Hi, I am assuming you do your own ad creations. So, If you have a list of email ids (Database) you could use the database and re-market to all the people on your list.
So, how does Remarketing work on Social Media – I will take the example of Facebook – here I am sharing the steps for using an email list for targeting your ads ->
Go to your Facebook account and load the ads manager through the “create ads” option in the options menu.
To create a custom audience simply click on the “create audience” drop down menu above your saved audiences dashboard and then click on “custom audience”. So what is a custom audience?
Such an audience can be formed by people that have bought from you before, or people in your email lists, or simply people that have engaged with your business before in one way or another, and that you can target with a Facebook ads campaign.
As you can see, there are several ways to target people with a custom audience. You can target people in a “customer file”, which will allow you to target people according to customer or subscriber data saved on a file.
Upload your customer file you will be given the options to “add customers from your own file or copy and paste data”, to “import from MailChimp” or to add a “customer file with lifetime value”.
Thus, you could use their email ids and show your ads to only those people on your list.
