Hi, your plugin is conflicting with the CF7 pre tag I can’t use the pre-tag on CF7 output the space won’t be reserved when your plugin is activated.

you can test this on your test site by using CF7 and your plugin on the CF7 setting email use HTML and add a pre-tag with [CF7-shortcode-value]

You can test it here on my staging
