The best way I've been able to handle this is to do an A/B test. Set the test size to 100% and select the two different dates and times from the DATE/TIME a/b test.

Select the winning date like two days out. It won't matter since your test size is 100%.

David, does that actually work? If you do Sample Size = 100%, it will split test the emails 50/50 on Day 1, then re-send the email winner on Day 2. Are you sure you've seen this work where it doesn't double send to the group? Use "Date/Time" A/B Testing - Marketo Docs - Product Docs

Will definitely work if you run a Random Sample on the main list, breaking it into two static lists, then schedule the two separate lists for whichever day is desired. It feels like extra steps but it takes a few seconds to run the setup.

Hi Jacquelyn, David and Josh,

I agree with the Random sample approach. On your smart list use the Random Sample filter, set at 50, and blast.

Then set up a second smart list excluding the members from the first blast.

There appears to be an A/B test for dates now - Use "Date/Time" A/B Testing - Marketo Docs - Product Docs

"The different variations will apply to equal portions of the chosen Test Sample Size.

If you're using a static list, setting the sample size to 100% sends the email to everyone in the audience and the winner goes to no one. If you're using a smart list, setting the sample size to 100% sends the email to everyone in the audience at that time. When the email program runs again at a later date, any new people who qualify for the smart list will also receive the email since they're now included in the audience."

If you are doing a Date/Time A/B test, you can only declare a winner Manually.

Depending on your list type, this may work well (I send using "member of SFDC Campaign" Smart List step).
