Cock.li vs Mailo

Cock.li is a public email host from Cock.li, founded in 2013, offering email accounts and webmail through the web, Android, and iOS. Its services are free, with the Free plan listed at free. Mail access includes IMAP and POP at mail.cock.li, while XMPP is listed at xmpp.cock.li. Registration does not require personally identifiable information. New accounts cannot send mail until the user completes a browser proof-of-work challenge that uses a few minutes of CPU time. Cock-mail is described as an open-source, client-side webmail client connecting directly to the IMAP server over websockets, but its 0.0.1 alpha release lacks major features including SMTP. The privacy policy says registration details, stored mail, XMPP data, and 48–72 hours of IMAP and SMTP logs may be retained. Email is automatically scanned for spam. Account information is encrypted server-side, but mail may travel without encryption when TLS is unavailable or not attempted.

Mailo is an email service available on the web and through Android and iOS apps, with calendar, address book, cloud and sharing services. Its free plan includes 1 GB of email storage, 500 MB for documents and photos, five aliases, advertising banners, and IMAP4 and EAS access.

Premium also removes webmail advertising, supports attachments up to 50 MB and provides POP3 or IMAP4 access. It includes a lifetime email address, and the offer can be activated for one to five years. Mailo says it stores data in France, does not use or sell it, and does not read messages; listed features also include end-to-end encryption and custom domains.
