Clean and dedupe your email list

Remove invalid, risky and dead addresses before your next campaign so you pay only to reach real people.

Email lists decay around 20–30% a year as people change jobs and abandon addresses. Mailing the dead ones costs money, drags down your open rates, and signals to inbox providers that your sends are low quality.

Run your list through the validator to flag undeliverable, disposable, and role addresses, then export the clean segment. Your metrics improve immediately because you’re no longer averaging in addresses that could never open.

For large or structured lists, pair it with Text-to-SQL to slice and query the results, or OCR if your contacts are trapped in scanned documents.

The tool for this
