Frequently asked questions
What makes Resend different from SendGrid for AI agents?+
Resend has a simpler API surface, better developer experience, and React Email support. For agents, the simpler API means fewer parameters to manage and less room for error.
Can AI agents send batch emails with Resend?+
Yes. Use the createBatch action to send multiple emails in a single request. This is more efficient than individual sends for notification workflows.
How do I track email delivery from AI agents?+
Use the getEmail action with the email ID returned from sendEmail. Check the status field for delivery, bounce, or complaint events.
