[suggestion] improve mail reply flow: keep all responses in a single email thread

[vaclisinc]

Description

Currently, each reply from the backend creates a new email. This results in a long list of emails for a single session, which clutters the user's inbox and makes the experience confusing.

Ideally, the entire session should stay within the same email thread.

Suggestion

We can approach this in two phases:

Phase 1 (Near-term)

• After receiving a user's reply, quickly send an acknowledgment email to confirm that the message was received.
• This helps reduce uncertainty for the user and addresses a pain point that came up during real testing with friends.

Phase 2 (Long-term)

• Keep the entire conversation within a single email thread (same Message-ID / In-Reply-To / References headers).
• This makes the whole experience more natural and easier to track, especially in modern email clients.

Benefit

• Cleaner and more intuitive email experience
• Reduces inbox clutter
• Improves user confidence that their message has been received and processed

I may help prototype or draft a plan for this in the future — stay tuned.

Great UX improvement! This would make email interactions much cleaner.

Key points to consider:

• Ensure RFC-compliant threading headers (In-Reply-To, References)
• Add config option to disable for users who prefer current behavior
• Watch for email loops and rate limiting

Looking forward to seeing this implemented!
