What to Do About Blockages and How to Reduce Their Risk

WhatsApp blocking algorithms operates in a way that we cannot pinpoint a single cause for blocking. It resembles a system of penalty points: the more penalty points an account accumulates, the higher the risk of being blocked, and conversely, the fewer penalty points, the lower the risk.

Certainly, although we don't have definitive knowledge of the criteria for earning these points, hypothetically, it might work like this:

If you're added to someone's contacts list, you gain 1 point. If marked as spam, you lose 1 point, and so on. Different accounts may start with different numbers of "points," with the primary metric being the WhatsApp account's lifespan and the level of activity in communicating with clients.
New SIM card
WhatsApp can potentially block a new SIM card even before you send the first message through the bot, at the moment of authorization. To prevent this, you need to allow WhatsApp to "live" on this card for a few weeks, for example, engage with clients manually and connect after this period.
Mass mailings
Avoid mass mailings as they inevitably trigger blocks for several reasons:
  1. They contain the similar text, which increases the risk of blocking
  2. They are sent to a large number of people — 5 "this is spam" reports in a row almost guarantee a block
  3. They contain links

As a solution we suggest switching to SMS for mass mailings, perform the mass mailing, and then switch back to WhatsApp, or use cascading messaging.
Templates
A crucial factor influencing blocking is templates, as they are the easiest to modify. We have developed five main recommendations regarding them. You can also use Chategy default templates that are already provided inside your account.
If you're using your own templates:

  1. Always introduce yourself, especially in appointment notifications when the first message essentially received by the client
  2. Use links only when absolutely necessary, when, for example, requesting feedback; in all other cases, especially in the first message, this creates a risk of blocking
  3. Incorporate emojis to make the communication look more "human"
  4. Utilize as many CRM variables as possible, such as the recipient's name or the name of the service, to make messages more diverse
  5. Strive to engage the customer; the more they respond to messages, the better
Other reasons for blocking include:

  1. WhatsApp doesn't appreciate messages sent using country codes other than your own. Try to minimize sending messages to other countries. In the settings of our bot, there's an option to disable sending messages to international numbers
  2. Avoid sending an excessively large number of messages. The ideal scenario is up to 30 messages per hour, approximately 700 per day. If you exceed this limit, it's better to disable certain types of notifications
