WhatsApp: Grey or White — Which to Choose and When to Switch?

When integrating WhatsApp with a CRM, clients always have one question: which WhatsApp should we connect? I address this in every project — here's the framework I use.
Terminology

Grey / unofficial / Personal WhatsApp — all the same thing: connecting via QR code or phone number, bypassing the official API
White / official / WhatsApp Business API / WABA — all the same thing: Meta's official solution through authorised partners

Pros and Cons

Grey WA
+ Quick setup, no verification required
+ No restrictions on incoming messages, works from a personal number
+ Can message first without a template
— Instability: authorisation drops, phone must always be online
— Risk of being banned without warning during mass campaigns
— Meta doesn't announce updates — temporary outages affect all "grey" integrators

WABA
+ Official API — stable, no phone required
+ Mass campaigns via Meta-approved templates
+ Verified badge, increased brand trust
+ Tiers: from 250 to 100,000+ conversations per day
— Paid templates (from 01.07.2025 — charge per template message sent)
— Meta Business verification required — takes 1 week to 1 month
— Cannot message first without a template

Risks and Opportunities

Grey WA
— Risk: losing all conversation history if the number gets banned
+ Opportunity: fast launch with no upfront budget

WABA
— Risk: template blocked for violating Meta policies
+ Opportunity: funnel automation, chatbots, mass notifications without ban risk when rules are followed

When to Use Which

Grey WA is suitable if: team is up to 5 managers, no mass campaigns, limited budget, quick start needed, CRM is just being tested
WABA is suitable if: team is 5+ people, campaigns/notifications are needed, stability is important, business is scaling

When to Switch from Grey to White
— Number starts getting banned or receiving warnings from WhatsApp
— Mass campaigns are needed regularly (more than 100 contacts per day)
— Incoming leads (more than 100 per day) need templated messages sent to them
— Loss of conversation history when a manager leaves has become a problem
— Business has grown, a verified brand presence in the messenger is needed

How to Choose

Before connecting anything, I always clarify:
1. How many managers will be working in WhatsApp?
2. Do all managers use one shared number or each their own?
3. How many WhatsApp numbers do you plan to connect?
4. How many new leads do you receive per day?
5. How many enquiries from new and existing clients per day?
6. Are you planning outbound campaigns?
7. If yes, how often and to what size of audience?
8. Do you already have a number that has been used to communicate with clients?
9. Have you experienced any bans or warnings from WhatsApp?
10. Is brand verification (Meta badge) important to you?
11. What budget have you allocated for the messenger channel?
12. Is automation needed: chatbots, trigger messages?

Answers to these questions will help determine whether grey, white, or both channels simultaneously are the best fit for your situation.
