We’d never suggest you to use a product we wouldn’t use ourselves. That's what keeps over 1300 people across 21 countries, and 3 continents truly connected.

We support the basic e-mail protocols that you expect. SMTP, IMAP, POP3. We support mail forwarding (aka aliasing), and plus addressing. We offer Crossbox, Rainloop, and Roundcube for your choice in webmail client.

We’ve mostly taken IP reputation off of the table by using a high reputation pool of IP addresses. If an e-mail fails delivery due to IP reputation, we send again, and again, until we get it right. It’s not your problem and we know that.

Frequently Aksed Questions

What is SpamExperts?

SpamExperts offers professional email security solutions such as incoming and outgoing email filtering as well as email archiving solutions. They're one of the most precise spam filtering solutions in the market. With the use of multiple filtering technologies such as advanced IP-reputation systems, a large number of message content classifiers manage to deliver nearly 100% filtering accuracy.

What's the difference between SpamExperts and SpamAssassin?

SpamExperts offers way more accurate email-filtering, it's using multiple technologies to decide if something should be marked as spam or not, where SpamAssassin, in general, are simpler and uses simpler methods to detect possible spam. SpamAssassin is also directly installed on your server and this can consume a lot of server resources which is not the case with SpamExperts and more importantly it isn't updated in real-time like SpamExperts.

What technologies do SpamExperts use and how does it rate spam?

SpamExperts uses a lot of different technologies to decide whether a specific email should be seen as spam or not.There are a few stages how it performs filtering: pre-data, post-data and a stage in between these two.
The pre-data stage includes Connection rate limiting, IP Blacklist checking, destination domain verification, SMTP protocol compliance, sender address inspection, recipient validation checks, whitelist/blacklist of sender and/or recipients, recipient connection rate limit, SPF checks, content reputation feeds, bounce address tag validation as well as simple private signatures.
On the post-data stage, this includes validation of DKIM and DMARC, rules defined by a specific user, virus scanning, DNS and URI reputation checks, fingerprinting, statistical information about senders and heuristics defined by SpamExperts.
In between these two stages, there's also a direct feed looking at general IP reputation, if the sending IP is known for spending spam, and their sending history.
With most or all these metrics - the software will calculate a combined score - and depending on this score it will either accept the email or mark it as spam and thus putting it in the quarantine.
Some of the pre-data checks will result in dropping the emails before even reaching the post-data stage, this only happens if the sending server is poorly configured or being a part of one or more blacklists.

Why does most of my incoming email end in spam?

SpamExperts operate with a very high accuracy, this ensures that only legitimate emails go through but at the same time that the filter doesn't actually block legitimate emails unless something on the sending server isn't configured as it should.
In case most of your incoming email goes to spam are often due to if you're redirecting other email accounts outside your domain or hosting account towards your domain. This on a lot of mail servers rewrites the sender, which as a result will cause a lot of the filtering technologies to see the email as spam, most likely due to invalid SPF or DMARC records.

How perfect is SpamExperts in identifying spam?

SpamExperts can prevent 99% of the spam emails addressed to your domain from reaching your inbox. The tests done by our team proved it to be very effective and that is all without making any changes to the default settings. Although there is no spam detection solution that works 100% perfectly, when this happens, you can flag such messages as spam so that SpamExperts marks them as a spam in future.

Do I get a control panel that I can access?

Yes. If you are a domain administrator, you can set up control panel access for users, or users can set it up themselves. Guidelines to access the control panel are included in the email which individual email users receive from SpamExperts when the first spam message is marked.

Do I need to adjust the settings in SpamExperts?

No, you don't. We have tested the default SpamExperts settings and we found it to be amazingly efficient. If you still want to make the changes in settings that fit in your requirement, you have that ability.

For how long the spam messages are quarantined?

or 28 days. You can retrieve messages any time through the SpamExperts control panel.

Do I have to pay for each individual email address that I want to protect?

No, when we activate SpamExperts for your domain, every email address on your domain is protected from spam.
