Password reset and verification emails

Transactional auth mail — password resets, email verification, magic links — is a core SuperSend TX use case. Send them with POST /emails (or the npm SDK) from a verified domain.

Recommended flow

Create an API key in the dashboard
Verify your sending domain (Domains)
When your app issues a reset or verify token, call SuperSend TX with the link in html / text
Optionally track delivery via webhooks

Example: password reset

import { SuperSendTX } from 'supersendtx'

const client = new SuperSendTX(process.env.SUPERSENDTX_API_KEY)

export async function sendPasswordResetEmail({
  to,
  resetUrl,
}: {
  to: string
  resetUrl: string
}) {
  return client.emails.send({
    from: 'noreply@yourdomain.com',
    to,
    subject: 'Reset your password',
    html: `<p>Reset your password:</p><p><a href="${resetUrl}">${resetUrl}</a></p><p>If you did not request this, you can ignore this email.</p>`,
    text: `Reset your password: ${resetUrl}\n\nIf you did not request this, you can ignore this email.`,
  })
}

curl:

curl -X POST https://api.supersendtx.com/emails \
  -H "Authorization: Bearer $SUPERSENDTX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "from": "noreply@yourdomain.com",
    "to": "user@example.com",
    "subject": "Reset your password",
    "html": "<p><a href=\"https://yourapp.com/reset?token=…\">Reset password</a></p>"
  }'

Example: email verification

await client.emails.send({
  from: 'noreply@yourdomain.com',
  to: user.email,
  subject: 'Verify your email',
  html: `<p>Confirm your email:</p><p><a href="${verifyUrl}">Verify email</a></p>`,
  text: `Confirm your email: ${verifyUrl}`,
})

Templates

For repeated auth copy, store HTML in Templates and send with template variables instead of inlining markup every time.
