Great question @Harjot Singh! My go-to is LinkedIn but not for outreach. Once I find a brand I want to reach out to, I use LinkedIn paired with Apollo.io. With the Chrome extension installed for Apollo, I then go to the brand page on LinkedIn, go to People tab, then find the decision makers for that company. i.e. CEO, CMO, Marketing Director, Influencer Marketing, etc. I then open the Apollo.io extension and click Get Email which gives me the email addresses for those decision makers. I then reach out via email with my pitch! 👊
