# Migrate from Resend

## What changes

| Resend | Envimaily |
|--------|-----------|
| `https://api.resend.com` | `https://api.envimaily.com` |
| Resend key | `em_…` key |
| `POST /emails` | `POST /emails` or `POST /v1/emails` |

## Checklist

1. Create a developer account and key
2. Swap the base URL
3. Map `from` to a verified domain (or test sender)
4. Re-point webhooks to the new endpoints
5. Adjust quota alerts (1,000/mo on free)

Payload fields `from`, `to`, `subject`, `html`, `text`, `reply_to`, `cc`, `bcc`, `tags`, `headers`, `attachments` follow a familiar shape.
