## Frequently asked questions

### Should I use the API or the console?

Use the **API** for programmatic sending, automation, and integration into apps. Use the **console** for setup, monitoring, testing, and one-off operations like creating a broadcast.

### How do I get started sending emails?

First, [verify a domain](https://resend.com/domains). Then, either use the [API](https://resend.com/docs/send-email) with your API key or send via the [console](https://resend.com/emails).

### Why are my emails going to spam?

Check domain authentication (DKIM/SPF/DMARC), warm up new domains gradually, avoid spammy content, and monitor suppression lists. See deliverability best practices in the guide skill.

### Can I manage contacts via code?

Yes—use the Contacts API (`resend-contacts` skill) to create, update, segment, and sync contacts programmatically.

### How do I debug a failed email send?

Check API response errors, review [logs](https://resend.com/logs), verify domain status, and consult troubleshooting guides for 403 errors, suppressions, or DNS issues.
