CLUSTER EMAIL-CAMPAIGNS-HOSTED · 11 ENTRIES · EARLIEST ENTRY 2026-09-05

Self-hosted email marketing platforms

This cluster consists of open-source or self-hosted email marketing tools that let organizations create, schedule, and send campaigns from their own infrastructure, while managing subscriber lists and handling bounces. The dated history before the index start is too thin to read a shape from—only one dated entry exists, meaning the cluster either predates the index or its members are largely undated. Among the traction leaders, nudgeon-platform shows the highest activity signal with 3 stars, followed by campaigns with 1 star and Ermes with 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.
