Antispam service that keeps junk mail, phishing and viruses out of every inbox
Works with iPhone, Android, Mac, PC, Office 365 and general IMAP/POP accounts, so one filter protects every device that reads the same mailbox.
Every new message is analysed before delivery, and suspicious senders, malicious links and infected attachments are stopped instead of reaching you.
Each time you mark something as spam or confirm it is legitimate, the filter learns your preferences and gets more accurate over time.
Held messages are not lost. You can open your Spamdrain account, inspect what was blocked, and release false positives with a click.
