A/B Email Test

[tjackson]

When sending an email with an A/B test, do you have have to send both versions seperately or will it automaticllay send both A/B versions at the same time?

Thanks

Hi @tjackson

If you are using the AB testing feature in HubSpot Marketing Pro or Enterprise, the system will automatically send each variation simultainiously to a segment of your audience, monitor the performance for a set time, then send the winner to the remaining contacts. 

If the audience size is less than 1000, HubSpot will send each version to 50% of the audience, rather than test then select a winner, as the sample size is to small to be confident in the result. 

Hope this helps.
