Most mistakes fall into four groups: permission, relevance, execution, and follow-up.
1–3. Ignore permission and expectations
Mistake one is treating any stored number as campaign permission. Two is using a vague opt-in that omits WhatsApp or message categories. Three is hiding the opt-out.
WhatsApp policy requires the number and opt-in permission and says businesses must honor discontinuation requests. Applicable law may add requirements.
- Record opt-in source and date.
- Name message categories.
- Apply opt-outs promptly.
- Prevent accidental re-import.
4–6. Confuse volume with relevance
Mistake four is sending to the full database for reach. Five is adding a name while ignoring context. Six is repeating campaigns without a frequency rule.
Build the smallest defensible group and explain why it receives the message. Exclude recent conversions and contacts already heavily messaged.
7–8. Neglect copy and files
Mistake seven is a dense promotional block with no context or single action. Eight is an untested, oversized, poorly named, or incorrectly typed file.
Preview missing variables, open every link, and download the actual attachment from a test message.
9. Launch without reply capacity
A conversational campaign may create questions within minutes. If no one is available, the advantage of the channel becomes frustration.
Decide who owns conversations, how assignment works, and which cases require escalation before launch.
10. Watch rates without learning
The final mistake is celebrating reads or regretting replies without linking data to the goal. Classify responses, examine failures, and record one test. Share that note with the people preparing the next campaign.
Do not change the audience, time, offer, and copy together. You will get a new result without knowing why.
