Thanks for providing your domain "its0k.com" on Tempr.email.

The following steps are necessary:

1. Please confirm your e-mail address and the registration of your domain by clicking the following link:


2. Please change the e-mail server (MX-Record) of your domain "its0k.com" to: mx.discard.email

3. Optional: To forward your domain to the start page of Tempr.email, please change the IP address (A-Record) of your domain "its0k.com" to: 37.120.161.148
If you use your domain privately and anonymously just for you, then we do not recommend to forward your domain to the home page of Tempr.email, to avoid any conclusions to a disposable e-mail address.

Tempr.email checks automatically in the next 24 hours the change of the MX-Record.
If the MX-Record was changed successfully, the domain will be automatically enabled to receive e-mails.

Important: Please let us know if you are no longer reachable at this e-mail address. We need the contact to you in case of a change of the DNS-settings.
