CLUSTER CONTACTS-EMAIL-HOSTED · 20 ENTRIES · EARLIEST ENTRY 2026-09-01

Self-hosted email tools

This cluster comprises self-hosted email solutions—servers, webmail clients, alias services, and cold-email platforms—that give users control over their inbox infrastructure. The cluster's dated history is too thin to read a shape from; only two members have pre-index source dates, so it predates the index or is largely undated. On traction, mailriz leads with 27 stars, while nexmail and raymail each have 2 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.
