Slow to Send Email!

I reinstalled eM Client and now when I send email it takes a long time for the upload. New email comes very quickly. Suggestions?

we are sorry to hear that. It is caused by some transactions at local database. We are working hard at some speed optimalizations momentarily. But we need to tune and test it little more before we can make it public with the next release.

Does it display some errors or it’s only slow?
