TypeConversational email

Spike is an email application for Windows, MacOS, iOS, Android and the web, which enables users to view email in a chat-like, conversational format, with additional features built-in.


Founded in 2013[2] by Erez Pilosof and Dvir Ben-Aroya,[3] Spike is a software application that puts existing e-mails into a multimedia messaging, chat-like interface enhanced with video and voice calls. The application was initially named Hop.[4]

In 2019, the developers completed a $5 million funding round including investment from Wix.com and NFX Capital.[2]

In 2021 Spike announced a collaboration with Meta to launch on the Oculus Store and would become one of the first productivity apps to launch in Meta's new virtual world, known as the Metaverse.[5]

Mode of use

The app enables users to organize email into three types of “conversations,” a traditional inbox/sent format, by subject, or by people. Spike users can also make audio and video calls to each other, and other features include a calendar, contact list, and Groups.

Spike is available for Microsoft Windows, MacOS, iOS and Android, and as a web version,[3] and works with Gmail, Outlook, Exchange, iCloud, Yahoo! Mail and IMAP email providers.[6]
