Mautic + MailKite

Mautic is an open-source marketing automation platform. Point its SMTP at MailKite and every campaign email, nurture sequence, and transactional message goes out over your own DKIM-signed domain.

What you need

A verified domain with SPF + DKIM published
Your API key (mk_live_…)
A Mautic instance (self-hosted or cloud)

Configure SMTP

Open Mautic and navigate to Settings → Email Settings. Click New to add a new email transport and select Other as the service type.

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)

Settings → Email Settings

Test it

Create a test email in the Mautic email editor and use the Send test button to verify the connection. Check your MailKite dashboard to confirm the message was relayed.

Troubleshooting

Emails not sending — confirm the email address is on a verified domain.
535 Authentication failed — your password must be your mk_live_… API key, not a separate SMTP password.
Settings not applying — Mautic may cache transport settings. Clear the cache with bin/console cache:clear.
