Best Method to Manage Multiple Gmail's Linked to Ebay Accounts?

[HelpNeeded]

I am looking for a method that will enable me to link multiple gmail accounts together into one main inbox so that I can see which ebay accounts have orders as well as easily reply to customer messages from the one inbox (is this possible without compromising your account to ebay?).

The goal is to obviously do this in a way that would not link your ebay accounts to one another.

I have read of recommendations of ReplyManager or Shift. While they seem to be great tools they do have subscription fees and am seeking a free equivalent alternative.


Some other others that I came across is Mozilla Thunderbird and K-9 Mail for android mobile. Has anyone had any success with these? If so how must they be configured to avoid leaking your IP and linking your ebay account?

Is it possible to use the Gmail mobile application to manage these stealth accounts? I have several personal email accounts tied into one large inbox which is pretty handy and would like to know if this method can be "secured" for stealth purposes.

Can I simply add multiple Gmail accounts to the Gmail android app to view the emails received all from within one inbox without worrying about the accounts getting linked?

i've been using Mozilla thunderbird portable for a long time and i have no problems so far I have about 15 active gmail accounts hooked up. Just make sure images are disabled and set it to plain text if you want to be extra careful.

Can you reply to the ebay messages from within Mozilla thunderbird portable without linking the accounts?
