Spam filtering for domains

Spam filtering for domains

EmailConnect provides built-in spam filtering to protect your webhooks from unwanted emails and reduce unnecessary processing costs.

How spam filtering works

When enabled, EmailConnect uses advanced spam detection algorithms to:

  • Analyze email headers and content
  • Check sender reputation
  • Identify common spam patterns
  • Block emails before they trigger webhooks

Enabling spam filtering

When creating a new domain

  1. Click "Add domain" in your dashboard
  2. Enter your domain name
  3. Toggle "Enable spam filtering" to ON
  4. Complete the domain setup

For existing domains

  1. Go to your domain settings
  2. Find the "Spam filtering" section
  3. Toggle the setting to enable/disable
  4. Changes take effect immediately

What happens to spam emails?

When spam filtering is enabled:

  • Suspected spam emails are blocked at the SMTP level
  • No webhook is triggered
  • No credits are consumed
  • The sender receives a standard rejection message

Spam filter sensitivity

EmailConnect uses a balanced approach that:

  • Blocks obvious spam (Nigerian princes, fake pharmacies, etc.)
  • Allows legitimate automated emails (receipts, notifications)
  • Learns from global spam patterns
  • Minimizes false positives

Best practices

When to enable spam filtering

Recommended for:

  • Public-facing email addresses (support@, info@, contact@)
  • Domains receiving high volumes of email
  • Cost-sensitive applications
  • Production environments

Consider disabling for:

  • Internal automation addresses
  • Testing environments
  • When you need to receive all emails regardless of content

Monitoring spam filtering

Check your domain statistics to see:

  • Total emails received
  • Emails blocked by spam filter
  • Spam block percentage

This helps you understand if legitimate emails might be blocked.

Common scenarios

Customer support emails

Enable spam filtering for support@ addresses to avoid:

  • SEO spam
  • Link building requests
  • Automated bot submissions

Order processing

For orders@ or invoices@ addresses, you might want to:

  • Disable spam filtering initially
  • Monitor incoming emails
  • Enable filtering once you understand traffic patterns

Public contact forms

If your contact form sends to an EmailConnect address:

  • Enable spam filtering
  • Add form validation on your website
  • Consider CAPTCHA for additional protection

Troubleshooting

Legitimate emails being blocked

If you suspect false positives:

  1. Temporarily disable spam filtering
  2. Ask the sender to retry
  3. Check if the email arrives
  4. Report false positives to support

Too much spam getting through

If spam filtering isn't catching enough:

  • Ensure it's enabled for the domain
  • Check that emails are arriving at the correct aliases
  • Contact support for filter adjustments

Advanced configuration

Whitelisting (coming soon)

Future updates will allow:

  • Whitelisting specific sender domains
  • Custom spam rules
  • Regex-based filtering

API-based filtering

Use the EmailConnect API to:

  • Check spam filter status
  • Enable/disable per domain
  • View spam statistics

Faq

Tips for reducing spam

Beyond EmailConnect's filtering:

  1. Use obscured email addresses on websites
  2. Implement form validation
  3. Use subdomain strategies for public addresses
  4. Rotate aliases periodically for high-spam addresses

Spam filtering helps you focus on legitimate emails while keeping your webhook endpoints clean and your costs predictable.
