E-Commerce tracking is used to track purchases that have been made as a result of your email marketing. This can be a really useful tool for tracking the ROI for a specific email campaign. There are some important facts to know about how this works, especially with delayed purchases and multiple campaigns.
If a contact makes a purchase 2 days after engaging with a campaign (let's call it 'Great deals #2') and they don't engage (click) with any other campaign in between, the ROI will be assigned to the campaign 'Great deals #2.
If a contact makes a purchase 2 days after engaging with the campaign 'Great deals #2', but they also engaged with either an older campaign ('Great deals #1') or a newer campaign ('Great deals #3'), then the ROI will be assigned to the most recent campaign that was engaged with.
If a contact makes a purchase 8 days after engaging with the campaign 'Great deals #2', the ROI will not be assigned to the campaign. A contact would need to make a purchase within 7 days of engaging with a campaign for the ROI to be assigned to the campaign.
