WhatsApp Outreach System — Business API + Personalization
A WhatsApp outreach system sends personalized messages to opt-in contacts through the official WhatsApp Business API, manages approved templates, runs multi-step sequences and handles replies in real time. We build it as a custom solution on your number and your Meta WABA account — no per-contact monthly fee, full control over lists and compliance. Expect 70-85% open rates versus 18-25% for email, with no ban risk because every initial message goes through an approved template.
What the solution includes
The WhatsApp outreach system is fully custom — our own backend on top of Meta's official Cloud API, your WhatsApp Business account and your data. You are not locked into a platform that charges per message sent or freezes your account without notice.
- ✓Opt-in list management — consent captured via forms, QR code, checkout or import, with date, source and consent text stored per contact — the foundation of legal outreach.
- ✓Template manager — create, version and submit message templates to Meta straight from the admin panel, with variables, buttons and media, no agency wait.
- ✓Contact-level personalization — name, company, last order, deal stage or any CRM field is merged into the template so every message reads 1-to-1, not like a mass broadcast.
- ✓Multi-step sequences — automated flows with conditions — send a follow-up only if no reply within 48h, stop on reply, branch on behavior.
- ✓Reply handling (inbox) — a shared team inbox with conversation routing, quick replies, tags and 24-hour session window management per Meta rules.
- ✓Compliance guard — automatic opt-out on "STOP", rate limiting by quality tier, and blocked sends to any contact without recorded consent — protection against bans and GDPR fines.
- ✓Analytics and attribution — delivered, read, replied, conversion at campaign and template level, plus UTM-tracked links that feed data back into your CRM.
- ✓CRM sync — every reply, opt-out and conversion is written to the contact card so reps see the full thread without leaving the CRM.
Who it is for
Stores that want abandoned-cart reminders, order confirmations and seasonal promos to customers who explicitly opted in at checkout. One branded template with a product image and button hits 90% delivery and recovers 12-20% of abandoned carts in the first 24 hours.
Reps with long cycles using WhatsApp for warm follow-up after a meeting or demo. Sequences send an offer reminder, materials and a re-engagement nudge, stop on reply and push the hot contact back into the pipeline. Reply rate runs 3-5x cold email.
Clinics, gyms, insurance brokers and SaaS firms sending appointment reminders, policy or subscription renewals and review requests. Name and service personalization plus automatic opt-out keep Meta marketing limits clean and the quality rating high.
How we build it
We are not a reseller of a broadcast platform. The solution runs on your Meta WABA account and our backend — lists, consents and conversation history stay with you, not a third party that can raise the per-message price or close the profile.
1. WABA setup and verification
We register or migrate your number into the WhatsApp Business Platform, connect Meta Business Manager, pass business verification and request the display name. We configure Cloud API webhooks and quality-tier monitoring so you ship with a high daily limit from day one and no risk of conversations stopping over an unverified profile.
2. Opt-in architecture and lists
We design how consent is collected — site form, checkout checkbox, QR code or import from a base with proven opt-in. We store source, date, consent text and channel per contact, then segment lists by behavior and CRM fields because precise targeting, not volume, keeps the quality rating green.
3. Templates and sequences
We write and submit message templates per category (marketing, utility, authentication) with variables and CTA buttons, then build the sequence logic — timers, reply conditions, branches and stop rules. You test the full funnel on a sample segment before going live.
4. Inbox, routing and compliance
We ship a shared team inbox with routing rules, quick replies and tags that respects Meta's 24-hour session window. The compliance layer catches "STOP", blocks sends without consent, rate-limits to the current quality tier and logs everything for audit — protection against both a Meta ban and GDPR penalties.
5. Launch, monitoring and iteration
We launch the first campaign on a limited segment, watch delivered, read, reply and quality rating in real time, then optimize templates and timing on the data. Volume scales gradually so the number's daily limit grows healthily. Each month we rewrite the worst-performing templates from real replies.

Frequently Asked Questions
Is it legal to send outreach messages over WhatsApp?
Yes, provided the recipient gave explicit opt-in consent to receive messages from your brand on WhatsApp and you use approved message templates for the first contact. The system blocks sends without recorded consent and handles "STOP" automatically. This protects you from both Meta bans and GDPR penalties — which is why opt-in architecture is the first thing we build.
How is it better than mass-sending from personal WhatsApp?
Sending from personal or the WhatsApp Business app to cold contacts gets the number banned within days. The official Business API with approved templates and quality-tier monitoring is the only scalable, legal path. You get a high daily limit, delivery reports, automation and a shared inbox — things the personal app does not and never will allow.
How much does a WhatsApp outreach system cost?
From €2,400 for a full system — WABA setup and verification, opt-in forms, template manager, up to 3 sequences, team inbox and basic CRM sync. An extended version with advanced segmentation, template A/B tests and multi-number rotation starts from €3,900. The only recurring cost is Meta's real conversation fees and hosting — no per-message markup from us.
How long does launch take?
Technical development and integration take 3-5 weeks. Business verification and template approval from Meta are outside our control and usually add 2-7 business days. We start verification and templates in parallel with development so you are ready for the first campaign as soon as Meta approves the profile.
Does it connect to our CRM and site?
Yes. We build API integrations to your CRM system, online store or internal software so lists fill automatically, replies land on the contact card and conversions attribute to the right campaign. See also CRM WhatsApp Viber integration for two-way conversation sync.
