Resend & React Email Integration FAQs

Question 1

Can I use this skill to send emails directly from the frontend?

Accepted Answer

No, this skill enforces server-side sending only. Exposing your RESEND_API_KEY to the client-side creates a critical security vulnerability that allows others to send emails from your account.

Question 2

How do I verify Resend webhooks correctly?

Accepted Answer

The skill provides patterns for using the raw request body with resend.webhooks.verify(). It is critical not to use JSON-parsed bodies, as this breaks the cryptographic signature verification.

Question 3

Why do I need to await render() in React Email?

Accepted Answer

In React Email 5.0+, the render function is asynchronous and returns a Promise; failing to await it results in the string '[object Promise]' being sent as the email body instead of the rendered HTML.

Question 4

How does this skill help with email compliance?

Accepted Answer

It provides implementation patterns for including mandatory unsubscribe links in non-transactional emails and checking user preference schemas, ensuring compliance with CAN-SPAM regulations.

Question 5

Does this skill support bulk email sending?

Accepted Answer

Yes, it includes patterns for the Resend Batch API (resend.batch.send()), which allows you to send up to 100 emails in a single request while rendering templates in parallel.
