Using your own domain for push notification collection can help build trust with visitors. When people see your main website name in the browser prompt, they’re more likely to allow notifications because it feels familiar. A subdomain can still work, especially if you're running multiple offers or separating different types of content, but the main domain often performs better in getting sign-ups. Some push services allow you to collect subscribers through their domain, but that can hurt your branding and control. If possible, stick with your main domain so everything looks professional and connected. It also gives you full control over how and where notifications are sent.
