CRM Enrichment & Hygiene with WhatsApp Profile API
Run a monthly or quarterly pass over every phone number in your CRM. Attach business flags, display names, profile pictures, and mark dead numbers. Keeps your list clean before WhatsApp Business campaigns or cold outreach.
Why run regular hygiene
- WhatsApp Business API partners charge per template-message attempt. Sending to dead numbers burns money and lowers sender reputation.
- Cold outreach campaigns that include dead numbers hurt deliverability across the whole list.
- CRM phone fields decay at 1-2% per month. After a year, up to 20% of your list may be inaccurate.
- Regulatory: in some jurisdictions, outbound messages to non-opt-in personal numbers carry penalty risk — detecting personal-vs-business reduces this.
Recommended cadence
| List profile | Cadence | Typical tier |
|---|---|---|
| < 10K contacts, mostly inbound | Quarterly | PRO ($35/mo) or PAYG |
| 10K-100K contacts, growth-stage SaaS | Monthly | ULTRA ($139/mo) |
| 100K+ contacts, agency or e-commerce | Monthly + ad-hoc | MEGA ($449/mo) or PAYG crypto |
| One-off migration / list purchase | One-time | PAYG crypto: $40 per 50K |
Workflow outline
- Export CRM phone column to CSV (or tap a webhook on contact update).
- POST to https://whatsapp-proxy.checkleaked.cc/bulk_check with body { "numbers": [...] } for synchronous batches, or POST /bulk/check/task/create for async tasks.
- For async tasks, poll GET /bulk/check/task/verify/{id} for progress and GET /bulk/check/task/results/{id} for results.
- Merge back: update is_wa_contact, is_business, wa_profile_pic_url, last_validated_at columns.
- Segment: "active WhatsApp business accounts" for B2B outreach, "active personal" for B2C flows, "not on WhatsApp" for SMS / email fallback.
