Hire a virtual assistant to help with your lead generation tasks.
Your assistant can create and compile introduction and follow-up templates for cold email outreach, LinkedIn, or other social media if you don't already have them.
Your assistant can help you set up/manage tools for your lead generation needs (i.e. Apollo, GrowthGenius, Lemlist, CRMs, etc)
Weekly or monthly, your assistant can gather accurate data from your lead outreach campaigns so you can adjust your strategy as needed.
