mail body load very slow

I have sync my gmail account, with downloading mails for offline use.

The message body of the new messages gets loaded very very slow, the net connection speed is good but the software lags.

Hi, i ave the same problem. I have solved, in a part, the problem cleaning a lot of unread messages and oldest messages.
Seems that Em Client have a bug with massive mail reception.

Hello,
does this issue happen with the latest version?
Do you have any firewall or antivirus that could block eM Client’s connection? Try adding eM Client to exceptions in these programs and see.
Are there any error messages?

Regards,
Olivia
