Create an Email Client

Step 1: Create a Resend Account

Visit resend.com and sign up for a free account. The free tier includes 3,000 emails per month.

Step 2: Verify Your Domain

Add and verify your domain in the Resend dashboard. This allows you to send emails from your own domain (e.g., noreply@yourdomain.com). For development, you can use Resend's test domain.

Step 3: Get Your API Key

Navigate to API Keys in the Resend dashboard and create a new API key. Copy the key immediately as it won't be shown again.

Step 4: Add to Environment Variables

Add the API key to your `.env` file:

# Email Configuration
EMAIL_FROM="noreply@yourdomain.com"
EMAIL_REPLY_TO="support@yourdomain.com"
NEXT_PUBLIC_APP_URL="http://localhost:3000"
 
# Resend Configuration
RESEND_API_KEY="re_xxxxxxxxxxxxx"

Step 1: Create a Postmark Account

Visit postmarkapp.com and sign up for a free account.

Step 2: Create a Server

In the Postmark dashboard, create a new Server. A Server in Postmark represents an application or environment (e.g., Production, Staging). Give it a descriptive name.

Step 3: Verify Your Domain

Add and verify your sending domain in the Server settings. Postmark will provide DNS records that you need to add to your domain. This is required for sending emails.

Step 4: Get Your Server API Token

In your Server settings, find the "API Tokens" section. Copy the Server API Token. This is what you'll use to authenticate API requests.

Step 5: Add to Environment Variables

Add the API token to your `.env` file:

POSTMARK_API_KEY="your-server-api-token-here"
