You will need to add the tag **phrasee** (as seen below) in order to see your Epsilon campaign within the Jacquard interface.

Once you have approved your variants, you will see an **Epsilon Integration** button on your experiment summary page. Click that button and the integration drawer will appear on the right side of your screen.

You will do this by first selecting the **Epsilon business unit** and **folder** that your campaign is saved within. Then find your **Epsilon campaign** in the dropdown. Click **Create Test Variants**. This will create the split test variants and populate the subject lines for testing purposes in Epsilon before scheduling.

If you don't see your variants in Epsilon, try refreshing your page.

If for any reason you need to edit your variants or remove them from your Epsilon campaign, you can click **Delete Test Variants** within the Jacquard integration drawer for your experiment. This will delete the A/B variants in your Epsilon campaign and remove the link between the two campaigns. ### Step 4: Schedule your campaign After you have approved your campaign in Epsilon, you’re ready to finalise the schedule in Jacquard. Within the integration drawer, enter the following details: - Date and time you want to send the split test emails - How long to wait prior to sending the winner (Jacquard recommends at least 4 hours) - Campaign end date and time (this is when Jacquard will pull in your final send results) - When to lock the audience for the send - **Note:** If you select **Specific time before deployment**, you will be prompted to enter the hours or days prior (as shown in the images below) - Seed List (optional - this seed list will be added to each variant within your deployment) Click **Schedule Campaign** and your deployment will now be scheduled in Epsilon. If for any reason you need to cancel or change the deployment, ensure you do so **within Jacquard** by clicking the **Cancel** button. This will cancel both the deployment within Epsilon and the scheduled results query in Jacquard.

When the campaign ends, the results of the final send will also automatically be populated within Jacquard.
