Message Filter for Contact Form 7 is a WordPress plugin designed to combat spam messages received through contact forms. This free tool allows users to filter submissions based on restricted words or the email addresses of submitters, making it a viable solution for those overwhelmed by spam. Currently, it supports Contact Form 7 and WPForms, with plans for future compatibility with other contact form plugins.

In addition to its basic filtering capabilities, the plugin offers a pro version that includes features like unlimited word and email filtering, monthly spam reports, and customizable blacklist/whitelist options. Users can also upload CSV files containing spam words or emails and create their own custom filters. The plugin prioritizes privacy by limiting data collection to blocked messages and added spam words.
