 # AhaSend Email Integration Status
 
-## Current Status: ⚠️ Configuration Issue
+## Current Status: ⚠️ Domain Verification Required
 
-The notification system has been successfully implemented with AhaSend integration, but the API is currently returning "invalid credentials" errors.
+The notification system has been successfully implemented with AhaSend integration, but the API is returning "invalid credentials" errors. This is likely because the sending domain needs to be verified.
 
 ## Configuration
 
 ### Credentials (Configured)
 - **Account ID**: `8a14f9a5-6e6d-47c9-b5d6-a687265b36a3`
-- **Secret Key**: `aha-sk-A0c9WOA8cs3RpvkAGwHOP9o6pHx-gLTUki1gSWVeC_6kd86-Npn077zta-rvg9oo`
-- **API Endpoint**: `https://api.ahasend.com/v1/email`
+- **API Key v1**: `pxZ2d30PIqTl6Uj7p6g3o0uez2AacMaOstKCTcj9MTIrNEBvhikgvyAARUTvXAcA`

 4. ✅ Verified payload format matches API expectations
 5. ✅ Tested different endpoint paths
 
-## Possible Causes
+## Most Likely Cause: Domain Verification
 
-1. **API Key Not Activated**: The secret key may need to be activated in the AhaSend dashboard
-2. **Domain Verification Required**: The sending domain (`beachlitter.ie`) may need to be verified
-3. **Account Status**: The account may need additional setup or verification
-4. **API Documentation**: The API format may differ from what we're using
+**The sending domain `beachlitter.ie` needs to be verified in AhaSend before emails can be sent.**
+
+### How to Verify Domain
+
+1. Go to https://dash.ahasend.com/
+2. Navigate to **Domains** section
+3. Click **"Add Domain"**
+4. Enter `beachlitter.ie`
+5. Add the required DNS records (SPF, DKIM, etc.)
+6. Wait for verification (usually a few minutes)
+
+### Alternative: Use a Verified Domain
+
+If you don't own `beachlitter.ie`, you can:
+1. Use a domain you own and have access to DNS
+2. Or use a test email like `noreply@yourdomain.com`
+3. Update `FROM_EMAIL` in `.env` to match
+
+## Other Possible Causes
+
+1. **API Key Not Activated**: The API key may need time to activate
+2. **Account Status**: The account may need additional setup
+3. **API Format**: The payload format may need adjustment
