Do I need a tracking code for every email I send?
Not necessarily. Customers use Email Analytics in many different ways, and the strategy around how to collect Analytics data can vary quite a bit. Timing, segmentation and volume all may play a factor in how you might choose to generate tracking codes and analyze your data.
It's important to note that there is a 1:1 relationship between tracking codes and reports/exports in Litmus: if a single tracking code is used in more that one email, all of the data from each send will "roll up" into a single report in the Litmus interface, as well as their associated CSV exports. If a single tracking code is used in multiple emails/sends (or in a template that is used more than once), you will not be able to differentiate one send from another in your reports or CSV files.
If you send a daily campaign, you may only choose to include a tracking code in a weekly or monthly email of your choice. Consider what you'd like to learn by using Email Analytics, and plan your tracking code usage accordingly. Choosing representative samples for strategic analysis may be more beneficial for tracking trends, unless the content or type of the mailings are changing dramatically. Using one tracking code per mailing or segment type each month is common for noting trends over time in audience behavior.
In individual level CSV reports, a date/time stamp is included on each hit, and reports combine multiple emails together if one tracking code is used in multiple emails. You can also add an additional parameter (such as a campaign ID) to your tracking codes.
