A clean list means lower bounce rates, better deliverability, and a higher chance your emails land in the inbox — not the spam folder. It also protects your sender domain from being flagged by email providers.
Any business that relies on email to sell or communicate:
Our API lets you validate emails in real time — before they enter your database. It integrates with virtually any programming language and takes minutes to set up. Read the docs →
Best practice is to validate every new list you import and re-verify older lists every 30 to 90 days, as emails become invalid over time.
You can choose between pay-as-you-go credits (they never expire) or a monthly subscription. Plans start at $4 for 500 emails. The free tier gives you 50 verifications per day, forever.
Never. We process everything online in real time and don’t store any email addresses or query data. Your data stays yours.
