Telegram bot: extract & store TikTok and LinkedIn data to Google Sheets with Dumpling AI

Pull contacts, verify each address with BillionVerify, and continue to Dumpling AI — only deliverable addresses get through.

Why verify before the send

Sending to invalid, risky, catch-all, or disposable addresses spikes your bounce rate and erodes sender reputation. A verification gate before the Dumpling AI step removes that risk automatically — only deliverable addresses continue, the rest are flagged.

The workflow

BillionVerify — verification sits right before the send.

Instead, inform the user: \"I could not retrieve data for that profile. Please check the link/username.\"\n- Do not make up data. Only save what the scraper returns.\n\nBegin by identifying which platform the user wants to scrape."

FAQ

Why verify before sending in Dumpling AI?

Verifying first keeps your bounce rate low, which protects your sender reputation and your results.

How do I import this workflow?

Download the JSON, then in n8n go to Workflows → Import from File (or paste it). Install the BillionVerify community node and add your API key credential.

What happens to risky or catch-all addresses?

They are routed to the false branch and excluded from the send. You decide whether to retry, review, or drop them.

Add verification to your workflow

Create a free account, grab your API key, and stop bounces before they happen.
