Frequently Asked Questions

Is Resend only for transactional email?

Yes, Resend is primarily designed as an API for developers to send transactional emails (like password resets or receipts) from their applications, though it can technically send any email type.

What is the main technical difference between Resend and SendGrid?

The main difference is focus: Resend prioritizes developer experience with React-based templates and modern SDKs, while SendGrid is a broader, more established platform for high-volume delivery with extensive deliverability features.

When should I not use an API like Resend?

Avoid a pure email API if you need visual email builders, subscriber list management, marketing automation workflows, or built-in monetization tools without significant custom development.
