Email List Cleaner

This email list cleaner validates every email address in your list against four criteria: syntax validity (correct format), disposable provider detection (25+ known throwaway email services), role-based address identification (admin, info, noreply, support, etc.), and duplicate detection. Results are categorised and colour-coded so you can review and filter before exporting.

Clean email lists are critical for deliverability. Sending to invalid addresses causes hard bounces, which damage your sender reputation with ISPs. Sending to disposable addresses wastes sending quota. Role addresses often have lower engagement and may have spam filters. Duplicates inflate your list size and can annoy recipients who receive the same email twice.

All processing happens entirely in your browser — your email list never leaves your device. This is important for GDPR and data privacy compliance when handling customer email addresses.
