Sent items going to recipients spam account

I am sending emails to other gmail accounts and the ones that are sent through EM Client are landing in the recipients spam inbox.

One reason this might happen is if you are using an automatic signature setup in eM Client. If that is the case, disable the signature and see if that makes any difference.

But a solution might be to just ask the recipient to mark you as a trusted sender (or whatever terminology they use over at Google).
