**Your software**  
My Mautic version is: v4.4.3  
My PHP version is: PHP Version 7.4.3  
My Database type and version is: 8.0.36 pdo\_mysql

**Your problem**  
My problem is: I’m trying to create an a/b test to see if it’s better to send emails at 12pm or 3pm. However, whichever email I set at 12pm (variant or original), sends all emails.

These errors are showing in the log: No error

Steps I have tried to fix the problem: Traffic weight is always set to 50, and I have tried setting the variant to go first and the original. The first one always sends everything.

Hello @fcamara,

When you set up an A/B test for emails, you can choose when to start and end the test.

![image](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/a/aa9f6ed84e366f07b895229f46e2212591873e21.png)

However, A/B testing is used to compare different versions of an email, in the same campaign, not to determine the best time to send emails.

To find out if sending emails at 12 PM or 3 PM is better, you need to create two separate campaigns - one for each time. This will allow you to measure the performance for each time slot accurately.

Best regards,  
Ricardo

Thanks for the help, @ricfreire!

I’m not sure I understand. I want to A/B test a Segment email send time, I should’ve said it sooner. So you’re saying this is not possible?
