Android email access:

Hi, I am trialing emclient on the free version and finding it a good alternative to outlook. I wondered if I upgrade to the pro version I will be able to access emails on my android phone and if this will prevent my inbox becoming full - if so I am in.

Yes. I have eMc on my desktop and use Mymail app on my mobile. When setting up your emc account ensure you use Imap settings

PRO account provides all the same features as FREE, tneither limits your access to your mail on Android though.
If you set up your accounts using IMAP though you will be able to access your messages from all devices.
