    you guys are the best finally someone is thinking and doing a fantastic job. Expand into a shared desktop and storage, its great. Add a delay on the email out box so not everything goes out at 3 am it can go at 8 am and look normal.
    I love what you do, whole family and company on it and waiting for domain name to be possible but love proton mail all the same. Great amazing job.
    Thank you!!!

    If only we can have a login ID that’s different from our email address – this way it’s less susceptible to hacking.

    Good job nonetheless!
