Switch to FairEmail, you won't regret it.
It's missing a rich text editor, (if that was something you used), but you gain in privacy, encryption and a trustworthy developer with a long history focused on privacy and extremely functional apps, (also in app filtering if that's you're thing, auto-responders and more).
It really is just much better and it makes so much more sense once you delve into it, it's probably one of the most intuitive, if not the most intuitive email apps on Android for intermediate users and above, (bit of a steepish learning curve for beginners but that's offset by decent documentation).
You can purchase outside the Play Store too so you're not tied into that particular ecosystem and the annoyances of it.
It's also on F-Droid but the recommendation is to use the GitHub releases.
I've used both K-9 and FairEmail. I prefer FairEmail.
If you have privacy concerns with auth2 in FairEmail you can manually setup an account and use IMAP or POP.
FairEmail attempts to recognize and disable tracking images.
>K9 has options for disallowing any picture or graphical or HTML content
One of my favorite things about FairEmail is the developer, Marcel Bokhorst. I contacted him about a bug I found in Audio Recorder that wasn't working as expected with FairEmail and he successfully got both apps updated in 24 hours. I made a suggestion on making a small adjustment to how delayed messages are sent and he said he would consider it as a low priority item, he implemented it in one week. He responds to most emails in one day, updates/improvements are pushed out several times a month, and the Pro version of FairEmail is a "buy once" monetization model - totally worth it.
Have you tried either of my suggestions, (FairEmail does not require Google Play to purchase the pro version https://email.faircode.eu), K9 is totally free.
In terms of calendar I can't think of a way to sync them without using Google Services unless your Google Workspaces account is compatible with CALDAV, in which case you can use DAVx5.
Beyond that you'd likely have to cobble some kind of sync to a CALDAV provider, and then use DAVx5 to sync the whole thing.
If you are using gmail as your email provider, then FairEmail isn't going to protect you again Google, but it may be able to help protect you against 3rd parties. See the "Privacy features" listed on their website.
FairEmail is another option if you appreciate open source.
If you are willing to pay, then the best options are Nine, AquaMail, and MailDroid. MailDroid Pro happens to be on sale right now.
Just be aware that these emails are not simply plaintext, so a link could lead you anywhere and so would personally never click on a link from an email!
Also, by loading the images and other external resources it can be precisely tracked when and how often you open an email (and a lot of other information as well).
Something like this app (https://email.faircode.eu) would be advisable to be used as a mail client but so far there is no good alternative for iOS.
Kind of unrelated to your post but I figured it might be interesting to someone.
The latter. It's open-sourced but the developer just archived the repo and and said he wouldn't continue developing it. It can still be forked of course. The developer explains what happened here https://email.faircode.eu/
Nope, and I never claimed to have. my projects have been much smaller. with little to no users. It doesn't change how passionate I was about those projects and how various setbacks etc caused burnout.
If you add to that the pressure of supporting the app for thousands of users, the feature and bug issues, the distribution, responding to ungrateful and demanding users etc. Even more reasons for burnout. Its an assumption because I've never experienced those burdens as a solo developer but I can imagine how Marcel is feeling right now.
He has left it the app up by the way, its still available on github, its still available on f-droid. The source code is public. There's even an official way to get the premium features for free here.
If there was anything shady going on I'm sure one of the many contributors would notice...
Oh damn, I didn't know! For everyone like me who has missed that as well, here's what's written on the dev's website: https://email.faircode.eu/
"All my projects have been terminated after Google falsely flagged FairEmail as spyware without a reasonable opportunity to appeal. There will be no further development and no more support."
Such a shame that Google kills FOSS projects with actions like these. I've been using fairemail for years and even donated some money to the dev. It seems as if we need to look for other clients in the long run. In the short run it will work just fine, just like it did for the past years.
For a mail app, I would suggest FairEmail – a FOSS and privacy focused mail application with many great fearures. I use it everyday and must say that I’ve never used a better Android mail client than this one. The app is available on F-Droid, PlayStore (which obviously isn’t an option for a FOSS phone) & GitHub, for more info see https://email.faircode.eu
Did you check the notification channels under Notifications? See if there are multiple channels for each account.
Do you have multiple emails linked to either email in their respective online account settings? i.e. one set as a recovery email, etc.
I converted to using FairEmail (open source, highly customizable) after I started swaying away from Google Services - and their major issues/tracking, aside from Fi 😂
Try FairMail (https://email.faircode.eu/). I've used BlueMail before switching to FairMail. BlueMail is excellent. There was only one reason to switch: FairMail is opensource. FairMail is excellent too (I paid for premium features though).
You could use Fairemail if you are on Andoid - this is an email client that has an optional pin code input to open the client. Even if someone has your phone, they can't start the app to change the password.

In terms of calendar I can't think of a way to sync them without using Google Services unless your Google Workspaces account is compatible with WebDAV, in which case you can use DAVx5.
Beyond that you'd likely have to cobble some kind of sync to a Web DAV provider, and then use DAVx5 to sync the whole thing.
Almost all features are free to use, only a few advanced/convenience features need to be purchased. Please see here for a list:

The pro features are there for long term maintenance and support. There are already enough abandoned apps!
FairMail by Marcel Bokhorst, the creator of (among others) NetGuard.
Open source.
If you buy it, I suggest using a non-google download and paying him directly (preferably via SEPA if you are in europe), so he gets more money than having to give google and paypal 30%: https://email.faircode.eu/donate/
For mail on my phone I use https://email.faircode.eu/ which is an opensource mail application developed by a Dutch fellow. It handles gmail labels perfectly, has a sensible donation/pro features model, and I get updates on Fdroid often. This is so far the best email client I used for a phone. Full feature, very nice UI design, good functionality. Beats K-9 and many others I tried. Completely FOSS, with the dev working on it actively. I cannot contrib, so I threw some money at him. Well spent. Give it a go and spread the word if you like it!
On laptop, well, I use Thunderbird. I guess claws-mail would have plugins that help you with this, I just never bothered to set it up (comes pretty barebones by default, if I remember correctly).
I hope this helped.
This is an open source project giving people an option to pay without Google play. Instead of enthusiasm, ITT:
Vote with your wallet. I gladly pay to support those initiatives
FairEmail is mostly good, based on security and functionality, not on looks. It receives emails instantly which is great. You can search emails on server, nice a well.
I bought it when it came out, was 7$ now down to 1 (give more if possible?) Pro features
FairEmail is another good open source email app:
The best commercial email apps are Nine, AquaMail, and MailDroid. All have free versions or trials.
MailDroid is the least expensive of these, currently on sale for $4 in the US. Nine is great if you use Microsoft email and want Outlook-like features on Android. AquaMail also great but they really jacked up the price recently. If you like it, you might want to wait for a sale.
