To send newsletters and campaigns with OwnMailServer, run Listmonk for your contacts, lists and campaigns, and point its SMTP settings at us: smtp.ownmailserver.com , port 587, STARTTLS, with an API key as the password. Then slow Listmonk down to our 10 messages a second, cap it at your daily warm-up limit, and forward our bounce webhooks to Listmonk. It takes about an hour.

OwnMailServer is a sending service: it delivers email, handles bounces and complaints, warms up your sending and watches your reputation. It doesn't store contact lists or edit campaigns. Listmonk does, and it's free, open source and self-hosted, so your subscriber list stays in your own database.
