Organizing your inbox

You can use Filters & Rules to keep your inbox organized. The Settings → Filters & Rules screen is organized into three sections: Blocked Senders, Spam Protection, and Rules.

Blocked senders

If you receive unwanted messages from the same senders, you can block them. This means that mail sent from this sender will automatically be moved to your Trash folder, so it won’t appear in your Inbox anymore. Senders in your Contacts cannot be blocked.

Block sender from a message

When viewing a message, use the More button at the top right hand side of the email message, then click Block [sender].

The person who sent this message will now be added to your blocked senders, which can be viewed and edited on your Settings → Filters & Rues screen.

Block sender from Settings

To block senders from your Settings screen, go to Settings → Filters & Rules. Next to Blocked Senders, click on View and edit. On the next screen, you'll see a list of any senders you currently have blocked. If you'd like to add a new sender to this list, type their email address or domain in the appropriate field, and click Block.

Spam protection

Fastmail uses many tools that help catch and stop as much spam as possible. If you're receiving too much spam, you can adjust your spam filtering.

For ease of use, we provide three levels of spam filtering: Basic, Standard, and Aggressive, which adjust how we treat spam. This controls whether spam is moved to the Spam folder, or deleted, and whether mail from known spam hosts is blocked. If you'd like greater control, you can use the Custom settings to refine further.

More detailed information about spam protection can be found on our spam protection help page

Rules

Rules can be used to automatically perform actions on messages that are sent to your mailbox, like moving them into a folder, or forwarding them to another account. Rules are created from our web interface, but they still function even if you use a mail client to read your mail.

A rule has two parts: conditions that a message must have for a rule to take place, and the actions to take when a message matches the condition(s).

When you create a rule, you also have the option to apply it to any messages currently in your mailbox that match the conditions you've set up, so rules can be handy tools to organize your mail in one swoop.

Creating a new rule

There are three ways to create a new rule:

  1. Create a new rule based on the current message
  2. Create a new rule from the Settings → Filters & Rules screen
  3. Create a new rule from a search.

Creating rules from the current message

When viewing a message, use the More button at the top right hand side of the email message, then the Add Rule from Message... option. A popup appears that lets you quickly build a rule based on the sender, recipient, subject, or mailing list ID of the current message.

At the top of the popup, you can set the conditions that the message must meet for the rule to take effect. We automatically fill in some matching conditions, such as the From and To addresses of the message, but you can remove or add conditions as you'd like.

You can then choose what will happen to a message if it meets the rule conditions. If you'd like more rules to run on the message after this rule, tick off the option to Continue to apply other rules. This option can't be ticked off if you're creating a rule to move or delete a message, though.

If you'd like, you can enter a name for the rule in the Name section, so you can write yourself a note about the rule's purpose.

Once the rule looks good, click Save.

Once the rule is created and saved, you can find the rule in the Settings → Filters & Rules screen, where it can be edited. Rules are applied from top to bottom, so if you'd like to reorder your rules so that certain ones run first, drag and drop your rules.

Creating rules in the Settings screen

To edit rules or create a new rule from scratch, open the Settings → Filters & Rules screen, and click on Create Rule. On the following screen, you can input conditions for your rule, such as the From or To address, or the subject of the message. If you want to add multiple conditions, click the Add Condition button.

If you're building a rule with more complex needs, click Switch to Sieve constructor. Rules can't be previewed when using this option, and this option is recommended for more advanced users.

Once you've added the conditions you need, click Continue. You'll be brought to a preview screen in your mailbox. If any messsages in your mailbox match your rule conditions, you'll see them here.

If everything looks OK, then click Create Rule. On the popup that appears, you can choose what will happen to a message if it meets the rule conditions, and whether the rule should apply to current matching messages now, to new incoming messages, or both.

If you'd like more rules to run on the message after this rule, tick off the option to Continue to apply other rules. This option can't be ticked off if you're creating a rule to move or delete a message, though.

If you'd like, you can enter a name for the rule in the Name section, so you can write yourself a note about the rule's purpose.

Once the rule looks good, click Save. You'll be brought back to your Settings → Filters & Rules screen where you can view the rule.

Rule conditions

When you take an action on messages, you create a rule that only applies to messages which match a set of conditions.

Conditions can be combined within a single rule. Either:

Each condition can examine a different part of a message. For ease, we allow you to set up a rule with some common conditions, such as:

A full list of conditions can be seen when creating a rule.

If you're building a rule with more complex needs, click Switch to Sieve constructor. Rules can't be previewed when using this option, and this option is recommended for more advanced users.

Rule actions

Once the rule condition has been met, the rule action is applied to the message.

The following actions can be taken on a message:
