Email List Validator

Validate a list of email addresses in seconds. Paste your emails one per line or comma-separated, and the tool checks each one for proper format, missing domains, invalid characters, and other common issues. It also flags duplicates automatically so you can clean your list before sending a campaign. Results are shown with clear valid, invalid, and duplicate badges, and you can filter by status to focus on what needs fixing. Copy all valid emails with one click or export the full results as a CSV file with status and reason columns.
