Spam filter for your email
We filter.
You decide.
Every email passes our spam filter first. We hold on to suspicious messages. You choose how strict we are and what still gets through.
How it works
Follow an email on its way to your inbox
This is what happens to every email sent to your domain. Next to it is the real dashboard where you manage everything. Go ahead and try it: it uses example data and nothing is saved.

Step 1
An email arrives
Studio Nova sends you a quote. Before it reaches your inbox, the message passes our spam filter first.
New messageHi! As discussed, here is our quote for your new branding. Let us know if you have any questions.

Step 2
We scan for viruses
We check the message and its attachments. Does it contain a virus or an attachment that isn't allowed? Then the message gets a security hold.
This check is always on. Even when you turn spam filtering off.
-
Step 3
Your sender rules count
Is the sender on your allow list? Then the message gets through. On your block list? Then it goes to quarantine. Set this for your whole domain or per email address.
With a wildcard such as *@example.com you cover every sender of a domain at once.
-
Step 4
The message gets a spam score
The more suspicious the message, the higher the score. Is the score above the limit you chose? Then we hold the message.
Choose another level and save your change. See what happens to the quote.

Step 5
Inbox or quarantine
Good mail goes straight to your inbox. Held mail is in quarantine. Is there a good email among it after all? Preview it safely and release it.
Choose ‘Release & allow sender’. Mail from this sender then comes straight through from now on.

Frequently asked questions about the spam filter
Is the spam filter included in my plan?
Yes. The spam filter is included in all our plans with email. It works for every mailbox on your domain and you manage it in your dashboard.
What is a spam score?
Every message gets a score: the more suspicious, the higher. With the sensitivity you choose from which score we hold a message. ‘Very strict’ has the lowest limit, ‘Even less strict’ the highest.
Which level should I choose?
Start with ‘Default’. Still getting too much spam? Choose ‘More strict’. Missing a good email now and then? Choose ‘Less strict’ or put the sender on your allow list.
Is it safe to preview a held message?
Yes. You see a safe text preview. Remote images, links and attachments are not loaded.
What happens when I allow a sender?
We then treat that sender as trusted for spam filtering. Virus and attachment checks still apply.
Why can't I release some messages myself?
Messages with a virus or an attachment that isn't allowed get a security hold. Think it's a mistake? Contact our support team.
Can I turn the spam filter off?
Yes, but more unwanted email may then arrive. Your sender lists are kept and virus and attachment checks always stay on.
