Quick overview This workflow receives new signup events, enriches each contact with Twain (and optionally a LinkedIn lookup), drafts a personalized welcome email in Gmail, and posts review-ready previews to Slack, with optional LinkedIn-step handoff to HeyReach. How it works Receives a new signup via a POST webhook secured with header authentication (with optional disabled schedule-based backfills from Google BigQuery or Google Firestore). Normalizes the signup fields (email, name, UID, timestamps, LinkedIn URL) and de-duplicates signups by UID across workflow executions. If the signup has no LinkedIn URL but does have an email, looks up a LinkedIn profile URL via Findymail (or other disabled provider alternatives) and merges the resolved profile back into the contact. If the contact has a usable work email or LinkedIn URL, calls the Twain Generate Sequence API to research the person and generate a personalized welcome sequence, otherwise posts a “skipped” notice to Slack. Builds a formatted draft payload and previews (email steps vs LinkedIn steps) from the Twain response, including any warning flags and a link back to the lead in Twain.

See all Gmail→WURL and IP lookups through Greynoise and VirusTotal
This n8n workflow serves as a powerful cybersecurity and threat intelligence tool to look up URLs or IP addresses through industry standard threat intelligence vendors. It starts with either a form submission or a webhook trigger, allowing users to input data, URLs or IPs that require analysis. The workflow then splits into two paths depending on whether the input data is an IP or URL. If an IP was given, it sets the ip variable to the IP; however if a URL was given the workflow will perform a DNS lookup using Google Public DNS and sets the ip variable based on the results from Google. The workflow then checks the obtained IP addresses against GreyNoise services, with one branch utilizing GreyNoise RIOT IP Lookup to assess IP reputation and association with known benign services, and the other using GreyNoise IP Context to evaluate potential threats. The results from both GreyNoise services are merged to create a comprehensive analysis which includes the IP, classification (benign, malicious, or unknown), IP location, tags to identify activity or malware, category, and trust level. In parallel, a VirusTotal scan is initiated for the URL/IP to identify if it is malicious. A 5-second
