📧 Email Spam Filters

Create custom Email filters to block unwanted emails by sender, domain, keywords, or size.

What Are Spam Filters?​

Filters automatically delete, block, or move emails that match your rules.

How they work:

  • Email arrives matching your filter rule
  • Automatically gets deleted or moved to spam
  • Never reaches your inbox
  • Saves you from unwanted mail

Filter Strategies​

Strategy 1: Aggressive Blocking​

Block everything suspicious:

  • Block certain domains permanently
  • Block keywords known to be spam
  • Use "Drop Email" action
  • Regularly review for legit emails

Risk: May miss legitimate email

Strategy 2: Safe Filtering​

Keep emails but organize:

  • Use "Send to spambox" instead of drop
  • Reviews spam folder regularly
  • Move legitimate emails to inbox
  • Less risk of losing important email

Benefit: Can recover if filter too aggressive

Strategy 3: Smart Keywords​

Block only specific phrases:

  • "Free money"
  • "Claim prize"
  • "Urgent action required"
  • "Verify account"

Result: Blocks common spam while safe emails pass through

Combining with Whitelist​

Best practice:

  1. Set up whitelist (important senders)
  2. Then set up filters (block unwanted)
  3. Important emails never caught by filters

See Spam Filters - Combining with Whitelist for how to whitelist.

Tips & Best Practices​

Do:

  • Start with "Send to spambox" (safer)
  • Test filters with sample emails
  • Review spam folder occasionally
  • Use specific rules (not too broad)
  • Document what filters do

Don't:

  • Block entire domains without checking
  • Use "Drop Email" for all filters
  • Create conflicting filters
  • Forget to disable before testing

Troubleshooting​

Legitimate Email Getting Blocked​

Check:

  1. Review filter rules
  2. Is there a matching filter?
  3. Check spam folder (can recover)

Fix:

  1. Delete or disable the filter
  2. Move Email from spam to inbox
  3. Whitelist the sender if important

Filter Not Working​

Check:

  1. Is the filter still in list?
  2. Is it disabled?
  3. Does the rule match exactly?

Test:

  1. Send test Email matching filter
  2. Check if it gets blocked/moved
  3. Verify action is correct

Too Many False Positives​

Solution:

  1. Change action from "Drop" to "Send to spambox"
  2. Make rules more specific (less broad)
  3. Use exact phrases instead of single words
