Will eM Client get slower with 100,00 emails?

Will eM Client get slower or glitchy once it has over 10,000’s or 100,000’s of emails stored in it? Past email programs used when stop working properly, searching would stop working. Any ideas?

Hi Brian,

We tested eM Client on databases with 500k emails and there was no significant increase in response rate. However, this also depends on used protocols and if the IMAP accounts are set to download messages for offline use.
