I have been using the A/B feature for my previous client perfectly , however with the new requirements I wish to seek guidance on the below queries.
1) Instead of using 2 separate deliveries to set up a campaign and use the tracking information for targeting the winner, can this be done using a single delivery by implementing dynamic subject lines. 2) It usually takes a lot of time in our instance to get the tracking information . Is there a way that we can expedite the tracking process or what is the exact time when the tracking information is available to use.
3) Are there any challenges that may arise for using recurring deliveries for creating an A/B test campaign.
