# Auto-refill and credit alerts

> Have Emailit buy credits automatically when your balance runs low, choose who gets refill, low-balance and invoice emails, and understand the refill rules.

Auto-refill buys credits for you when a workspace's balance drops to a threshold, so sending never stops because you forgot to top up. The same card also controls the low-balance alert and who receives billing emails. This page explains every setting.

## Before you begin

- You're an **Admin** of the workspace.
- The workspace has a default card. Add one under **Payment method** on **Workspace → Billing**. See [Invoices and billing details](/docs/billing/invoices/#payment-methods).

## Turn on auto-refill

1. **Open the Auto-refill card.** Go to **Workspace → Billing**. The **Auto-refill** card is on the **Workspace plan** tab.

2. **Set the refill amount.** Use **Refill amount** to pick a whole-dollar amount from $20 to $500. The control shows how many credits that buys on your plan.

3. **Set the threshold.** Enter the **Minimum credit threshold**. When your balance is at or below this number, Emailit refills.

4. **Choose who's notified.** Review the email switches and enter **Notification emails**, separated by commas.

5. **Save and switch it on.** Select **Save refill settings**, then turn on the switch at the top of the card. The switch saves as soon as you flip it.

## Settings and defaults

| Setting | Default | What it does |
| --- | --- | --- |
| Auto-refill switch | Off | Turns automatic purchases on or off. |
| **Refill amount** | $20 | Charged per refill. $20 to $500, whole dollars. Credits are added at your plan's rate. |
| **Minimum credit threshold** | 10,000 | Refill when the balance is at or below this many credits. |
| **Email when a refill is about to happen** | On | Sends "Emailit is about to auto-refill your credits" before the charge. |
| **Email when a refill happens** | On | Sends "Emailit auto-refilled your credits" with the amount charged and credits added. |
| **Alert when running out of credits** | On | Sends "Emailit credits are running low" when the balance reaches the running-out threshold. Works even with auto-refill off. |
| **Running-out threshold** | 1,000 | Balance at which the running-out alert is sent. |
| **Email the same addresses when a new invoice is issued** | On | Sends "New Emailit invoice" with a link when an invoice is paid. |
| **Notification emails** | Empty | Who gets all of the emails above. If empty, they go to the workspace's billing email. |

The balance Emailit checks is the same as **Credits remaining** on the **Billable usage** tab: included credits left this month plus purchased credits.

## How refills work

- **Checks run in the background.** Emailit checks balances regularly, not on every email, so set the threshold high enough to cover your sending between checks.
- **One refill per hour.** After a refill, the next one can happen an hour later at the earliest. If you send more than one refill's worth of credits in an hour, raise the **Refill amount**.
- **The default card is charged.** The charge uses the workspace's default card without a checkout page. If there's no default card, nothing is charged.
- **Purchased credits.** Refilled credits are purchased credits. They never expire and count toward the [first credit purchase](/docs/billing/credits/#buy-credits) rule on Pay as you go.
- **Failed charges.** If the card is declined, no credits are added. Update the card under **Payment method**.

## How alerts work

The running-out alert is sent at most once every 24 hours per workspace, so a low balance doesn't flood your inbox. Set the **Running-out threshold** above your typical daily usage to get a day's warning.

With auto-refill on, a sensible setup is a running-out threshold below the refill threshold. You then only get the alert if a refill fails or can't keep up.

## Example

A Pro workspace sends about 20,000 emails an hour at peak. With a **Refill amount** of $20 it gets 200,000 credits per refill, which covers about ten hours of peak sending, so one refill an hour is plenty. A **Minimum credit threshold** of 50,000 leaves room for sending between balance checks.

## Turn auto-refill off

Turn off the switch at the top of the **Auto-refill** card. Credits you already bought stay in the workspace.
