Don’t know about conservative, but if you want to keep your email private, here is a good one.
I’ve had a protonmail account for several years and was sending and receiving mail with a patriotic activist organization. All of a sudden, they were removed from my contact list and all the emails I had received from them were deleted.
I told one of the patriot group’s higher ups and they said their managers have protonmail accounts and have had no problems. I told him that protonmail officials may want to keep the patriot group’s email operating so they can follow what they are doing and plan to do and reporting it to ATF? Justice Department? FBI?
