Hey @PJ_FGWC 

Welcome to the community and congrats on your first post, it’s a great question.

In my opinion it would actually be best to set up a flow for your use case. With campaigns, its a one time send and will not address any new customers who are added to your segment. My recommendation would be to set up to A/B Test a Flow Branch.

First set up segment triggered flow > Conditional Split (Random Sample 50%) > Email #1 > Time Delay. It will look something like this: 

This will allow you to easily make sure that 50% of your customers receive the Yes path (Group A) and the other 50% to receive the NO path (Group B). The article I linked above will go into more details on A/B testing the branch. 

Hope this helps!

Hi Stephen, thank you so much for the reply! I had actually thought of this and started building this out...however, it doesn’t seem there’s a way to trigger to a specific segment at a specific date and time...how would you go about doing this?

I would do this via segments.

1. Day 1 Send, do a split test and give each version a different name.
2. After the send, create two segments using message variation filter, where you enter each message variation name into the respective segments.
3. Day 2 send, send separate campaigns to the above two segments you made
4. Day 3 send, send separate campaigns to the segments you made in step 2.

Here is a screenshot of what the definitions would look like for the segments. You would just need to change the message variation name to match the names you picked. 

Hopefully that helps!
