Safe sending checklist

No tool can guarantee that WhatsApp will never restrict an account. This checklist lowers the risk. Run through it before every campaign.

Before you send

• Everyone on the list agreed to hear from you, and you can show how and when.
• The list is clean: no duplicates, invalid numbers or people who asked to stop.
• Your message says who you are in the first line.
• Your message is personalised, not identical for everyone.
• It includes a simple way to stop, such as “Reply STOP”.
• The content is honest, and links go to sites you control.
• You tested the campaign on your own numbers.

While you send

• Start small with a new number, and increase slowly.
• Keep a steady pace. Do not send hundreds of messages in a minute.
• Do not message the same person many times in a day.
• Watch the replies. If many people say stop or complain, pause the campaign.

After you send

• Remove anyone who asked to stop, straight away.
• Note which messages got good replies.
• If your number is restricted, stop sending from it and review your list and content before you do anything else.

When to use the Official API

For business-critical or high-volume messaging, the Official WhatsApp Business API is the safer route. See WhatsApp API.
