Email/SMTP

Send HTML-formatted digests and notifications via email.

Quick Setup

Gmail (personal use):

1. Enable 2-Step Verification on your Google account
2. Go to App Passwords and generate one for "Mail"
3. Use smtp.gmail.com:587 with your email and the app password

SendGrid (production):

1. Sign up at sendgrid.com (free tier: 100 emails/day)
2. Create an API key under Settings > API Keys
3. Verify a sender email address under Sender Authentication

Resend (alternative):

1. Sign up at resend.com
2. Add and verify your domain
3. Create an API key from the dashboard

Configuration Notes

• Gmail App Passwords work for personal use and testing. For production volume, use a dedicated email API.
• In n8n, configure SMTP credentials under Credentials > SMTP with host, port, user, and password.
• SendGrid's free tier (100 emails/day) is more than enough for daily digest delivery.
