on the emails we send to our costumers, we show them a value and this value is increased after some days, when we send them a second email with new value. So, at the automation process we updgrade the value, and we insert %DEAL_VALUE% on the email. So far, so good!
The point is we would like also show the old value on the email, so it would be showed old and new value.
How could I managed it?
