# Billing and subscriptions

> Payments, trial, and plan changes

## Limits

**I hit my contact limit**

* You cannot add or upload more contacts until you’re under the limit. Either **upgrade** your plan (see [Billing overview](/en/billing/overview)) or **remove** contacts you no longer need. Unsubscribed and suppressed contacts still count; delete them to free space if appropriate.

**I hit my email limit (monthly or daily)**

* Sending is blocked until the next billing cycle (monthly cap) or the next day (daily cap), or until you upgrade. The app shows usage on the Billing page. Already-queued sends may still go out up to the cap.

**Emails sent reset to zero**

* Usage resets each **billing cycle** (e.g. monthly). The Billing page shows your current period. Resets are automatic.

## Payments

**Payment failed / card declined**

* Update your payment method in the **billing portal**. Open **Billing** in the app and use **Manage subscription** or **Billing portal** (powered by Polar). Add or update your card and retry.
* If the problem continues, contact your bank or use a different card. For subscription issues, contact us at [contact@nudgen.net](mailto:contact@nudgen.net).

**I was charged but my plan didn’t change**

* Refresh the Billing page and confirm you’re in the correct workspace (team). Billing is per workspace. If it still looks wrong, contact us with your account and workspace details.

## Trial

**Trial ended / I can’t send anymore**

* After the trial period, you must **upgrade** to a paid plan to keep sending. Go to **Billing** and choose a plan. Trial limits (e.g. contacts, emails) are small by design; paid plans have higher limits.

**How long is the trial?**

* Trial length and limits are shown when you sign up and on the [pricing page](https://nudgen.net/pricing). The Billing page in the app shows your trial status and end date.

## Upgrading, downgrading, and canceling

**How do I upgrade or change plan?**

* Go to **Billing**, find the plan you want, and click **Upgrade** or **Change plan**. You’re redirected to checkout (Polar). After payment, the new plan and limits apply as per the provider’s terms (often immediately or at the next cycle).

**How do I cancel?**

* Use the **billing portal** (Manage subscription) to cancel. You keep access until the end of the current billing period. After that, you won’t be charged and sending will be blocked until you resubscribe.

**Prorations and refunds**

* Billing behavior (prorations, refunds) is governed by the payment provider’s terms. Check the portal and your plan details. Nudgen does not control refund policy; contact us if you have a specific request.

## Where to see plans and usage

* **In the app:** **Billing** in the sidebar shows your current plan, usage (contacts, emails sent this month, drip sequences), and upgrade options.
* **Live pricing:** [nudgen.net/pricing](https://nudgen.net/pricing) is the source of truth for plan names, prices, and feature descriptions.
