A buildable angle
The opening
Email channel separation: transactional vs bulk vs marketing with isolated queues.
How to validate it
- Read the whole thread and note the recurring scenarios — repetition is the density of the need.
- Search existing tools around "email queue / reliability" and check which single step they actually cover.
- Put up a one-line landing page, share it back to Discourse Meta, and see whether anyone asks about pricing.
