What Spamdrain is

Spamdrain is a web-based anti-spam service that filters incoming email so junk mail, spam, viruses, and phishing attempts do not clutter your inbox. It is designed for people who want to keep important mail visible while automatically removing messages they do not want to see.

The product connects to your existing email account and checks new messages as they arrive. You can review blocked mail, allow newsletters you want to keep, and report unwanted messages so the filter learns your preferences over time. The site says it works across major devices and email environments, including Android, iPhone, Mac, PC, Office 365, Yahoo, and Google Workspace/G Suite.

Core features

Incoming mail filtering

Spamdrain scans each incoming email and removes spam, junk mail, viruses, and phishing attempts before they reach your inbox.

User feedback learning

The service learns from your choices when you mark blocked mail as allowed or report valid messages as spam, which helps refine future filtering.

Blocked message review

Blocked mail can be reviewed in the app or web app, so you can recover legitimate newsletters or confirm unwanted senders.

Reports and review prompts

Spamdrain sends reports about blocked junk mail and may ask you to review messages that look suspicious but are not fully confirmed.

Broad email compatibility

The service works across devices and operating systems, with site references to Android, iPhone, Mac, PC, Office 365, Yahoo, and Google Workspace/G Suite.

Secure account connection

For account access, Spamdrain uses the most secure method available for the provider, including OAuth 2 when supported and app-specific passwords for some providers such as iCloud.

Keep a personal inbox clear
Connect a personal mailbox and let Spamdrain automatically remove junk mail, spam, and phishing attempts so your primary inbox stays focused on messages you want to read.
