on selecting a new email to view, the text/content for that email often takes 30-60+ seconds to display in the right hand column.
I have the latest paid for eMClient (version 8.2.1721 (3b3cd99)), Latest W11 Pro with updates, 16Gb i7 Gen 11, 512Gb SSD with plenty of spare room. oh, at least 70-80Mbps broadband download bandwidth.
The email account is usually a domain based Google Account. Is this an issue with the way iMap mail is handled? Double clicking the email, in order to get a full screen, does not speed up the display process.
OK, first thing is you do not have latest version of eMC, perhaps you could consider update here:
Next, maybe you have anti-virus scan of email in background that slow download, try with disable, and perhaps on some systems VPN can cause slow performance.
Last, maybe it is Google, I do not know as I do not use Google for any purpose.
I also use Win 11 Pro on this laptop with with 12th Gen Intel EVO i7 - 32Gb RAM and get instant email display but I do have 945.76Mbps download (just check with Ookla) I have MS Defender, Malwarebytes Premium & Surfshark VPN and never have interrupt or slow download when these run all the time.
