Why do my signature links point to htmlsig.com first?
Links in your email signature route through htmlsig.com before redirecting to your specified destination. This lets us count clicks and show you that data on your dashboard.
How do I turn off link tracking?
Open the signature in the editor.
Go to the Extra tab.
Turn off the first option, which disables link tracking for that signature.
Important: after changing this setting, you'll need to reinstall the signature for the change to take effect.
