CLUSTER EMAIL-WEB-CHECKS · 15 ENTRIES · EARLIEST ENTRY 2026-09-02
Email security and validation tools
This cluster comprises web apps and APIs that audit email security, validate addresses, check breach exposure, and score deliverability. The dated history is too thin to read a shape from—only 0 dated entries exist before the index start, and 5 members have no source date. Traction leaders by activity signal are toolbox, exposurewatch, and breach-beacon, each with 0 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.
