Currently each individual email is summarised and collated together, which can result in duplication. For example, the same news may be mentioned in multiple emails. To improve this, all emails could be summarised together as one, and organised by topic. Each summarised point would link to multiple email sources where needed.
For example:
> Topic: AI News
> Apple AI announcement: Tim Cook expected to tease new AI features at upcoming event, with more details at WWDC. [TLDR ↗] [Tech Buzz ↗] [Superhuman AI ↗]
This would reduce all duplication, and therefore reading time.
