Cold email makes everything else a lot easier.
Especially Meta ad retargeting.
You drive a ton of interested traffic to your site.
A lot of people will not respond to the email. They will not book the call.
But they still clicked.
Now you have pixeled them.
You already know they are interested, so you can build a retargeting pool.
And run really low cost ads at people who have already shown interest.
Retargeting ads are far cheaper and more efficient.
If you build that pool with cold outreach, you make all of it more efficient.
