No…nothing.
My first post on this topic was 06/2024. 17 months later: still the same problem

Hi,
the same problem occured with 10.4.4293 on an Mac M1 Tahoe 26.2. I have 4 Mail acounts. When I start emclient, it shows approx. 900MB RAM. After answering 2 messeges I noticed an increase of memory to 1,7GB. 
Do you have any news on this issue?
kind regard,
Stephan
Signed up to say I’m also having this issue. Every time I close emClient using the x (i.e. hide the window), then start it back up (unhide window), it uses more memory. I have to quit after a while to free the memory, then it’s back to normal (600-700MB).
I’m having the same problem with Tahoe - extremely high RAM usage, and emClient keeps freezing for 10–20 seconds several times
The latest V10.4.5600 for Mac now has improved memory management.

macOS Tahoe Beta 26.6, eM Client V10.4.5600:
Confirmed, this “biting off” memory chunks of 300 MB with every close/reopen no longer happens.
Thanks, good work! An inconvenience is gone…
