/month if you pay a year upfront (month-to-month costs more: the stated annual discount reaches 25%). The Free plan is effectively a sandbox: 50 active contacts and a test channel.
The SleekFlow alternative with no contact counters and no dollar pricing
SleekFlow is an omnichannel suite with AI built for structured teams: prices in dollars, capped active contacts and the WhatsApp number billed separately. SendApp starts at €19/month, with zero markups on messages: Meta bills you directly.
SleekFlow is an international conversational commerce platform and official WhatsApp BSP, strong on automations (Flow Builder), AI agents and integrations like Salesforce and HubSpot. The Pro plan starts at US$99/month with annual billing and includes 500 monthly active contacts: past that threshold you need add-ons or an upgrade to Premium (US$299/month). On top of that come US$15/month for every hosted WhatsApp number and template messages billed from their own rate card, which by their own admission can differ from Meta rates due to currency exchange and gateway fees. Data verified in June 2026 on the public pages.

Where SleekFlow makes you pay more (or holds you back)
Active contacts are capped (MAC)
Pro includes 500 active contacts per month, expandable to 2,000 with add-ons; beyond that you have to move to Premium (US$299/month, 1,000 MAC, expandable to 12,000). Every customer you have a two-way exchange with consumes quota.
WhatsApp number and messages billed separately
Every hosted WhatsApp number costs US$15/month on paid plans, and templates are billed from SleekFlow's rate card: their own calculator warns that rates can differ from Meta's due to currency exchange and gateway fees.
Dollar pricing and paid premium onboarding
Even on the Italian page, prices are in USD, with the exchange-rate risk on you. Dedicated 1:1 onboarding costs a one-off US$499 and dedicated consulting US$499/month.

Why people who compare choose SendApp
Pay in euros, at a fifth of the entry price

No active-contact counters
On SleekFlow, every contact you exchange messages with eats into your monthly MAC allowance (500 included on Pro). With SendApp you never have to count who writes to you to stay within your plan.
Zero markups on messages
With SendApp Official, WhatsApp conversations are billed to you by Meta directly, at Meta's own rates. No middleman rate card, no US$15/month for the number.
Start even without Meta verification
