How do you market your SaaS? What works?

hi, I wanted to ask how you guys market your SaaS and especially what works well for you.

We tried a few things the last couple of months, paid ads on Meta and Google which are doing okay, Google PMAX campaign is the current winner in our case. LinkedIn outreach is more or less a pain rather than a revenue machine.

Last but not least email outreach which costs us a lot of money lately because of EU regulations we received a lot of warning letters from the recipients' lawyers. People are somehow directly writing to their lawyers if one marketing email is coming in.

How does your marketing strategy look like, how do you get people into your demo calls or into your software?
