The Search for Email Clients that Use Gmail Thread IDs
As I wrote on MacStories earlier this week, I’ve been testing an agentic workflow in Claude that allows the model to interact with Zapier and connect my Gmail inbox to Todoist. The idea is that every few days, I can take advantage of natural language understanding in a “hybrid automation” setup that scans my inbox for messages I haven’t replied to, understands which ones seem important, and saves them as deep-linked tasks in Todoist. In the article, I explained that those deep links are Superhuman links that reopen a specific conversation directly in the Superhuman app. More specifically, those URL schemes are constructed using the thread identifier of a conversation in Gmail, which Claude can access.
I mentioned Superhuman not because I’m particularly fond of the app, but because it’s one of the few email clients I’ve found that supports deep links based on the Gmail identifier of a message rather than a proprietary one. That discovery led me down a research rabbit hole aimed at discovering how many clients support a similar feature across platforms…and it’s not that many. Which is why I’m publishing this short note: I want to see if there’s anything I’m missing.
