Check email

API endpoint to validate the user's email address and bring it to the correct and valid format (if possible and necessary). The endpoint does NOT create a new user in the system.

In response, the request returns information about the user's email address:

Response params	Description
reason	Reason why the email is invalid (only if valid = false);
orig	Original user email;
valid	Email validity: true / false;
email	User email that will be stored;
vendor	Mailer: AOL, Google, Mail.ru, Hotmail, Yahoo!, Rambler, Apple, Ukr.net, etc.;
domain	Mailer domain;
trusted	true / false (this parameter determines whether the vendor of the email address is verified: for example, trusted = true for well-known mailers such as Google, Mail.ru, Outlook, etc. If we do not have information about the vendor of the email address, then the value trusted = false).

Reasons why the email may be invalid:

Reason value	Description
invalid	Incorrect email format;
mx_record	There is no MX record for the mail domain;
application	Email refers to the application (for example, fb.com);
