How do YOU track Email Conversions?
I've been using Marketo since 2014, and I've always tracked Email Conversions the same way -- by using a Smart Campaign that listens for one of 3 actions: A change to "MQL" field value for Contact Status, the same for Lead Status, or the lead being Added to an Opportunity. The other filter I add is "was sent email within 7 days" -- that way I know what email they converted from. However, this has failed me as we we have other email sends within 7 days that the lead could have had any of these triggers fire for, while being sent the same email within 7 days.
So, for example:
Lead gets sent Nurture Email 1 and does not reply to the email, so no conversion.
But, 4 days later, Lead receives Webinar Follow Up Email and replies to the email, so our Lead Qualification Specialist marks them as an MQL by changing their Lead/Contact Status. Ding! Conversion for Email 1 AND Webinar Follow Up Email, since both were within 7 days.
