So this digest can only detect \"this WhatsApp number has an unanswered inbound message\", not which specific contact is waiting, per connection. If you need per-contact detail, capture `message.from` from the WASync Trigger's webhook payload into your own store as messages arrive, and join on that instead.\n\nSetup:\n1. Install the community node: n8n Settings -> Community Nodes -> npm package `n8n-nodes-wasync`.\n2. Create a free WASync account at https://developers.wasync.app/register, connect a WhatsApp number, then create an API key at https://developers.wasync.app/keys.\n3. In n8n, add a new \"WASync API\" credential using that key.\n4. Open the \"Settings\" node at the top of this workflow and fill in your own values. Never commit real portal URLs, tokens, or phone numbers.\n\nAlso add an SMTP credential in n8n (Credentials -> New -> Send Email (SMTP)) for the \"Send Digest Email\" node, and set your recipient address in the Settings node.\n\nDocs: https://docs.wasync.app/docs/guides/n8n?utm_source=n8n&utm_medium=template&utm_campaign=t5",
