disclaimer: I'm not a shill for Fastmail, just a happy (family plan) user after Gmail did me the favor of changing pricing and having me look around for alternatives.

$10/month is surprisingly high for temp-mail.org's service. Fastmail is $3-5/month paying monthly, and that includes full regular email service plus (at the $5/month level) your own domains, and on top of that they offer the disposable email address service. It seems like temp-mail's only extra feature is accepting cryptocurrency.
