Important Notes
-
Ensure the Enable review email option is turned on in the Custom HTML tab before sending emails.

Make sure your HTML code is clean and properly structured to avoid rendering issues across different email clients.
-
Test your email design using the Send test email option before activating it.

Keep your email responsive and mobile-friendly, as most users open emails on mobile devices.

Avoid using unsupported scripts or advanced CSS that may not render correctly in email clients.

Ensure all links, buttons, and call-to-actions are working properly.
-
Use clear and engaging subject lines to improve open rates.
- Keep the email design simple and focused to improve readability and conversions.

For reminder emails, avoid sending too frequently to prevent customer fatigue.
