How it sells itself

InboxShield protects your contact form from unwanted messages, fake inquiries, and repeated promotional submissions. You can review message activity, adjust protection settings, manage keyword categories, and keep real customer inquiries easier to notice.

You can set rules to prevent certain email domains and name patterns from being able to create accounts or checkout. This helps you prevent emails from getting passed to platforms like Klaviyo that may charge you extra for users. We help you decrease fake account bloat and prevent malicious, fraudulent and fake emails from creating orders so you have less to deal with later on.

Key points
  • Protect your contact form from unwanted messages
  • Review blocked and allowed messages in one dashboard
  • Adjust protection levels to control message filtering
  • Customize keyword filters to match your business needs
  • Set custom domains for emails you want to block.
  • Prevent malicious, fake or bot emails from checking out.
  • Set custom text/number patterns for email prefixes to block like john.doe
