What’s a secret sauce of SaaS marketing?

Create a community of individuals an truly care about their needs

I think it's community and social media? We do PH for the same reason. Twitter seems to have a more universal personality. Build in public and make a fan...?

Not a secret, but email. Email is the channel to build a relationship with your user. Build awareness, likability and trust by communicating with your user via email.

Communities like PH, discord and many others.
