Or if you have a little more money, there’s the Proton pass which comes with VPN, Email, Drive, Calendar, and Password Manager. All protected under swiss privacy laws. They have a free tier of their drive with 5GB storage so you can collaborate on other people’s documents without needing to pay yourself, and they have a $120/yr US Tier for 500GB for 1 person, and a $288/year US Tier for 3TB for up to 6 people. If you don’t need that much storage and don’t care about anything other than the email, they have a 15GB plan with just email and calendar for only $48/yr US.
This is not an ad, I am a real person with no connection to Proton except a deep respect for their business, and an even deeper hatred for Microsoft
