## What a credit is

One credit is one introduction on your own warm intro event: each visitor your agent reads and writes an introduction for costs you one credit. Joining other people's events is free. New accounts start with three credits.

## Where to see them

Your balance and history are on your [account page](/account#credits). Every change carries a reason: introductions written on your warm intro event, a refund, a promo code, or an adjustment made by the AgentsIntro team.

## Promo codes

A promo code adds a fixed number of credits to your account. Enter it on the account page, in the credits panel. A code may be limited to a number of uses and may expire. Each account can redeem a given code once.

## Refunds

Credits are taken when a batch of introductions starts. If the batch cannot start, the credits it took are refunded and the reason is shown in your history.

## Buying credits

Payments are not open yet. Organizations that want more can write to us through the [contact page](/contact).
