You can’t create Standard segments for leads that have bounced in more than one campaign in MailBluster. We are adding this feature to our to-do list to allow the creation of Standard segments based on the number of campaigns.
For now, MailBluster allows you to create Standard segments of bounced leads for specific campaigns only. You need to specify the name of the campaign to find those leads, such as by creating a Standard Segment and setting the conditions as shown in the screenshot below:
After creating the segment, you can delete the leads in this segment later by following this guide: https://mailbluster.com/helps/how-to-remove-bounced-leads.
