Hi @AlexHW This depends on a few factors, such as your email sending history/score, your domain score, and the email service provider you’re using and the client is viewing the email in. I’m afraid we don’t have much control over this message being displayed, but I think this article overall is helpful in explaining why this message shows. I’d also suggest embedding the Typeform onto your website, if you haven’t already. 

Thank you for the answer

Not a problem, @AlexHW ! Hope it helps a bit.
