Do I need coding skills to use these templates?

Not necessarily. Our templates are production-ready. You can simply copy the HTML code and paste it into your email sending service (like SendGrid, Mailchimp, or AWS SES).

Will these emails look good on Outlook?

Yes. We rigorously test our templates for compatibility with all major clients, including the notoriously difficult Outlook versions, Gmail, and Apple Mail.

Can I use these for commercial products?

Yes! All templates on this page are open-source and free for commercial use in your SaaS, app, or newsletter without any attribution required.
