Open-source n8n templates for bulk email verification

说明与用途

n8n 模板用于批量验证电子邮件地址，将列表分为安全、审核和删除，处理提供商和域名的特殊情况，并提供实时注册验证的 webhook。

问题

Email lists often contain invalid or risky addresses that waste resources when used in sequences, CRMs, or agent workflows.

结果

The templates enable batch verification of email addresses, producing consistent verdicts and scores, and separating safe, review, and drop lists. They handle domain reordering, greylisting, and provider-specific quirks, and expose a webhook for real‑time signup validation.

工作流

• Read input data (Google Sheets rows or CSV upload).
• Send addresses in batches to an email‑verification API via HTTP Request node.
• Match results back to original records by address, not row order.
• Write status, score, and check keys back to the source (Sheets or CSV).
• Generate separate lists (send_safe, review, drop) for CSV workflow.
• Return allow/review/block verdict for signup webhook.
• Use AI agent tool to interpret results and decide actions.

证据

I built a set of four n8n templates around one job: checking whether email addresses are worth sending to, before they go into a sequence, a CRM, or an agent's hands.

来源

Results are matched back by address, not row order. The verifier groups addresses by domain, so they come back reordered; matching by position silently writes the wrong verdict on the wrong row.

来源

Everything uses the core HTTP Request node (no community node) and a Header Auth credential, so nothing secret lives in the JSON.

来源

The templates are MIT, but they call an email-verification Actor I built and run on Apify, which is pay-per-verified-address (there's a free tier).
