How to add subscribers to an automation (workflow)

A workflow can only be triggered after it is activated. So when you activate a new workflow, only new subscribers who meet the trigger conditions will enter it.

However, you can also manually add existing subscribers to any workflow, regardless of the trigger type. This allows you to include subscribers who joined your audience before the automation was activated or to re-enter subscribers when needed.

The Add subscribers action is available in several places:

Via the three-dot menu on the Automations main page and in Automation reports.

From automation previews.

In the left-side Stats panel inside the workflow editor.

  1. Open your workflow and make sure it is enabled.

💡 Subscribers can only be added to active workflows.

  1. Click Add subscribers located in the left-side Stats panel.

  2. Choose one of the following options:

  • Chosen subscribers: Enter one or more email addresses.

  • Specific group: Pick a group to add multiple subscribers at once.

  1. Decide where the subscribers should begin:

  • From the Start of automation

  • From a Specific step

  1. If you choose to add subscribers to a specific step, choose the Step type and Step details.

Keep in mind, manually adding subscribers to a workflow bypasses trigger checks. In order to add any subscriber to the flow, the system won’t verify if a subscriber meets the original trigger condition.

However, steps inside the workflow are still respected, ensuring subscribers only move through relevant paths.


When you enable a workflow, you may see a pop-up to Add existing subscribers. This only refers to existing subscribers who have not yet entered the workflow and also meet the trigger condition.

You can choose between:

  • No, only add new subscribers: Previous subscribers will not be added to this sequence, only new subscribers who meet the condition.

  • Yes, add them to the start: Adds previous subscribers who meet the condition to the beginning of the workflow

  • Yes, add them to a specific step: Add previous subscribers to any step in the automation. Here, you can specify which step to add them to. 

If you want to manually re-add subscribers who already finished the workflow:

  1. Head to the Automations page.

  2. Click on the View report button of the workflow.

  1. Select the Activity tab.

  2. In the dropdown menu, choose the Completed category to view all subscribers who have finished the automation. This method will also work for those in the Canceled or Failed category.

  1. Click the checkbox next to the email address to select the subscriber.

  2. Click on Actions above and select Re-add to the sequence.

  1. Add the subscriber to the last step they completed, or to any other step, and click Confirm.

Currently, it is only possible to manually add existing subscribers to workflows by using the trigger when subscriber joins a group. It is not possible to manually add any subscriber to any other type of workflow.

A workflow can only be triggered after it is activated. So when you activate a new workflow, only new subscribers will trigger it. Existing subscribers who have been a member of the trigger group before the workflow was activated will not be triggered automatically. To trigger them in the workflow, you will have to manually add them.

To manually add an existing subscriber, open the workflow in edit mode and click on the link Add subscribers to workflow on the right-hand sidebar.

You should see the number of existing subscribers who are part of the trigger group but have not yet been added to the workflow. Click on Add if you want to trigger them.

Note: This option will only appear if there is at least one existing subscriber who is a member of the trigger group but has not been added to the workflow.

If this option doesn’t appear, it will be due to one of the following reasons:

  • All members of the trigger group have already triggered the workflow.

  • The trigger of your automation is something other than When a subscriber joins a group.
