Benefits of WhatsApp Bulk Message

WhatsApp bulk messages provide numerous advantages that make them an attractive option for businesses to effectively interact with their target audience.

WhatsApp offers two bulk messaging solutions to cater to different business sizes and messaging needs — WhatsApp Business App and the WhatsApp Business Platform (also known as WhatsApp API). Let’s first talk about WhatsApp bulk messages on the WhatsApp Business App.

How to Send Bulk Messages on WhatsApp: WhatsApp Business App

In general, the WhatsApp Business App works for micro and small businesses. It’s free, easy to use and doesn’t rely on external software to send broadcasts.

Keep in mind that the WhatsApp Business App is not a viable option for medium or large enterprises, as the app has a limitation of 256 contacts per bulk message or per broadcast list. If you are an SME or enterprise looking to send WhatsApp bulk messages, the best choice is WhatsApp API.

4. MessageBird

MessageBird is a WhatsApp bulk messaging solution initially developed for SMS. Despite supporting many popular channels, it only supports bulk messaging on WhatsApp and SMS.

Additionally, setting up WhatsApp bulk messages on MessageBird requires technical knowledge since it is not a native feature. The platform also experiences downtime 2 to 3 times a month, which can be disruptive to your business operations.

WhatsApp also has measures put in place to ensure that only high-quality bulk messages are sent. Therefore, businesses must follow WhatsApp's regulations to send bulk messages with WhatsApp API. When sending broadcasts, WhatsApp API users should be familiar with the following:

  • WhatsApp Broadcast API messaging limits
  • WhatsApp message template categories
  • Phone number status and quality rating

Phone Number Status and Quality Rating

When your phone number is reported or blocked, its rating drops to Low. Subsequently, its status turns to Flagged. While in the Flagged status, you can’t upgrade your number’s messaging limit. If the quality rating doesn’t improve in seven days, the status returns to Connected, but your messaging limit decreases by one level.

WhatsApp Bulk Message Tips to Avoid Getting Marked as Spam

To avoid being marked as spam when sending bulk messages on WhatsApp, there are several strategies you can implement.

Familiarize yourself with WhatsApp Policies

Take the time to understand the WhatsApp Business Business Messaging Policy before sending bulk messages. By complying with these rules, you can maintain a positive reputation and avoid being flagged as spam.

Obtain Explicit Consent

Before adding recipients to your broadcast list, always ensure you have obtained their explicit opt-in consent. Clearly communicate the type of messages they will receive and provide an easy opt-out option. This helps to establish a foundation of trust and respect for their privacy.

Respect Opt-out Requests

Provide recipients with a simple way to opt out of receiving further messages. Ensure that their opt-out requests are promptly acknowledged and honored by removing them from your broadcast list without delay.

Monitor Feedback

Pay close attention to user feedback and responses. If recipients report your messages as spam, take immediate action to address their concerns. Actively engaging with your audience and promptly resolving any issues can help prevent further reports.

To gather feedback from customers and refine your messaging content and approach, consider utilizing surveys. Ask specific questions about their preferences, needs and opinions regarding your messaging content and approach. This method allows you to collect structured data and quantifiable insights.

Remember, gathering and acting upon customer feedback is an ongoing process. Continuously refine your bulk message content and approach based on the feedback received to ensure that your communication is always aligned with your audience's expectations and needs.

Be Transparent

Maintain transparency by clearly communicating the purpose and value of your messages. By being open and honest, you build trust and establish a strong relationship with your recipients, which ultimately enhances privacy protection.

Send Relevant and Valuable Content

It is crucial to send messages that are relevant and valuable to your recipients through WhatsApp bulk messages. Avoid bombarding them with frequent, generic, or irrelevant messages, as this can lead to being perceived as spam. Tailor your content to the specific needs and interests of your audience to increase engagement.

Avoid spammy content

Craft messages that are valuable, relevant, and not overly promotional. Avoid using excessive emojis, capitalization or misleading information. It's crucial to maintain a professional and trustworthy approach.

Timing matters

Consider sending messages at appropriate times to improve engagement rates. Avoid late hours or times when people are less likely to be active on their phones. By being mindful of the timing, you can increase the chances of your messages being marked as spam.

Optimize Message Length

Keep your messages concise and to the point. Long and wordy messages can be perceived as spam and might discourage recipients from engaging with your content. Make sure your message effectively communicates its purpose in a clear and concise manner.

Limit Frequency

Avoid excessive messaging that might overwhelm recipients. Respect a reasonable frequency for sending bulk messages, ensuring that recipients are not bombarded with an excessive amount of communication.

By implementing these strategies, you can significantly reduce the risk of being marked as spam when sending bulk WhatsApp messages.
