Use this when you have one specific customer to enrol, typically because they signed up offline, or your team is handling a support request and you want them in the programme straight away. For a list of customers, [upload a CSV](/knowledge-v2/data/uploads) instead. ## Open the Wizard Three entry points all open the same modal: * **Enrol customer** card on the [Customers landing page](/knowledge-v2/customers/browse/customer-list). * A row's **…** menu, then **Enrol in campaign**. * A customer profile's **Enrol in campaign** button (top right). Modal titled Enrol new customer with the Campaign dropdown open Only active campaigns appear in the dropdown. Pick the one that matches the customer's market and segment. If you're unsure, check **Campaigns > Active** to confirm before continuing. Click **Next** to proceed. Customer details form with name, email, and consent checkboxes | Field | Required | Notes | | ------------------------------------------------------------- | -------- | ------------------------------------------------------------------------------------------------------------------ | | Title | No | E.g. Mr / Ms / Dr. | | First name | Yes | | | Surname | Yes | | | Email address | Yes | Must be a valid email. | | This customer is a paying customer | No | Tick if the customer has a confirmed purchase on file. Required if your campaign only rewards existing customers. | | Send referrer registration and forward emails to the customer | No | Triggers the standard Mention Me onboarding emails. **Only tick if you have GDPR consent in writing or verbally.** | Click **Enrol customer** to submit. ## What Happens Next * The customer appears at the top of the list, with **Last activity** set to today. * If you ticked the emails box, the registration email goes out immediately. * The customer is enrolled in the selected campaign only. To enrol the same person in a second campaign, open the profile and click **Enrol in campaign** again. End-to-end flow from clicking Enrol customer to seeing the new row at the top of the table ## Common Issues No active campaigns in your account. Create one in **Campaigns** first. Make sure there are no trailing spaces and the domain is reachable. Mention Me validates the format only, so it won't catch mistyped addresses. Check carefully. The wizard creates a fresh record. If the customer already exists, find them via search and use **Enrol in campaign** from their profile to add them to a different campaign without duplicating. The box enables once an email address is filled in. Only tick it if you have GDPR consent on file. ## See Also Why most customers don't need to be enrolled manually at all.
