Mailpile is a webmail client with encryption and privacy features built-in. Mailpile is free and open-source software.


Mailpile is an email client with a heavy focus on providing users with encryption and privacy features by default.[6] Mailpile currently supports PGP encryption natively and stores all locally generated files in encrypted form on-disk. Its first publicly tagged release was 0.1.0 in February 2014 and included an HTML5-based interface, an original typeface (also named "Mailpile"), UI feedback of encryption and signatures, a custom search engine, integrated SPAM-filtering support, and translations to around 30 languages.[7] Mailpile released a beta version September 2014.[8]


The project ran a crowdfunding campaign on Indiegogo from August to September 2013, and successfully raised $163,192.[9][10] In the middle of the campaign PayPal froze a large portion of Mailpile's funds but was subsequently released after Mailpile took the issue public on blogs and social media platforms including Twitter.[11][12]
