Hello,
The Woodmart theme does not automatically install or force plugins like Contact Form 7 and Mailchimp on your site.
Go to Plugins > Installed Plugins, find Contact Form 7 and Mailchimp, and click Deactivate before deleting them.
Or you can delete it via the File Manager plugin for FTP:
Open the File Manager plugin, navigate to /wp-content/plugins/, locate the plugin folders (contact-form-7 and mailchimp-for-wp), and delete them manually.
If you have any questions feel free to contact us.
Best Regards,
