Greetings, I’m new around these parts and have been thinking of kicking iCloud/Gmail to the curb as far as email, calendar and contacts go. I currently use both services, but I’m getting tired of being the product, the flood of advertising and the stress that relying on multinational tech companies brings into my life. I’ve considered switching to either Proton or Tuta for these services, but I’m not sure of what advantages and disadvantages each one brings to the table. My requirements are fairly simple:

• The service I choose must use end-to-end encryption by default
• The service I choose must work on iOS, Linux and the web
• The service I choose must not make it difficult for those contacts of mine not using the chosen service to read any messages I send to them
• The service I choose must offer a free option so I can get used to using the chosen service
• The service I choose must offer an option to use a custom domain name if I choose to subscribe to a paid plan as I might want to use the chosen service for any personal domains I own
• Any applications the chosen service provides must be fully accessible to screen reader users as I am blind and rely on a screen reader to use my devices

What I’d like to know is what are the benefits and drawbacks of both Proton’s and Tuta’s services, how affordable each option is and what other people’s experiences are with each service. Any insight the community can offer would be helpful to me in making this decision.

Thanks in advance for reading this and offering your feedback.
