Our opinion

The only provider to provide full anonymity with true 0 log and immediate deletion of emails is CTemplar. It is not in a country part of the LAT treaty, and accept payment is bitcoin. It is the only one that match all criteria. However CTemplar suffered a catastrophic incident on July 8, 2021 and lost all the emails of all its customers, which raises serious questions about its reliability.
