How to Clean Email Lists From Pasted Text

Extract, deduplicate, lowercase, and format email addresses from pasted text before using them in a permitted workflow.

Best fit

Operators and marketers cleaning permitted internal lists, contact exports, signup snippets, or copied support notes.

Workflow summary

Email addresses copied from notes, messages, or exports often include names, punctuation, duplicates, and inconsistent casing.

This workflow extracts only the addresses and then formats the list for a destination field without validating deliverability.

Step-by-step workflow

  1. Paste the source text into extract-emails-from-text and keep duplicate removal enabled unless duplicates matter.
  2. Convert to lowercase if the downstream workflow expects normalized addresses.
  3. Use remove-duplicate-lines for a second pass when combining lists from multiple sources.
  4. Convert to a comma-separated list only when the destination field asks for that format.

Quality checks

  • The source list is permitted and does not violate consent, privacy, or anti-spam rules.
  • Important plus-addressing, subdomains, and unusual but valid addresses are reviewed before deletion.
  • The final output is not treated as verified deliverability data.

Privacy and limits

Current TidyUtilities tools process pasted text in the browser. Do not paste regulated, confidential, customer, or third-party data unless your own rules allow browser-based tools for that workflow.

This page is a workflow guide, not a guarantee that the cleaned output is legally compliant, deliverable, import-safe, or ready to publish without review.

Frequently asked questions

Does this verify email addresses?

No. It extracts and formats visible email addresses. It does not check mailbox existence, consent, or deliverability.

Can I use this for scraped email lists?

This workflow is intended for permitted data cleanup. Do not use it in ways that violate privacy, consent, or anti-spam requirements.
