Something about what it is.

Spam is all bad

Spam is the abuse of electronic messaging systems (including most broadcast mediums and digital delivery systems) to send unsolicited bulk messages indiscriminately. Spam, or unsolicited mail, is infuriating. It abuses a service, floods your email account with illegitimate mail, steals your resources and generally wastes your time and money.


Spam mutates every second of every minute, every day. You may already have anti spam software installed in your mail server, or expensive hardware that installs updates daily into your mail server. Nowadays, this software and hardware works on "signature", which requires updating continually. Initially it filters spam with up to 50-80% accuracy, but as time goes by, its performance will degrade exponentially as spam mutates every minute.

Why Hydra?

Hydra is a dynamic, ever-evolving system that captures 99.99% of all spam without affecting the flow of legitimate email. It uses a proprietary, sophisticated algorithm that ensures it keeps up with the constant, minute-by-minute evolution of spam and keeps your mail servers protected from it. Implementing our service is fast and easy, requiring no hardware, installation or ongoing maintenance from your end.

Hydra is based on our proprietary holistic algorithm running on a cluster of super computers. Hydra is always learning and adapting itself to stay ahead of the threats.


We are running a tight-ship, our team kept very strict rules and intelligent algorithms in Hydra. No Whitelisting, just to name a few. That alone has worked wonders for so many years.

On top of that, we have marvelous 'management', 'statistics' and 'reporting' tools that will put your mind at ease.

Frequently Asked Questions

What do I benefit from getting this service?

Everyone nowadays spends at least 30 minutes of their time clearing junk mails for a whole day. Risking the machine and company with infections and downtime. With this service, you will get higher productivity for your business to do its best (not clearing junk).

Is productivity so important?

It's the thing every company overlooks in businesses. Simple illustration: 30 mins a day, 10 employees, that's 5 man hours a day. With $20/hour rate, that's $100 loss a day, $2K loss per month, $24K loss per year.

I am a one-man-show in my company

The smaller the company, the stronger the repercussion of losing every dollar, the more relevant our service is. Even as a single person, losing 30 minutes a day on rubbish collection times your salary hourly rate, is it worth a dollar? Our service rate is about $1 / day.

Why should I care about non-existence email addresses?

When spammer sends to non existing email addresses, conventionally, your mail server will bounce it back to whatever sender the spammer uses. Bouncing the spam mails is actually helping spammer to distribute their spam on the expense and reputation of your mail server.

What happens to spam mails caught by Hydra?

Because we don't bounce spam mails to stop the spamming vicious cycle, all spams are sent to oblivion, this way our fleets are always in good reputation.

Other service providers offer antispam at a lower cost.

The classic question is always: does it work? Trial ours, then you decide for yourself. All our clients are satisfied clients, All of Them (zero spam in mailbox, false positive is negligible). Quality comes with a price.

Why don't you have different tier of pricing (1, 5, 100 users)?

Our system goes by email address, not email account. Even though you only have boss@yourdomain.com created in your system, you normally have sales, info aliases too and so on, which are forwarded to boss account, that's considered multi addresses. And also spammer sends to random email addresses e.g. boss1@yourdomain.com, a1b2c3@yourdomain.com, we are taking care of those too. No company has purely just one working email address.
Secondly, imagine spammer sends 100K spams to your domain with random email addresses, we have to take care of that too. Otherwise, if we release the 99.9K spams through, our servers will be considered spammer by recipient servers. Not good for anyone. Please be aware that the spams belong to yourdomain.com, hence the domain owner has to be responsible with the problem.
Real world analogy: you receive many letters in your mailbox, and some of them are marketing junks. Do you say that you don't want to pay for rubbish fee for the letters that you don't want or not for you? No matter what, you still have to pay for the rubbish you are throwing away.
