With LeadBI you can create an automation starting from one to one email contact, send manually. Insert the name, the Trigger Email Contact (Sent Manually), the maximum number of times this automation can execute for a contact, the conditions (optional) and continue.
Subsequently send one to one email to your contact, for example a B&B introduction.
You can continue with the next action and assigning a tag clicking on actions.
Set up a condition, that is wait that the user opens the email within 10 days.
If the user opens the email within 10 days, you can send a notification to your email address.
So you have set up the automation!
