Why opt-in and quality are linked
WhatsApp is a personal space. People expect messages from friends and family, so messages from businesses are held to a higher standard. The platform requires that you have permission before you send, and it watches how recipients respond. Customers who block or report you lower your quality rating, and a low rating can reduce how many people you may message and, in serious cases, restrict your number.
The practical lesson is that opt-in and quality are two sides of one habit: send people what they asked for, when they expect it.
Collecting opt-in
- Ask clearly. Say it is for WhatsApp, what you will send and roughly how often
- Use an action. A ticked box, a button or a message the customer sends first
- Offer value. Explain the benefit: order updates, support, offers
- Confirm it. Send a welcome template that repeats the promise and how to stop
- Record it. Store the date, source and exact wording, as in the consent guide
Good places to collect opt-in
- Checkout or sign-up forms with a separate WhatsApp option
- A click-to-chat button or QR code on your website, packaging or store
- An inbound message from the customer asking for help
- A customer-service call where the agent records consent
- A paper or in-store form with a clear statement
What quality means
Quality is a measure of how recipients react to your messages over recent days. Blocks and reports count against you; reads and replies are signs of relevance. The exact scoring is set by WhatsApp and can change, so read the current documentation.
Protect your rating
- Message only people who opted in and expect the message
- Limit frequency and apply a weekly cap per person
- Segment marketing by interest so messages are relevant
- Send at times that suit the recipient
- Make stopping easy and honour it at once
- Watch block and report feedback after each campaign
- Pause a template that receives poor feedback
Warning signs
| Sign | Likely cause | Response |
|---|---|---|
| Falling read rate | Content not relevant | Segment better, change the message |
| More blocks after a campaign | Too frequent or unexpected | Reduce volume, review opt-in source |
| Template paused or limited | Poor quality feedback | Rewrite or retire the template |
| Quality rating drops | Sustained negative feedback | Stop marketing sends and let it recover |
Recovering
If your rating falls, the remedy is restraint. Pause marketing, review who you sent to and why, remove people who did not clearly opt in and resume slowly with highly relevant, high-value messages. Recovery takes time, so avoid sending large campaigns until the rating is stable.
Business profile and trust
Customers decide whether to trust a message in a second. A verified-looking profile with a clear name, logo, description and contact details increases reads and reduces reports. Keep your display name consistent with the brand people know and make sure the number you use is one you will keep.
A quality dashboard you can build in an hour
You do not need special tools. Export your campaign data weekly and chart four lines: messages sent, delivered, read and replied, plus the number of blocks and reports if you receive them. Add the quality rating and the date of each campaign. After a month you will see which campaigns lifted engagement and which lowered it. Share the chart with the marketing team and agree a simple rule, for example that any campaign with a block rate above a threshold you set must be reviewed before the next send.
Frequently confused points
- Opt-in is not a one-time forever grant. Refresh it when a customer has been inactive for a long period.
- Reply is not consent. A customer who writes to ask about an order has opened a service conversation, not agreed to marketing.
- Service and marketing differ. Keep their templates, consent and reporting separate.
- Numbers matter. Use a number dedicated to the purpose, so one team's mistakes do not affect another.
Designing a welcome flow
The first message after opt-in sets the tone. Send a short utility or marketing template, matching what the customer agreed to, that thanks them, repeats what they will receive and gives a quick reply to stop. Then give immediate value, such as an order status link, a catalogue or a help menu. Customers who get something useful in the first minute are far less likely to block you later.
Handling reply keywords
Decide the words your system understands and tell customers about them. A typical set is STOP to unsubscribe, HELP for support and START to resubscribe. Normalise case and punctuation, and accept local-language equivalents. Log every keyword event with the time, because those records are part of your consent proof. Test the keywords each month on a real handset, since a broken opt-out is the fastest route to complaints.
Governance for larger teams
When several teams send from one account, quality problems become shared problems. Assign a single owner for the WhatsApp programme, publish a short sending policy that covers consent, frequency and approval, and require that new templates and campaigns are reviewed against it. Review quality and block rates in a weekly meeting for the first quarter, then monthly once stable.
Practical checklist for launch week
Before your first campaign, confirm the business profile is complete, templates are approved in the right category, opt-in records exist for every recipient and the stop keyword works. Start with a small, highly engaged audience, watch reads, replies and blocks for two days and scale only if the numbers look healthy. This slow start costs little and protects the rating you will rely on for every later campaign.
Review and ownership
Assign a named owner to this area and put a review on the calendar every quarter. At each review, check the metrics described above, read the last quarter's incidents and update the runbook with anything you learned. Short, regular reviews keep small drifts from turning into outages, and they make onboarding new team members far easier because the current practice is written down in one place.

Frequently asked questions
How do I know my quality rating?
It is shown in your WhatsApp Business account and in the Telnxo dashboard when connected.
Can I buy a contact list?
No. People on a purchased list have not opted in to hear from you, and messaging them harms your quality and breaks policy.
Is a customer's phone number enough to message them?
No. You need their permission to message them on WhatsApp.
What if a customer opts out?
Stop sending marketing messages at once and record the opt-out.
