In my opinion, the solution provided by Zuzanna is the way to go in your case. But I'll drop some other options just in case:
1- Use send throttling. Send Throttle sends emails during the hours you specify every day, starting the day you send the email until all emails send.
You can use Send Throttling for these reasons:
- To control inbound traffic to a website caused by the interest generated from an email. High inbound traffic can result in server crashes due to too many people visiting.
- To limit the number of emails sent to a particular domain each hour.
2- Use Wait by attribute activity. In this case, you need to do the segmentation outside of Journey Builder using SQL for example.
