The customer bulk-imported readers as part of onboarding a large user base. A portion of them have not activated their accounts. With no bulk-send option, the customer would have to manually trigger "Send Activation Email" individually for every unactivated reader, which is highly tedious and doesn't scale for accounts with large reader lists.
Add a bulk action to select multiple readers (e.g., via checkbox selection or filter, such as "not yet activated") and send activation emails to all of them in a single action, similar to existing bulk actions like deactivate/delete/convert to user.
