Resend Email API
Send transactional emails, manage contacts, and domains via Resend's REST API.
Official docs:
https://resend.com/docs/api-reference/introduction
When to Use
Use this skill when you need to:
Send transactional emails (welcome, password reset, notifications)
Send batch emails to multiple recipients
Manage email contacts and audiences
Verify and manage sending domains
Track email delivery status
Prerequisites
Sign up at
https://resend.com
Go to API Keys:
https://resend.com/api-keys
Create a new API key
Set environment variable:
export
RESEND_TOKEN
=
"re_xxxxxxxxx"
Important:
When using
$VAR
in a command that pipes to another command, wrap the command containing
$VAR
in
bash -c '...'
. Due to a Claude Code bug, environment variables are silently cleared when pipes are used directly.
Placeholders:
Values in
{curly-braces}
like
{email-id}
are placeholders. Replace them with actual values when executing.
