How Can I Connect with IT Professionals as a Salesperson?

Hey everyone, I'm a salesperson (wish I was in IT) trying to sell products to IT teams, but I'm really struggling to make a connection. I can't figure out the best way to reach out—should I be calling, leaving voicemails, sending emails, or trying LinkedIn? My company is quite reputable and we offer valuable services like global device procurement, configuration, management, and recovery, especially needed in challenging markets like Brazil. Despite there being clear pain points that our product addresses, I feel like IT professionals just aren't interested. I'm genuinely seeking your advice on how to change this dynamic. Any tips would be greatly appreciated!
