Yes, followup campaign emails are sent within the same email thread as the original message. You can enter any subject text as a placeholder when setting up your followup campaign.
Before sending the first followup email, EmailBison retrieves the thread information to ensure your message is properly appended to the existing thread.
After the first followup email, you have the option to break the thread and start a new conversation.
However, we generally do not recommend breaking the thread since continuing the same conversation helps maintain context and increases engagement.
