SINGLE EMAIL VALIDATOR - REAL TIME (V2)
Below are the instructions for our single email validator API, which requires SSL. The API also requires that you have an active credit balance and will never consume a credit for any unknown result. This endpoint can be called asynchronously and is not currently rate-limited.
To test out our API without using credits, please use the emails provided in our Sandbox Mode (v2).
The response time for our API is between one second and 30 seconds. Since APIs are meant to be fast by nature, we limit the amount of time we spend validating an email address. If we encounter a slow mail server or a mail server with a greylisting algorithm, you will get an unknown result. You can always revalidate those conditions by uploading a file to the bulk email validator.
On average, 96-98% of all domains will return in 1 to 5 seconds. There are a handful of domains that run on Postfix/Dovecot, which have a 20-second connection time for real-time validations, and a very small fraction of other domains that are slow to respond to SMTP inquiries. All major ISPs will respond in 1 to 3 seconds, which is typically the majority of email distribution.
