The time we spend managing spam request from users have reduce drastically. Moving to Zerospam as free us a lot of time to focus on other problematic and totally rely on their system to take over our mail protection. As of today, we had 0 issues and everyone is satisfied with the results. Other cities were targets of email attacks recently, we were also a target, but the difference is that nothing went thru the Zerospam engine, so we were not even aware there was an attack. This proves that we can fully trust Zerospam.

Reliable, performant, trustworthy, excellent customer service.

Nothing, for now everything is working like a charm.

Practically no more spams. An additional view on our mail flow. A buffer that will keep the incoming mail waiting while we work on the mail server.

Easy to use tools for control over white/black lists, reports, and logs to diagnose why an email does not come through. Very good control over spam/virus/phishing, they have practically disappeared from our email flow. The occasional one gets through sometimes, but it's not long before the system notices and begins blocking it.

As for false-positives, sometimes also, but it's related to the sensitivity of the system which is required, and is not really a nuisance. A tool to see current greylists would be a good tool to speed up diagnosis of mail flow sometimes.

Good blocking engine. Fast setup. Bilingual Service

No way to recover blocked emails. Transfers from other domains are received at random.

Not much to be said here. Zerospam has been such a useful tool for us so far. The 'issue' with reviewing a useful product like Zerospam is that you only notice it when it's not working correctly, and so far, fortunately, I haven't had the chance to experience this. It runs well in the background and simply filters my inboxes for what doesn't belong there.

Easy to set up, easy to use, easy to stay protected!

It just works... and we don't have to worry about individual users releasing quarantined items into the wild.

There are few products on the market that work as advertised. This just happens to be one of them. We've been using it for years now ourselves, and recommending to all of our clients.

I don't have any complaints about their product, support, or the ease of getting the whole solution actively working within minutes.
