How the best antispam service reducing junk mail works

If your UOL Mail inbox is filling up with junk mail, phishing attempts, and unwanted marketing email, Spamdrain adds an extra filtering layer and removes unwanted messages quickly as they arrive.

UOL Mail includes basic spam filtering, but many users still receive newsletters, graymail, and phishing mixed into the inbox. Spamdrain filters the noise and learns quickly from your feedback.

UOL Mail accounts are often checked in the browser at email.uol.com.br and in phone or desktop mail apps. If your mailbox supports IMAP/POP, Spamdrain can monitor the mailbox and remove spam before daily webmail checks.

Why spam still reaches UOL Mail inboxes

Spammers constantly change tactics and often look legitimate. Provider filters must balance false positives, so some junk slips through.

What Customers Are Saying

Thank you! I appreciate the quick and helpful reply. Thanks for Spamdrain. It keeps me from going crazy with junk in my inbox.

I've been using this app for the past 3 weeks only. The product is exceptional in identifying spam and fraudulent emails that my other spam apps couldn't identify because of constant domain name changes!

Works well in removing known spam, and asks about any new mail that it is suspicious of giving you the choice to give it the 'all clear' or condem it to spam for evermore. Recommended to keep the clutter out of your inbox.

This beats all the rest and keeps spam out of my inbox. I've been using them for 3 years now and am very happy!

Excellent SPAM filter, trains quickly when new forms of SPAM appear. Highly recommended.

Best spam blocking app on the market hands down. Money well spent.

I’ve tried several apps that state they will block spam from emails. So far , all have failed until I found Spamdrain. It has blocked 90% of spam so far. If one sneaks through, you just click on it and state it’s spam and it never finds your inbox again.

Wow, what a spectacular improvement! I started with the trial, and it only took a few days to see I don't need to wait before buying the app. I don't understand why my ISP email provider isn't performing this same service for me. Doesn't matter, Spamdrain is doing the job well!

It’s hard to believe that I have finally found an app that actually helps tremendously with spam. My email inbox is cleaner than it has been in years. Very much worth the small amount of cost. You need to try it. Unfortunately everyone has a spam problem now
