Hi Vedant,

How long have you been using eM Client? I think you can try it for 1 month…after that you will need to buy it or apply for a free license.

Regardless of the number of accounts you’re using, you need to have a license key, whether it is a free license obtained for home/personal use only or a purchased license for commercial/business use, you have to obtain one after the initial 30 day free trial.
Go to our website for more information about pricing or to register a free license.

Thank you,
Paul.
