I believe Facebook lead ads are the secret weapon for growing email lists. Email is so powerful, effective and affordable, that I often recommend this for my clients. I use Facebook and Instagram lead ads to find people who are most likely to sign up for my email lists. Email can be so effective at generating leads and making great customer experiences, there is no reason not to do this. It’s simple too.

How to do this in Facebook Ads Manager:

Create a Lead Generating Objective Campaign.
Apply the audience, budget, and the settings you want.
Create a new Form with a field for a “Name” and one for “Email.”
Create the Lead Ad creative and include the form.
Publish.

You’ll be able to track the impressions, clicks and be able to download the list of new email subscribers to add to your email list. Downloaded the list into a CSV format and manually enter into your email list, or use Salesforce, Hubspot or a tool like Zapier to push customer email addresses to your email list.
