You should ditch yahoo.com, gmail.com, and hotmail.com ASAP and start using protonmail.com. Protonmail.com is the best email.com you can use even though some functions of the email are still rudimentary. This email allows to transfer your old emails from those mainstream emails.
你應該盡快放棄 yahoo.com、gmail.com 和 hotmail.com，並開始使用 protonmail.com。 Protonmail.com 是您可以使用的最好的 email.com，即使電子郵件的某些功能仍處於初級階段。 該電子郵件允許從那些主流電子郵件中轉移您的舊電子郵件。
Gmail.com and many other email services may not be as good as you thought if you value your personal privacy. They are required by some government to retain a hard copy of all your emails which can be used by the government in case it needs to make a case against you. The content you communicate may not violate any law or regulation, but your behavior for instance what your said in your email can be used to profile your character. If you have said something politically incorrect or said something negative to vent the emotion you experienced because of some life hardship, then you may be in trouble already.
Pm.me or protonmail.com offers a password-protected email delivery system. The content is secured and the email recipient needs a password to unlock the email which is hosted in a protonmail.com server, which is located highly secured in Switzerland. (Switzerland will not send your emails to any government because its law is most friendly to your privacy). You can set up the deadline for the recipient to fetch your email. After that deadline, the link will disappear and protonmail.com will delete the email from its server leaving no trace of anything about your email. Even protonmail.com does not have a means to have a peek of your email. This is different from gmail.com and many others which keeps everything you wrote and sent to the recipient.
Sign-up is free of charge. Certainly you can pay protonmail.com to have more resources and functions for your protonmail.com email address.
