How to avoid blocking my WhatsApp number?
Tips and Hints
- Set up the advertising in such a way that the user is the first to write to you (the “Mark as Spam” button does not appear).
- Send messages only to your loyal database of numbers or your clients only.
- Don’t send the same messages, change them: personalize the messages (“Hi, %Customer_name%”).
- Take advantage of the opportunity to subscribe and unsubscribe from your mailing list in each message. To do this, add reply buttons (e.g., “Write 0 to unsubscribe”)
- Offer users to save your contact.
- Minimize the presence of a link in messages at first use of the bot.
- New phone numbers have a greater risk of being blocked. Before connecting to a completely new number, you can use WhatsApp personally for some time (chat with other numbers so that you have a variety of incoming and outgoing messages from different numbers).
- When you start using the bot, send no more than 6 -12 messages per minute, i.e. send messages in batches, not all at once. The longer your bot works, the more messages you can send.
