Creative Engagement Strategies for SaaS Prospecting

Hello all ! I am an AE who works in the SaaS space, and one of my key KPI's is to have meetings booked, and create a pipeline out of them. Somehow, I notice a trend where the same way of engagement with a prospect does not work anymore. Has anyone here tried any creative ways of engaging with your prospects ? It would be great if you can share your ideas or two cents over here. Also, It would be great if ya'll can share some of your opening lines with prospects on Linkedin messaging, and how do you continue the conversation without the prospect going cold ? Earlier, I used to leave long paragraphs on my company and what pain point i'd resolve for them, and this would not get any response. However, now, I have transitioned to a simple, "How are you doing", to initiate, and I seem to be getting some responses, however, the conversation fizzles away. So, mine is a two part question here 🙂
