What are the limitations of using the WhatsApp Business API for sending bulk messages, and how can these limitations be overcome while adhering to WhatsApp's policies?

The WhatsApp Business API has limitations on sending bulk messages to prevent spam and ensure a positive user experience. 'Bulk messaging' refers to sending the same message to a large number of users at once. First, there are quality rating limitations. WhatsApp assigns a quality rating to each business based on user feedback. Sending low-quality or unwanted messages can negatively impact your quality rating, potentially leading to reduced sending limits or account suspension. Next, the message template approval process must be followed. Only pre-approved message templates can be used for sending bulk notifications. This ensures that the content is relevant, non-spammy, and compliant with WhatsApp's policies. Also, explicit opt-in is important, requiring explicit opt-in from users before sending them any promotional or marketing messages. Sending unsolicited messages is strictly prohibited. Fourth, there are sending limits, with WhatsApp imposing daily sending limits based on the business's quality rating and the number of users they are messaging. These limits can restrict the number of messages you can send in a given day. To overcome these limitations, businesses can implement segmentation and personalization. Segment your audience based on their interests, behavior, and demographics, and send personalized messages that are relevant to their individual needs. Also, focus on quality content. Ensure that your messages are valuable, informative, and engaging to your audience. Avoid sending generic or repetitive messages. Regularly monitor your quality rating. Monitor your quality rating and take steps to improve it if it is declining. Respond to user feedback and address any issues that may be impacting your rating. For example, send relevant content to users based on their interests.
