Email24-7 will also validate your e-mail address for you, and tell you which ones are invalid.
Our basic service costs $0.002 per lookup, it includes email validation and it returns the gender, age, and location of the owner, if available. When the data for an email address is not available to us, we don't charge for it, but we still validate it for you, and we try to infer the gender from the part of the address before the @ symbol.
As with our other services, Email24-7 can be accessed via API, file upload, or by manually typing-in addresses via the website.
We're putting the finishing touches on our more advanced Email24-7 packages and pricing, and we'll post this information in the coming days. In the meantime, please feel free to contact us with any questions.
