CLUSTER ACCOUNTS-CLIENT-EMAIL-2 · 17 ENTRIES · EARLIEST ENTRY 2013-09-12

Privacy-focused multi-account email clients

This cluster consists of privacy-focused email clients that connect multiple or unlimited IMAP accounts into a unified inbox, with encryption (PGP/OpenPGP), notifications, offline support, and local search. Its dated history is a long, sparse tail: 14 single-entry months spread from 2013-09 to 2026-06, with no month recording more than one entry. On traction, Gridlink Mail, Emma Email, and Infomaniak Mail lead by activity signal, each showing 0 stars.

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.
