I've been using #KMail for years, but as part of the larger #Kontact app (which gives you Outlook like functionality (contacts, calendar & more)). The interface has not changed over the years.
The idea of identities been different to the accounts allows you to (for example) separate work and personal. For example with each identity you can set up a different signature, and which email address / SMTP server it uses. However the setup for this does need work and is initially confusing for new users.
Note I recently tried #Thunderbird and hated it - I use keyboard short-cuts and TB's were browser-based and not email based (eg CTRL-R / CTRL-U for mark read / unread). I found no way of changing them while being #KDE, that is always an option in #Kmail.

Ah ben moi ça fait des années que je suis sur le 2€ #freemobile avec un #smartphone. J'ai du wifi ou je demande aux proches de partager leur 4G... et pour le reste du temps, les 50 Mo me suffisent pour aller chercher mes entêtes d'emails et en lire qqs uns avec #kmail, l'appli #citiz, et éventuellement un transfert avec #wise.

A noter : quand on va à l'étranger, on a droit à 50 Mo de plus !

Et pour limiter les apps, sur mon vieil Android 6 il suffisait d'être en mode "data saving".

#Update

Yesterday I started the #mail #migration using #KMail #import tool and targeting #thunderbird profile folder.

Please note that I use Thunderbird since 15 years as my favorite mail client, and I used to have 5 or 6 accounts (plus my daugthers' accounts for school). So the amount of emails to migrate, even though I'm convinced that only the essential was left, was huge... ~92 GiB!!!

Now... I feel I need to reboot my #Debian, that looks a bit unstable after 1 full day spent crawling and indexing old emails... and then start Kmail... wish me good luck!

I'm really sorry to hear this. I can tell that it serves me well, but this doesn't help you. You will certainly find a good alternative. Any plans already?

@lunkki #Tuta-tili on nyt luotu. Uutta sähköpostia en tosin olisi tarvinnut, oma osoitteeni on ollut jo parikymmentä vuotta webhotellissa (joka on pariin kertaan vaihtunut).

Tuta tarjoaa sovelluksen #Android'iin ja jonkinlaisen (#AppImage'na pyörivän) myös #Linux'iin. Jälkimmäinen arveluttaa, mutta kokeillaan. Kytkemisestä käytössä oleviin ohjelmiin (#KMail, #Kontact tai vaikka #Vivaldi) ei ilmeisesti kannata uneksia.

@opensuse sono nuovo e sto cercando di crearmi un ecosistema digitale europeo ma, per rimanere con voi di #opensuse ho dovuto scegliere la #tumbleweed a causa di servizi non compatibili con le versioni delle applicazione presenti nella #leap. Il più eclatante è la compatibilità tra #microsoftoutlook e #kmail.

@benlk I use #kmail since I can remember, with the exception of the time when they were fighting getting #akonadi to work - which it does since many years at this point of course. A workhorse of my life :)
