At MINDO, we want you to fully understand how WhatsApp Business number quality works, a key indicator that directly influences your message deliverability, account stability, and your business’s overall reputation within Meta’s API. Maintaining good quality not only improves your communication results, but also ensures that your campaigns, notifications, and messages always reach your customers without restrictions.

​
What is WhatsApp number quality?

WhatsApp number quality is a metric that Meta uses to evaluate the experience users have when interacting with your business through WhatsApp Business. This parameter measures user satisfaction and compliance with Meta’s policies, reflecting whether people find your messages useful and relevant or, on the contrary, annoying or irrelevant. When your number maintains good quality, you can continue sending bulk, automated, or customer service messages without issues. But if it drops, Meta may limit your sending capacity or, in severe cases, temporarily block the number.

​
How number quality is measured

Meta assigns each number a quality category based on user behavior and the nature of the messages you send. This evaluation is automatic and dynamic, meaning it can change based on audience response. The quality levels are:

High

Your messages are well received, few users block or report your account.

Medium

Some users report or mute your messages; Meta detects slight signs of low engagement.

Low

There is a high rate of blocks or reports; your account may receive warnings or sending limitations.

​
Factors that can affect number quality

Several behaviors or practices can negatively influence your quality score. Some of the most common are:
  • Unsolicited messages: sending content to users who have not interacted or authorized the communication.
  • Rejected templates: using template messages with confusing, promotional, or non-Meta-approved text.
  • Excessive frequency: repeatedly contacting the same users in a short period.
  • Blocks and reports: if many users block your number or mark it as spam, quality will drop quickly.
  • Inadequate or repetitive content: generic or low-perceived-value messages tend to generate lower engagement.

​
How to improve or maintain good quality

At MINDO we help you apply best practices to protect your number’s reputation and maintain high quality.
1

Use relevant and clear messages

Communicate useful, personalized information with a clear purpose.
2

Obtain prior consent

Make sure the user has initiated the conversation or agreed to receive messages.
3

Segment your audiences

Send messages tailored to the type of customer or stage of the buying process.
4

Avoid bulk sending without context

Prioritize strategic communication, not quantity.

​
What happens if quality drops

When your number’s quality falls to the low level, Meta may apply the following measures:
  • Temporary reduction in sending volume.
  • Restrictions on using new templates.
  • Deactivation of automated campaigns.
  • Temporary or permanent suspension of the number (in cases of serious non-compliance).
MINDO will automatically notify you if your quality drops and will guide you step by step with recommendations to recover it, helping you maintain your account’s stability and your customers’ trust.

WhatsApp Business number quality is a direct reflection of how your customers perceive your messages. Keeping it high is essential to ensure the continuity and effectiveness of your campaigns.
