IF YOU USE COCK.LI AT ALL IT IS ABSOLUTELY IMPERATIVE YOU CHECK THE WARRANT CANARY DAILY AND BE PREPARED TO MOVE ANY ONLINE ACCOUNTS YOU'VE MAID WITH EMAILS FROM THEM SOMEWHERE ELSE
They are not going to release ANY information to any government but they're being harassed by CISA and if it gets to that point they will just nuke the entire service entirely.
If there are any other good anonymous email alternatives please post them here
