Edinum is a Russian business brand offering an integrated workspace for companies, combining email, calendars, file storage, document editing, team chat, video meetings, and other collaboration tools in one service. Organizations use their own domain for employee email, with setup assistance for DKIM, SPF, and DMARC, plus anti-spam protection. The platform includes eleven modules, such as employee directories, shared boards, notes, forms, a knowledge base, and search across messages, files, and events.

Edinum charges 384 rubles per employee per month on a single plan, which includes all modules, pooled storage of 50 GB per employee, open access protocols, backups, and support from engineers. Data is hosted in Russia, and customers can export their information at any time. The service supports migration from Yandex 360, VK WorkSpace, and other IMAP-compatible services, including help transferring mail, calendars, and contacts. Edinum is made by Signal LLC, based in Lipetsk, and offers a live demo without registration or a payment card.
