I understand that you want the feature but, while you are waiting for a feature that may never be developed, you don’t have to do it the hard way. You now have two options to make it easier for you to accomplish this task:
- Sort by status and delete each block of users with the status you don’t need.
- Filter by a column by cell content to select the users you want so you can export/copy them.
Also, there are more options which might help you:
Import the user list into a mailing list manager or other tool that is designed to work with email addresses. That way you have access to other features that are useful when sending regular emails. Also, your email service may provide email list management features. This is normal for transactional email providers like Mailgun.
Use the Data Explorer plug-in (as a hosted customer you have to be on a high enough plan) to create a query that selects the users you want to export. Here are an example where email addresses are selected:
Users who voted for a feature
Export group members
Pay for a plug-in to be developed.
If you are sending only to users then consider using groups to select users and send personal messages instead of emails.
FYI, I think that this feature will be a very low priority because it is so easy to accomplish the same result with mundane spreadsheeting skills. This feature would only be needed if there were some major difficulty like having a user list that was too long to fit in a worksheet. But the current limit for rows/records is 1,048,576 for both Microsoft Excel and LibreOffice Calc.
