How the best antispam service reducing junk mail works

Terra Mail on iPhone can be read in Apple Mail while the Terra webmail remains available. Spamdrain filters at mailbox level when IMAP/POP access is supported.

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
