Email Validation Dashboard

Protect Your Reputation

High bounce rates signal to ISPs that you're a spammer. Our validation keeps your bounce rate below 1%, protecting your sender reputation and ensuring high deliverability.

Reduce Marketing Waste

Stop paying for invalid leads. By cleaning your list, you ensure your marketing budget is spent on reaching real people who can actually convert into customers.

Advanced Data Security

We take your data privacy seriously. All files are processed over secure SSL connections and deleted automatically after 30 days to ensure full GDPR compliance.

How It Works

Our multi-layered validation process ensures the highest accuracy in the industry.

Syntax Check

We verify the email address against RFC standards, ensuring it contains all required elements like the '@' symbol and valid domain extensions.

MX Record Check

Our system queries DNS records to confirm that the domain has valid mail exchange servers configured and ready to receive mail.

SMTP Ping

We establish a low-level connection with the mail server to verify the existence of the mailbox without ever sending an actual email.

Catch-all Detection

We identify "catch-all" domains that accept any email sent to them, which helps in calculating the true deliverability risk of your list.

Real-time Protection

Integrate our API into your signup forms to stop invalid emails at the source. Prevent bounce-backs, reduce fraud, and maintain a pristine sender reputation from day one.
