A.3 “System Availability” means the percentage of total time during which the Service is available to Customer, excluding Scheduled Maintenance Window and Emergency Maintenance.

B. Service Credits

B.1 For each of the SLAs described in Section 2, if in any calendar month the SLA is not met and if Customer has fulfilled all of its obligations under the Agreement and the SLA, Customer will be provided with a Service Credit for the month in which the failure to meet the SLA has occurred. The Service Credit will be calculated in accordance with the tables in Section 3.

B.2 “Service Credit” means the percentage of the monthly fees paid or payable for the Service that is awarded to Customer for a validated claim associated with the Service related to breach of the applicable SLA during that month.

Failure to comply with these reporting requirements may forfeit each Customer’s right to receive a remedy in connection with an SLA.

C.3 For all claims subject to validation by Spambrella, Spambrella will use log files, database records, audit logs, and any other information available to validate claims and make a good faith judgment on the applicability of SLAs to said incident. Spambrella shall make information used to validate a SLA claim available for auditing by Channel Partner at Channel Partner’s request.

C.4 In the event that more than one aspect of the Service product is affected by the same root cause, the single SLA applicable to such Service of Customer’s choosing may be claimed and no other claim will be validated or otherwise allowed for that event.

Robust, versatile, and reliable...
The reliability of the service and the level of protection that it provides. My spam levels immediately dropped to near zero.

There are almost no false positives. And I'm easily able to customize the level of protection with whitelists, blacklists, and sensitivity settings. I'm also a big fan of the antivirus and URL scanning features.

Easy to onboard my customers from another spam filtering system. Very fast and haven't had any downtime in the 9 months since I have moved to Spambrella. When I have had to use support, responses where quick. I had to move all my customers from another filtering system with little notice. After I moved my customers I realised how bad the old solution I used was. Contact with Sales and Support always been professional

Allen B., Review via Gartner Capterra

I found spambrella to be easy to set up and has dramatically reduced the number of spam emails hitting our inboxes. It was easy to 'train' the software to release any genuine emails that were caught or add any spam that was not picked up.

Within a couple of weeks of use virtually no spam arrived to our mailboxes. Spam and phishing emails are a growing problem for everyone I'm sure. I now get a very low incidence of spam.

David F., Review via Gartner Capterra

It doesn't require an arcane knowledge to set the Spam filtering up, the guides are straight to the point and support staff are very helpful. Functionality wise, in short: we do not get spammed. Thanks to Spambrella.

Archiving wise, the new solution is easy to use, searches well and fast and is by far the cheapest we could find at the time. Ten year retention rocks!

Verified Reviewer, Review via Gartner Capterra

Used the software for: 2+ years - 5/5 Overall
With an ever overloaded department, and with cybersecurity skills shortage getting worse securing the I.T infrastructure.

Offloading the task of e-mail filtering to Spambrella has dramatically helped in the department's performance. The only drawback in our case is that the service is hosted outside of our territory and thus out of the legal jurisdiction.

John P., Review via Gartner Capterra

The service is great at filtering bad email as well as junk email out while allowing clean email though. I have used a few other options over the years and this is the best I have found. Clients sometimes have trouble configuring their settings to how they want it to be. Or tag emails as approved when they shouldn't and need IT interaction to resolve. Maybe just ease of use or having a more clear way for clients to resolve basics on their own.
