v0

Add email sending with SendDart to a v0 project by asking the chat to wire it up with your API key.

v0 by Vercel is a platform for building sites, tools, apps, and projects via chat. You can add SendDart to a v0 project by asking the chat to add email sending and pointing it at your SendDart API key.

1. Add your SendDart API key

Create a SendDart API key in the dashboard, then ask v0 to add email sending and store the key as an environment variable (e.g. SENDDART_API_KEY). In Node.js/TypeScript projects v0 can install the official senddart SDK (npm install senddart) and call mb.emails.send(...). In other languages or runtimes, sends are plain HTTP POSTs to https://www.senddart.com/api/emails.

Do not share your API key or expose it in the browser or other client-side code. Keep the send on the server side and read the key from an environment variable.

Example prompt

Add email sending with SendDart. When the contact form is submitted, send an
email by POSTing to https://www.senddart.com/api/emails with an Authorization:
Bearer header using SENDDART_API_KEY. Read the key from an environment variable.

2. Add a custom domain

By default you can only send email to your own address. To send to other recipients, add and verify a custom domain, then update the from field in the send code to use an address on that domain (or ask the chat to update it).
