/v0/check_email

/v0/check_email

Sunset notice: please use /v1/check_email instead. Both endpoints accept the same input arguments and return the same output; only their internal implementation differs. Perform a comprehensive verification of an email address. Unlike the /v1/check_email endpoint, this endpoint performs an email verification immediately, without considering the Reacher server's throttling, concurrency, and other configurations. As such, this endpoint is slightly riskier than /v1/check_email, as the Reacher server's IP reputation can be impacted if this endpoint is called too frequently.
