Ghost + MailKite

Ghost is a modern publishing platform. Point its SMTP at MailKite and every newsletter, member notification, and staff invite goes out over your own DKIM-signed domain.

What you need

A verified domain with SPF + DKIM published
Your API key (mk_live_…)
Ghost (self-hosted or Ghost(Pro))

Configure SMTP

Edit your Ghost configuration file (config.production.json or config.*.json) and set the mail transport to SMTP with MailKite credentials.

SMTP Host	`smtp.mailkite.dev`
SMTP Port	`587`
Encryption	TLS (STARTTLS)
Username	`mailkite`
Password	Your API key (`mk_live_…`)
From Address	`hello@yourdomain.com` (on a verified domain)

config.production.json

// config.production.json

{
  "mail": {
    "transport": "SMTP",
    "options": {
      "service": "Custom",
      "host": "smtp.mailkite.dev",
      "port": 587,
      "auth": {
        "user": "mailkite",
        "pass": "mk_live_..."
      }
    }
  },
  "from": "hello@yourdomain.com"
}

Test it

Invite a new staff member or trigger a newsletter test from the Ghost admin panel. Check your MailKite dashboard to confirm the message was relayed.

Troubleshooting

Emails not sending — confirm the from address is on a verified domain.
535 Authentication failed — your password must be your mk_live_… API key, not a separate SMTP password.
Ghost(Pro) users — you cannot edit the config file directly. Contact Ghost(Pro) support to update your mail settings.
Self-hosted — restart Ghost after editing config.production.json for changes to take effect.
