CLUSTER CUSTOM-DESIGNING-DRAG · 18 ENTRIES · EARLIEST ENTRY 2026-08-13

Email creation and editing tools

This cluster spans web apps and add-ons for composing, editing, and sending emails, including HTML editors, template builders, and tools that convert Markdown or handwriting into email content. The dated history before the index is thin: one entry in September 2013, then isolated entries in February 2022, May and June 2025, and July 2026, with long gaps between them. Traction leaders by activity signal are aqademiq-email-studio, composer, and email-design, though all show 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.
