If you are a Constant Contact user, be sure to grab this quick report before year end.
Constant Contact tracks your list growth and gives you the following options under Contacts > Reports:
last 30 days
last 60 days
last 90 days
month to date
year to date
This is all great information and you should be tracking your list growth and unsubscribes on a regular basis.
However, the year to date data will reset on January 1. So, follow these instructions to grab the data before the New Year.
Log into your Constant Contact account.
Select "year to date" in the drop down on the right.
Take a screenshot of the full window, including the "Growth by Source" information below the overall growth chart. I use Snagit by TechSmith but you can use any screenshot software or just use Print Screen on a Windows machine or Shift-Command-4 on a Mac.
Save your screenshot so you can access the data when you are ready to review it.
