Unless your job is international espionage, then rest assured that the contents of your email are safe.
I'm sorry I'm not a professional at this sort of thing, here are my suggestions, please point out any problems or terminology errors.
Download:
Shadowrocket mobile app.
I purchased VMESS IP and set it up in SHadoweocket. It's handy and you can browse any URL afterwards. Use any non-Chinese programme.
Don't worry about content leakage from your Gmail, Tg, WhatsApp, etc. As long as you don't punish the laws of the land (plotting riots, maligning, guns, drugs, money laundering...) , that's all the government cares about, then you are very safe.
I hope you have a great time here and you can DM me if you still need help.
Update: I found a guide on Shadowrocket. You can check it out.
