Alternatives

Products that do what Open-source email helpdesk does

We've tried systems like OSTicket, OTRS etc, but never found anything to our liking. Most systems were cluttered, slow or too advanced. Brimir is simple but usefull.

Open sourcing my email sending startup▲38
Hi all, I've posted a few times here about Maildown, a startup that I've been trying to validate lately. Due to lack of time to focus on this, I've taken the decision to abandon the project as a startup, but to make it available as an open source solution instead. The (still very basic) github repository is here: https://github.com/chris104957/maildown Maildown now exists as a simple CLI wrapper for Amazon SES which bakes in Markdown and styling support, making it much easier to get transactional mails up and running in any project Thanks for looking, Chris

An open-source email archiver with full-text search capabilities▲9
Hey HN, I’d like to share an open-source project I’ve created. It is an email archiving tool that can back up your whole email system with full-text search capabilities. The project is called Open Archiver, and it is able to archive and index emails from cloud-based email inboxes, including Google Workspace, Microsoft 365, and any IMAP-enabled email inbox. You can connect it to your email provider, and it copies every single incoming and outgoing email into a secure archive that you control (Your local storage or S3-compatible storage).

Maildown – Markdown email campaigns▲92
Hi, The beta program of my new startup, Maildown, is now complete and is now accepting paying customers: https://www.maildown.app As well as a lot of stability enhancements, we've added a new help system, a new CLI (https://github.com/chris104957/mailer-cli) and a REST API. Maildown lets you create transactional and marketing email campaigns using Markdown syntax, so you can generate and send your email content far more quickly than with traditional WYSIWYG editors. Thanks for looking, Chris
