CLUSTER EMAIL-CLIENT-POWERED · 25 ENTRIES · EARLIEST ENTRY 2017-10-18

AI-powered email clients

This cluster comprises 21 AI-powered email clients and productivity tools, including email verification services, infrastructure for AI agents, and cross-platform apps. The dated history before the index start shows 13 individual entries spread irregularly from 2015-12 to 2026-07, a slow and sporadic pattern rather than a concentrated rush. Traction leaders by activity signal are flaremail-grok-plugin (0 stars), nebula- (1 star), and Email-Agent-Webhook (1 star).

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
