Gmail and other email providers have a complicated algorithm for deciding when emails belong to the same thread/conversation. The algorithm is explained in this support note: How does Gmail decide to group emails into conversations?.
Auto Followup for Gmail can send emails either in the same conversation or in a new, separate conversation.

To ensure your autofollow email messages stay in the same thread/conversation, do the following:

• Enable conversations in your Gmail as described in the support note How to turn on conversation view in Gmail?
• Make sure the subject of your autofollow email is set to RE: *|SUBJECT|*. This ensures autofollow messages have the same subject as the first email, but with RE: before it.
• Ensure all autofollow email messages are sent from the same sender. Both the name and email address of From should be the same as the first message.
• If you are sending autofollow emails from a different address than your main cloudHQ or Google account, ensure all aliases are correctly set. See instructions here: Send emails from a different address or alias.
• If you are sending autofollow emails from a different address than your main cloudHQ or Google account, ensure that all emails sent to an alias should be forwarded to your email address as described here: Automatically forward Gmail messages to another account
