New lead can easily be created from the central dashboard. After creating a lead, next step is to manage the drip campaign for that lead.
For this, first go to the central dashboard and then click on any particular lead.

Lead details page for that lead will get opened.

Inside the lead details page you can easily change the status of the lead. You can also change the email series and timezone.
Email series can be changed as per the changes in the status.
Once the changes are made, click on “Update” to save those changes.
