Sending Emails

Design and send emails with Nitrosend

Nitrosend supports two ways to send emails: campaigns for bulk sends to a list, and transactional messages for one-off sends triggered by your app.

Campaigns

Campaigns let you send an email to a contact list or segment. Create one from the dashboard:

Go to Campaigns > New Campaign
Choose a template or start from scratch
Select your audience (a contact list or segment)
Preview, test, and send

Transactional messages

For receipts, password resets, and other triggered emails, use the API:

curl -X POST https://api.nitrosend.com/v1/my/messages \
  -H "Authorization: Bearer nskey_live_..." \
  -H "Content-Type: application/json" \
  -d '{
    "to": "user@example.com",
    "subject": "Your receipt",
    "html": "<h1>Thanks for your purchase</h1>"
  }'

Email editor

The drag-and-drop editor lets you build responsive emails visually. Your brand theme (colors, fonts, logo) is applied automatically. All emails are rendered as MJML under the hood for maximum inbox compatibility.
