My wife is very stubborn and hates it when her email site (gmail) changes the layout- are there any email services for people like her, that don’t ever change their layout?
Elm has stayed pretty consistent. Use that with POP or IMAP on gmail and you are set.
Use an email client (Thunderbird or similar) and set it to go fetch your POP mail out in Internet Land. Advantage: you can decide not to update the client ever again, so it will always look the same. Disadvantage: you will have to set the client up on every computer that you want to access the email account from.
softhome.net has not updated their web client in at least a decade but it is fairly primitive and if she has a high volume of email, the free account may not be enough. Also, you will have to check to see if they are taking new free account holders.
