Learn how to send a reminder and resolve the issue. In case an affiliate has not selected any payment method (via his [affiliate admin](/guide-for-affiliate/affiliate-admin.md)), the affiliate's payment details will be considered not specified. You can't **Mark as paid/Process payment** if the **Affiliate's payment details are not specified.** In such cases, the system shows a message **No payment method** with a warning icon:

No payment method with warning icon — Payouts tab

You need to contact your affiliate to fill in their payment details in their affiliate accounts. That can be done from within the app by clicking on the **Reminder** button in the **Payments** tab:

If you want to edit the "payment reminder" email template, go to **Outreach** > **Emails** > **Manage emails** > **Payments** > **Payment info reminder** > **Edit it**.
