About 33mail
33mail gives each user a subdomain such as you.33mail.com and forwards any alias at it to an existing inbox, with a block button in each forwarded message. Plans run from a free Lite tier to Premium at $1 a month, Pro at $5 a month and Enterprise at $50 a month. The terms say the service keeps the user's email address, IP address, aliases and email activity, and shares data only as needed to comply with law-enforcement requests. No operating company, jurisdiction or payment methods are stated on the pages read.
