“You absolutely can use Substack without sending all your website traffic to a Substack subdomain.”
“Substack provides an embeddable signup form that you can place directly on your website.”
“It works with platforms that support iframes, including:”
“Substack also supports custom domains.”
“Subscriber management, email delivery, paid subscriptions and publishing”
“The limitation: Substack's native embedded form isn't very customizable.”
“The main drawback is that the official form has limited styling options.”
“Substack currently charges a one-time $50 USD fee for connecting a custom domain.”
“One technical limitation: Substack requires a subdomain, such as www.yourbrand.com or newsletter.yourbrand.com, rather than directly hosting the publication on the root domain.”
“Substack's native embed is a signup form, not a complete embedded landing page.”
