Message Templates need to be approved by WhatsApp before they can be used for sending a WhatsApp bulk message. Some BSPs like 360dialog allow you to create and submit Message Templates directly from respond.io. Conversely, Twilio users must create Message Templates in the Twilio console and add them to respond.io manually.

On respond.io, you can view the status of your Message Templates. There are three statuses - Submitted, Approved and Rejected. If a Message Template is rejected, you’d be able to find the reason for its rejection in the platform. You can edit and resubmit rejected Message Templates for approval.

Apart from this status, WhatsApp API provides another quality insight called quality rating. Being blocked by customers will result in a drop in the Message Template’s quality rating. Check out these best practices for maintaining a High quality rating.

Once an approved Message Template reaches a Low-quality rating, it will be assigned a Flagged status. The status will switch to Disabled if the quality rating does not improve in seven days. You can’t send or edit Message Templates that have a Disabled status.

One thing to note: if you send WhatsApp bulk messages to a large number of recipients, they won’t be delivered all at once. The Contacts' country codes and numbers determine the order in which WhatsApp bulk messages are sent. Country codes with lower numbers will be put at the front of the queue.

WhatsApp API has several measures in place to prevent businesses from misusing its bulk messaging feature. Let’s take an in-depth look at them in the following section.

What You Need to Know Before You Send a Bulk WhatsApp Message

To protect its users from spam and encourage high-quality bulk messages, WhatsApp has introduced phone number tiers, phone number status and phone number quality ratings.

Phone Number Tiers

The number of recipients you can send bulk messages with WhatsApp API depends on your phone number tier. The higher your phone number tier, the more unique Contacts you can message in a rolling 24-hour period.

To send bulk WhatsApp messages to a large audience, you need to upgrade the phone number tier of your WhatsApp account. In order to do so, send twice the number of messages allowed in your current phone number tier within seven days.

Phone Number Status and Quality Rating

Phone number status and quality rating can affect your ability to send a bulk message on WhatsApp. To send WhatsApp bulk messages without restriction, a phone number’s status must be Connected.

When your phone number is reported or blocked, its rating will drop to Low. Subsequently, its status will turn to Flagged. While in the Flagged status, you can’t upgrade your number’s messaging tier. If the quality rating doesn’t improve in seven days, the status will return to Connected but a lower messaging limit will be imposed.

Your number will be assigned a Restricted status if it reaches its messaging limit while having a poor quality rating. A Restricted phone number can only respond to inbound conversations - it won’t be able to send WhatsApp bulk messages to new unique Contacts. Find out more about bulk whats app sender in the blog.
