== Step-by-step instructions ==
To successfully implement '''1:1 email threading''' in your automations, follow these detailed steps:

1. In a new or existing automation, click the node (+) where you want to insert your first 1:1 email.
2. In the "Add an action" modal, click on '''Sending''', then select the '''Send a 1:1 email''' action.
3. Configure the content and settings of the 1:1 email accordingly.
4. Click '''Save''' to store your first email configuration.
5. Click the node (+) again where you want to add your second 1:1 email.
6. In the "Add an action" modal, select '''Sending''' and choose the '''Send a 1:1 email''' action once more.
7. To enable threading for the second 1:1 email, toggle the '''Send as a reply''' option to green.

8. A '''Replying To''' field will become visible. If there is only one previous 1:1 email, it will automatically be selected. If there are multiple emails, choose the one you wish to thread this second email to from the dropdown options.

   * If you leave the '''Subject line''' blank, the subject of the replying email will automatically be used. If you wish to modify it, be mindful that changing the subject might affect how the recipient's email service provider groups these emails.
   
9. Configure your second 1:1 email with the necessary options as outlined in Step 2.
10. Click '''Save''' to finalize the configuration of this email.
11. You will see that the second '''Send 1:1 email''' action indicates it is “Sending as a reply to...”, confirming that the threading is correctly established.

*Note: These steps provide a basic guide to establishing 1:1 email threading in an automation. You can enrich your automation by adding additional actions, such as '''Wait''' or '''If/Else''' conditions, to control the timing and flow of your emails.*
