This guide explains how the Jellyfish anti-spam system learns when you mark emails as spam in your Spacemail Webmail. It may help you better understand how the process works in the background so you can manage your email flow effectively.
To mark an email as spam in Spacemail webmail, click on the selected email and then click the ‘Mark as spam’ button (the crossed-out symbol in the toolbar above the email header). That’s it!
Three things happen when you mark an email as spam in your Spacemail account:
The email is moved to the Spam folder
The email is immediately moved to your spam folder to keep it separate from your legitimate emails in the Inbox.
The sender of the email is blocked
The system learns that emails from this sender (mailbox) are unwanted and ensures all subsequent emails from the same sender are delivered to the Spam folder.
Jellyfish filtration learning
The spam filtering system learns from this action and analyses the spam email to identify similar emails in the future. Later, such emails may be automatically filtered into the Spam folder for your particular mailbox.
If you reply to any email that was marked as spam, all subsequent emails are sent to the Inbox and not the Spam folder. The same applies to all senders and emails that ended up in the Spam mailbox but are legitimate, and the user marks them as non-spam (ham).
NOTE: We recommend that you use the 'Mark as spam' button in Spacemail webmail only to ensure that the Jellyfish system is trained properly. Clicking the 'Mark as spam' (or similar) button in your email client to mark certain messages as spam doesn't train Jellyfish due to the individual settings of different email clients. However, you can drag and drop messages to the Spam folder in your email client and this will train the Jellyfish system.
