You should have a contact page on your links page as a reliable way to contact you. Social media platforms come and go or may change their policies that can affect your access. A fan, fellow streamer, or potential sponsor may want to officially contact you. Using a contact form protects your email address from the world wide web and any potential spam submissions.
We recommended using a dedicated email for your streaming that matches your branding. This will keep your streaming life separate from your private life and will be more secure. There are plenty of free email providers out there like gmail so it is not hard to set up.
