I’ve been trying to retrieve my free activation license but didn’t receive. My email address is Tried many times but still not receiving it. Thanks

One thing I noticed from your message above is that this is your business email address. 

You cannot use a Free License for business, so the license has probably been blocked, and you will not get reminder of the activation key.

If you want to continue using eM Client for business, you will need to purchase a Pro License.
