How to send Firebase email through OwnMailServer

OwnMailServer enables email delivery for various platforms. Firebase users can integrate via custom SMTP, the Trigger Email from Firestore extension, or Cloud Functions. For newsletters, Listmonk connects using smtp.ownmailserver.com on port 587 with STARTTLS and API key authentication, requiring rate limiting and bounce webhook forwarding. Laravel integration involves configuring the .env file with SMTP settings and a verified domain. OwnMailServer manages delivery, reputation, and bounces without storing contact lists or editing campaigns.
