Unfortunately this behavior is notoriously hard to change. Similar to SEO, you can only try to pass on as many positive signals about your content as possible to the email service provider of the recipient. The eventual decision what to do with that content (whether to put it into the primary inbox or spam folder) rests with the service provider.
For you as the sender that means that you want to absolutely nail all aspects of sender reputation and email deliverability. For an overview, I can recommend this email deliverability listicle. Most importantly, make sure you have connected your email sending domain and set up email authentification (SPF, DMARC).
You can find additional resources here. Over time, email service providers should recognize you as a trustworthy sender. The issue could be that in the past, some recipients have already marked your emails as spam or that your emails caused a lot of hard bounces.
Lastly, you could also consider simply mentioning the fact that emails might land in the promotion tab of the inbox if recipients have a hard time finding it. Once they submit the form, along with the thank you message you could display "Thanks for your interest! Please make sure to check your promotions tab or spam folder for our email."
Hope this helps!
PS. HubSpot has an additional product for a dedicated IP address, specifically for these confirmation type emails (transactional). Here you have more control over your sender reputation.
