CLUSTER CLIENT-EMAIL-MANAGES · 37 ENTRIES · EARLIEST ENTRY 2010-05-08
Email clients with PIM features
This cluster comprises desktop and mobile email clients that often integrate calendar, contacts, and news feeds, ranging from simple Gmail clients to full personal information managers. Dated entries span from May 2010 to July 2026 but are sparse, with the majority of dated entries appearing after 2020 and a slight grouping in 2023 and mid-2026. Traction leaders among members are thunderbird-esr140-bin, WEB.DE - Mail, Cloud & News, and Thunderbird, though all report zero stars.
Entry timeline
ENTRY TIMELINE
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.
