Marketing Funnels - What are you using?

I'm starting to use a Go High Level service called Snipey leads and it has a lot of capabilities for marketing funnels. I know jobber has automations around quotes, jobs etc. Those are great - but what I'm looking for is what are some of your favorite funnels you have set up right now that have been successful in your business? Or do you have a nurture campaign set up you'd be willing to share. 

I'm looking at setting up an IG "comment this" for XX amount off your next job or something but I want it to be valuable. One that I've had set up with Chiirp (but will be switching soon) is following up with their job after 30 then 90 days. Checking in to make sure everything is looking good and seeing if they have any questions on their install.
