I understand that in order for Marketo to track an email opened, user needs to right click and download images which then download the 1x1 pixel bug that is later used to build the pre-canned reports. Do you have control over where the pixel gets placed?
Also, if you create anchor links within the email, check "track link" but don't include mkt_tok, how does that funnel into reporting? Does it get tracked at all?
What are the best practices in using anchor text in emails?
