What Spamdrain filters on iPhone

Spamdrain works independently of your iPhone device and email app.

  • Junk newsletters and mass email
  • Phishing and scam messages
  • Spoofed emails pretending to be trusted senders
  • Repetitive unwanted senders

Review blocked email anytime and allow messages that were filtered by mistake.

Why spam still appears on iPhone

Most filtering happens at the provider level. While Comcast Xfinity blocks some spam, graymail and evolving spam techniques can still slip through, so an extra layer helps keep your inbox clean.

FAQ

 Will Spamdrain still help if I use Xfinity Connect and Apple Mail on iPhone?

Yes. Outlook downloads the already-filtered mailbox, so junk volume drops there too.

Spamdrain targets phishing and scam messages and removes them quickly from your mailbox.
 What if an important email is blocked?
You can review blocked mail and allow senders with one click.
