Explanation:
When the quality rating reaches low quality, your phone number quality rating changes to Low. If the phone number quality is Low and on track to be downgraded to a lower message tier, the phone number status changes to Flagged. When a phone number is Flagged, if the quality doesn’t improve over seven days, the status returns to Connected. However, the messaging limit will decrease to the next level. For example, the phone number that used to have the 100,000 messaging limit now has the 10,000 messaging limit.
- Connected: You can send outgoing messages within your set messaging limit.
- Flagged: This status occurs when the phone number’s quality rating changes to Low and is on track to be downgraded to a lower message tier. Businesses can’t upgrade messaging limit tiers while the status is Flagged. If the quality rating:
- - Improves to a high or medium quality by the seventh day, the status will return to Connected and your messaging limit tier will remain unaffected.
- - Does not improve by the seventh day, your status will return to Connected, but your messaging limit will decrease to the next level.
The blocking of your number will depend on the quality rating of phone number.
Your quality rating is a rating based on the recent messages that your customers have received over the past seven days. This rating is determined by the feedback from your customers, such as the reason to block your phone number and other reporting issues.
You can find the quality rating in the WhatsTool Business setting with the Phone numbers. The Quality rating column displays the quality states, including:
- Green: High quality
- Yellow: Medium quality
- Red: Low quality
You can become eligible for more features when your business maintains a High quality rating. When the user blocks your business, they can select a block reason, including No longer needed, Didn’t sign up, Spam, Offensive messages or No reason.
