# Reminders About Outstanding Payments
## E-mail payment reminders
E-mail payment reminders are sent automatically to clients who have outstanding payments.
### Enabling payment reminders
Go to *Settings* → *Communication*. In the *Information for clients* section, switch the toggle next to *E-mail payment reminders* from No to Yes.
A pop-up will appear showing which participants (active and inactive) currently have arrears.
Click *Enable reminders* to confirm and start sending reminders, or use *Check participants* to review the list of clients with arrears first.
### Configuring the reminder schedule
You can set the day and time when the reminder is sent. Click the grey pencil icon next to the toggle to open the configuration options.
If you have online payments configured, a payment link will be included in the reminder automatically. If your clients cannot pay online, you can add your bank account number or other payment details to the message content instead.
## SMS payment reminders
Once the e-mail reminder is enabled, an option to also send automatic SMS reminders will appear. The SMS reminder does not include a payment link — it notifies clients that the payment details are in the email. Click the chat bubble icon (next to *Yes*) to preview the SMS message content.
{% hint style="info" %}
SMS payment reminders are sent using the SMS points on your account.
{% endhint %}
## Delivery summary
After automatic payment reminders are sent, you will receive a **notification**. Click it to open the **email campaign summary**, where you can see who received the reminder, what the message content was, and who the messages could not be delivered to.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://help.activenow.io/en/billing/automatic-payment-reminders.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
