    • Domain verification provides the best deliverability

  2. Scheduling Limitations

    • Maximum scheduling window is 72 hours
    • Cannot cancel scheduled emails once submitted

  3. HTML Email Best Practices

    • Test HTML emails before sending to large audiences
    • Include proper DOCTYPE and HTML structure
    • Consider mobile responsiveness

​
Authentication

The SendGrid Email Sender node requires:

  1. A SendGrid API key configured in your Gumloop credentials
  2. Set up in the Credentials page

​
Troubleshooting

  • Emails Not Sending: Verify sender email verification status and API key permissions
  • Delivery Issues: Check spam scores and content against email best practices
  • Scheduling Errors: Confirm timestamp format and ensure it’s within the 72-hour window
  • Category Errors: Verify categories exist in your SendGrid account

By using the SendGrid Email Sender node, you can automate personalized email communications with the reliability and analytics capabilities of the SendGrid platform.
