Quick overview
Quick overview This workflow collects a single email or a CSV upload via an n8n form, verifies each address with the Searchbug Email Verification API, appends the results to Google Sheets, and posts a valid/invalid count summary to a Slack channel. How it works Receives a submission from an n8n form that includes either a single email address or an uploaded CSV file. Routes the run to single-email processing or parses the uploaded CSV into one item per row. Normalizes each record to a consistent email field regardless of CSV header capitalization. Verifies each email by calling the Searchbug Email Verification API and continues even if some requests error. Extracts key fields (status, domain, MX, SMTP provider, and related flags) into a clean result object. Appends each verification result as a new row in a Google Sheets tab. Aggregates totals (valid/invalid/total) and posts a summary message to Slack. Setup Add your Searchbug credentials by filling in the CO_CODE and PASS query parameters in the HTTP request to Searchbug. Connect your Google Sheets account, set your target spreadsheet and the “Email Verification” sheet (or update the document and sheet names), and ensure the header columns match the fields being appended. Connect your Slack account and select the channel where the workflow posts the verification summary. If you submit CSV files, ensure the uploaded file is a .csv and includes an email column (any of email, Email, or EMAIL works). An n8n automation workflow template by Searchbug.
