What Seznam Email is
Seznam Email is a mailbox service available at email.seznam.cz, through the web and Android and iOS apps. Its free plan costs nothing and provides unlimited mailbox capacity, antivirus filtering and antispam protection. The inbox is ad-free, but custom domains are not supported. Email.cz apps can hold any number of mailboxes and let you switch between them. Messages can be organized into folders offline, with those folders available on phones and computers. You can select multiple messages to move or archive, delete unwanted mail with a swipe, and get address suggestions after typing three characters. Older messages are searchable, and the iOS app follows the device’s dark or light setting. Offline-composed messages send when internet access returns. Folder deletion can be scheduled for 30 days, 90 days, one year or three years, while trash, spam and bulk-mail folders clear automatically after 30 or 90 days. Seznam Email was founded in 1998 and is headquartered in Prague, Czech Republic.
