The WhatsApp platform that finishes the sentence.
Most platforms give you a dashboard. SendyStack gives you a dashboard, an assistant that operates it, payment rails that match your country, and compliance that runs automatically — so the next step is always done, not described.
“Switched from a per-message provider — saved us $4K/month and the support is night and day.”
Marina W., Marketing Manager · PhytoLuxe
“The assistant scheduled 200 invoices to our property tenants while I was on a call. Honestly mind-blowing.”
Eliakim K., Property Manager · Alfresco Estates
“First WhatsApp tool we've used where compliance isn't a person on Slack going 'wait, can we send this?'”
Haruna H., HR Director · Dukah, Jumia
Six reasons we win
What makes SendyStack different — in plain English.
An AI assistant that actually does the work
Other tools give you a chatbot that suggests what to do. SendyStack's assistant CALLS the same tools you would: it creates broadcasts, schedules messages to specific contacts, registers templates with Meta, builds WooCommerce automations — scoped to your workspace only. You stay in conversation; it ships the action.
Compliance baked into every send
Every template draft and every API message body goes through a two-layer policy scanner before it leaves SendyStack. You don't need a separate review process — the review is the platform. We surface Meta's rejection reason verbatim when something fails so you can fix it on the first try.
Three payment rails, one checkout
Stripe Card, PayPal, and M-Pesa side by side. The right rail auto-selects from the workspace's country — M-Pesa for Kenya / East Africa, Card elsewhere. No second processor account, no Plaid integration, no manual currency math. The whole stack reads in KES, USD, or whatever your locale uses.
Industry kits, not generic templates
Property Management gets rent invoices + payment reminders + M-Pesa receipts. WooCommerce gets order-status automations + abandoned-cart broadcasts. Freelancer / Services gets unpaid invoice nudges. Each kit ships with approved Meta templates so you're sending day one — not day thirty.
Operator-first analytics
Delivery rate, read rate, replies, weekly trend, top templates — the numbers a manager actually asks about, not a 200-widget data lake. The same metrics power the in-dashboard assistant so you can ask 'how was last week?' and get a real answer.
Honest API access
Scoped server-side keys with the exact permissions your integration needs. A single REST endpoint to send a message. Webhooks signed with a shared secret. SDKs for cURL, Node, Python, PHP, Go. The docs use real examples, not stubs.

Frequent questions
What people ask before switching.
Do you take a cut of WhatsApp messaging fees?
No. Meta charges you directly per conversation at their published rate. SendyStack's plans price the platform — broadcasts, automations, the assistant, analytics — not the per-message cost.
What does it take to switch from another provider?
Most teams are live within an afternoon. CSV-import your contacts, point your Meta WABA at SendyStack via Embedded Signup, re-submit your templates (we draft them from your existing copy), and you're sending. We help at no extra cost for paid plans.
Will the AI ever train on my workspace data?
Never. The assistant runs per-conversation and is tenant-scoped — it can only ever read or act on the signed-in workspace's data, and Gemini API calls have training opted out by default at the platform level.
Where is data stored?
On Google Cloud Firestore + GCS, multi-region. PII is encrypted at rest with workspace-specific KMS keys. You can request export or hard-delete from Settings → Data at any time.
