# How do credits work? Personal Email, B2B Email & Phone Waterfall Enrichment

# Understanding Credits and Enrichment in LeadDelta
LeadDelta helps you unlock more value from your network through contact enrichment. Here's how our **credits** system works, how to use it, and what to expect when enriching emails and phone numbers.

## 🔍 What is Enrichment?
Enrichment means we try to find **verified contact details** (like personal email, business email, or phone number) for your contacts using a **waterfall methodology, **we go through multiple vendors and data sources in a smart, layered way to find the best data available.

|| We only charge you when we find a verified result.

## 💳 What Counts as a Credit?
Here’s how credits are used:
* **1 Business (B2B) email found** = **1 credit**
* **1 Personal email found** = **3 credits**
* **1 Phone number found** = **10 credits**
> 💡 Even if we find multiple emails or phone numbers for a single contact, we’ll only deduct **once per type**—you won’t get double charged.

## 📦 How Do Credits Work?
You can get credits by:
* Subscribing to a **monthly** or **annual** plan, or / and
* Making a **one-time purchase**

Credits are flexible and can be used however you choose—just emails, just phones, or a mix of both.

## 🔁 Do Credits Expire?
Yes, but the expiration depends on how you got them:
* **Monthly subscription**: Credits are valid for **2 months**
* **Annual plan**: Credits are valid for **12 months**
* **One-time purchase**: Credits are valid for **3 months**
Unused credits automatically roll over within these timeframes. If you run out, you can always top up with more.

## 👥 Are Credits Shared?
Yes. Credits are shared across all members in your **Workspace**. Every teammate can use the shared credit pool as needed. (Note: Setting individual limits per teammate is not yet available, but it’s on our roadmap.)

## 🛒 Need More Credits?
No problem. You can:
* **Upgrade/downgrade** your plan anytime (you’ll get the new credits instantly)
* **Buy more credits manually** on top of your subscription
* **Renew early** to reset your subscription and receive new credits right away

## 💡 TL;DR
