How do I set up a WhatsApp welcome message for new customers?

You can send an automatic first reply to customers who message your WhatsApp number for the first time. Each customer receives it only once.

Open Settings > Configure Platforms > WhatsApp.
On the Welcome message card, click Enable.
Pick a language at the top of the editor (click + to add one). Each language keeps its own text.
To send one language to everyone, keep that language selected when you click Save.
To let Pushwoosh pick per customer, write each language, then select Default language before saving. Pushwoosh matches the customer's Language tag exactly, then by base language (en-US matches en), then falls back to Default language. Give Default language its own text, or unmatched customers get no greeting.
To personalize, click Personalization, choose a Tag or User ID, a format modifier, an optional Default tag value, and click Insert.
Optionally, add an image in Attachment URL (shared across all languages).
Click Save.

Use the same card to Disable, Edit message, Delete, or View detailed statistics.

Things to know:

If your sender is blocked by Meta, the welcome message isn't delivered until sending is restored.
If a journey is also triggered by incoming WhatsApp messages, a customer may get two messages back to back. Adjust the journey trigger or disable the welcome message.
