Freshdesk + MailKite

Freshdesk is a help desk platform. Use MailKite to receive inbound email as Freshdesk tickets — customer support requests are created automatically.

What you need

A verified domain with SPF + DKIM published
Your API key (mk_live_…)
Freshdesk account with API key

Send email

Use MailKite SMTP for outbound transactional email. Freshdesk handles replies within its ticket system.

smtp-config

SMTP Host: smtp.mailkite.dev
SMTP Port: 587
SMTP Username: mailkite
SMTP Password: mk_live_...
From: hello@yourdomain.com

Receive inbound email (optional)

Point your domain's webhook to this handler. Each inbound email creates a Freshdesk ticket automatically.

handle-inbound.ts

// Receive inbound email → create Freshdesk ticket
const FRESHDESK_API = 'https://yourdomain.freshdesk.com/api/v2';

async function handleInbound(email) {
  const res = await fetch(`${FRESHDESK_API}/tickets`, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      Authorization: `${process.env.FRESHDESK_API_KEY}:X`,
    },
    body: JSON.stringify({
      email: email.from,
      subject: email.subject || 'Inbound email',
      description: email.text,
      type: 'Incident',
      priority: 1,
    }),
  });
  return res.json();
}

Test it

terminal

curl -X POST https://your-worker.example.com/mailkite-inbound \
  -H "Content-Type: application/json" \
  -d '{"from":"user@example.com","to":"support@yourdomain.com","subject":"Bug report","text":"The button doesn\'t work."}'

Troubleshooting

Freshdesk API key is your password with :X appended (e.g. abc123:X).
Ensure the sender email exists as a Freshdesk contact, or enable "auto-create contacts."
Find your API key under Profile Settings → Your API Key.
