A/B Testing - Different Send Volumes

Hello,

We have had a few different email programs send a different amount of emails to our A variant and our B variant, and was curious to see if anyone knows why that might be happening. For example, a recent date/time test we ran had 67,000 emails delivered to our A variant, and 41,000 emails delivered to our B variant. This one specifically was a morning vs. afternoon send; this set of leads received their most recent email before this all at the same and day, leading me to believe our communication limits are not the issue. Any ideas would help.

Thanks!

Hi Zack,

Can you please share the A/B test setup that you have used on your email programs? Per my understanding Date/Time A/B test might have been setup in a way that 60% records receives email version-A while rest of the 40% receives email version-B on defined time. For your reference please refer product doc - Use "Date/Time" A/B Testing - Marketo Docs - Product Documentation

Thanks!

Hi Priyank,


Thanks for the reply. The test was setup as follows:

Variant A: Morning Send - May 1, 2019, 8:00 AM PDT

Variant B: Afternoon Send - May 1, 2019, 3:00 PM PDT

Test Sample Size: 50%

Winner Criteria: Opens

The Morning Send received 67k emails, Afternoon Send 41k. My understanding is that 50% of the available leads should have received the test, with each variant getting half of the available leads. My confusion is to why it is skewed in favor of the Morning Send; I figured if comm. limits were the issue, the Afternoon Send would be the higher number, due to more leads becoming available as the day passed.

Thanks,

-Zack

Was there a separate email that went out between the morning and evening that could have affected part of this audience's communication limits?
