Sentry + MailKite

Sentry is the leading error tracking platform. Point its SMTP at MailKite and every error alert, invite, and report goes out over your own DKIM-signed domain.

What you need

A verified domain with SPF + DKIM published
Your API key (mk_live_…)
Sentry self-hosted or Sentry SaaS with custom SMTP support

Configure SMTP

For self-hosted Sentry, edit sentry.conf.py and add the email configuration. For Sentry SaaS, configure SMTP under your organization settings if your plan supports it.

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

sentry.conf.py

# sentry.conf.py (self-hosted)

SENTRY_EMAIL_HOST = 'smtp.mailkite.dev'
SENTRY_EMAIL_PORT = 587
SENTRY_EMAIL_USER = 'mailkite'
SENTRY_EMAIL_PASSWORD = 'mk_live_...'
SENTRY_EMAIL_USE_TLS = True
SENTRY_SERVER_EMAIL = 'sentry@yourdomain.com'
SENTRY_EMAIL_SUBJECT_PREFIX = '[Sentry] '

Test it

Trigger an error in your application or invite a new member to your Sentry organization to verify email delivery through MailKite.

Troubleshooting

Emails not sending — confirm the SENTRY_SERVER_EMAIL is on a verified domain.
535 Authentication failed — your password must be your mk_live_… API key, not a separate SMTP password.
Self-hosted — restart Sentry containers after editing sentry.conf.py: docker-compose restart.
Sentry SaaS — custom SMTP may require a Business plan. Check your Sentry plan's feature set.
