Yes the link there im tracking on the page(analytics) but how can i track the open rates? Id like to give in a few info on one of my email campaigns. Some Stats: 5000 email list - Sent 4400 ( 600 emails ware not working, got email back stating that delivery was failed.) Its been over 5 hours since blast, and i got over 200 clicks on my squeeze for the double opt in, with a conversion of 42% at subscription. Now id like to test different Subject lines but i need to know the rates on each blast before i continue. Would appreciate any help. Thank you.
