The Timeout Parameter

The timeout parameter informs the API for how much time it needs to verify an email before giving up and coming back with an unknown result code. The total request time can exceed this timeout, as network latency is not taken into consideration. This can be helpful when verifying emails at the point of entry to prevent long wait times for your users.

Usage Guidelines

Handling Aliases

When verifying emails that contain aliases that use a + character extra consideration needs to be taken when encoding these for x-www-form-urlencoded content-types. Make sure this character is being encoded as %2B, as the + character is treated as a non-breaking space when the string is decoded.
