Please, please stop doing cold outbound. It used to sort of work, never that well, but know because of so much automation and AI and bad actors, cold outbound is pretty pointless.
Here's what you should do instead.
Warm outbound.
Warm outbound is a process of identifying people who have shown some interest or intent, but have yet to raise their hand for a meeting.
This could be anything from engaging with several of your most recent LinkedIn posts to people who have consistently opened and clicked on a company's newsletter.
Or people who have downloaded several content assets or attended recent webinars.
The key is they are taking some type of explicit action.
You could rank the quality of those actions by looking at opportunity and closed won/closed lost data, if you have enough of the data to feel confident the results are correlated.
How you reach out is the next thing.
You need to be thoughtful and not just enroll the person into some random sequence. That will do you no good.
Instead, a person at your business should do some research, with the help of an AI assistant, and then craft a compelling email to send to the person, and set up a series of tasks to complete over the next 30 to 60 days to try and get the warm lead to respond.
The key is doing the research, reaching out using two or more channels, and tailoring the message to what they were engaging with and your assumed understanding of their intent and/or problem.
