Go to CRM → View Contacts → Select a Contact, then open the Automations tab.
Here, you can view what automations (or drip campaigns) this contact has been added to.
To add the contact to an automation, click the “Choose…” box next to “Add to Automation”.
Then, scroll and select (or type in the box) which Automation you want to add this contact to.
Once you’re done, click the blue + Add button. Alternatively, you can select Schedule Start Date, which will start the automation at a later time of your choosing.
If the Automation has a time delay (according to how you set the Automation), you can click Send Now to skip the delay and send it immediately. If not, your Automation will send it at the Scheduled Time.
Click the cancel button next to Status to cancel the automation.
