Matomo + MailKite

Matomo (formerly Piwik) is an open-source analytics platform. Point its SMTP at MailKite and every report, alert, and user notification goes out over your own DKIM-signed domain.

What you need

A verified domain with SPF + DKIM published
Your API key (mk_live_…)
A Matomo installation

Configure SMTP

Open Matomo and go to Settings → General Settings → Mail server settings. Select SMTP as the mail transport and enter the 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)

Settings → General Settings → Mail server

# Settings → General Settings → Mail server settings

Mail transport:         SMTP
SMTP server address:    smtp.mailkite.dev
SMTP port:              587
SMTP username:          mailkite
SMTP password:          mk_live_...
SMTP encryption:        TLS
Email from:             hello@yourdomain.com

Test it

Trigger a scheduled report or user notification from the Matomo admin panel. Check your MailKite dashboard to confirm the message was relayed successfully.

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.
Wrong transport — ensure Mail transport is set to SMTP, not PHP mail().
