What to include in a B2B Funnel ?

Hi Hunters, I've just realized how weak my funnel was and I'm looking for inspiration. My audience is B2B and made of digital agency owners, project managers and freelance developers. Once they register in my application, they enter into a sophisticated email automation cycle with various CTA. They get between 4 and 7 emails during the first 14 days. After the expiration of the trial, they receive over the time useful email of content twice a month. Beside this, we try to add our leads on LinkedIn where we post useful/funny content 2 twice a week. How would you power up this funnel? What are your best tips and tricks?
