If there’s something we can criticize about eM Client, it’s the lack of polish that becomes apparent after you use the email client for a while. If you own an older version of eM Client, you can purchase an upgrade license instead of buying the Pro version again. To unlock all features eM Client has to offer, you have to purchase the Pro edition for $49.95. The free edition is unfortunately very limited because it can’t be used for commercial purposes or display emails from more than two email accounts at once. In addition to PGP encryption, eM Client can also offer live email backups, automatic avatar downloading, improved table editor, basic image editing, and auto-replies for Gmail, among other features.ĮM Client is available in two different editions. Recently, the developers of eM Client added support for PGP encryption, allowing users to create and import their PGP keys to send encrypted and signed email messages.
