🧹 What This Recipe Does
The Clean Contact List recipe chains four operations in one click: it extracts every email address from the text you paste, removes duplicates, lowercases every address, and strips common role-based emails (noreply, info, admin, support, etc.). You end up with a deduped list of real people ready to import into your CRM, email service, or spreadsheet.
Before this recipe, this workflow meant opening four separate tools, copy-pasting between them, and keeping track of intermediate state. Now it's one paste and one click. Everything runs in your browser — no uploads, no sign-up, no limits.
⚡ How to Use
- Paste your text — from signatures, CSV exports, spreadsheet columns, or any source
- Tweak the cleanup options (optional) — toggle dedupe, lowercase, and role-email stripping
- Add a domain filter (optional) — keep only a specific domain or exclude one
- Pick your export format — Plain text, CSV, Mailchimp CSV, Gmail BCC, or SQL IN clause
- Copy or download — your clean list is ready to use

❓ Frequently Asked Questions
What does this recipe do?
It chains together four operations in one click: extract all email addresses from your pasted text, remove duplicate emails (case-insensitive), lowercase every email, and optionally strip common role-based emails like noreply@, info@, admin@, support@, and others.
What are role emails and why strip them?
Role emails are generic addresses like noreply@, info@, admin@, support@, sales@, hello@, contact@. They are not tied to an individual person, so sending marketing or outreach to them usually has low response rates and can hurt your sender reputation. Stripping them gives you a cleaner list of real people.
Is my data private?
Yes. Everything runs in your browser — no text or emails are ever sent to any server. Your pasted data never leaves your device.
What export formats are supported?
Plain text (one per line), CSV (with an "email" header), Mailchimp CSV (with "Email Address" header), Gmail BCC (comma-space separated), and SQL IN clause (single-quoted, comma separated).
What file formats can I paste from?
Any text source: email signatures, CSV exports, spreadsheet columns, web pages, PDF text, Word documents, chat logs. If you can copy it as text, you can paste it.
Can I use this for a huge list?
Yes. The tool handles thousands of emails instantly since it all runs in your browser. No upload limit, no row limit, no waiting.
