Apply customer tag across data set

[MartinGlenware]

Hi

Im looking at "Tag employee customer accounts by email domain" and was wondering if I can apply the flow across the customer set? Or just on new customers?

Thanks

Hi, 

It will work only for new customers, for existing customers you can tag them by doing a search by domain name for example @Gmal.com this will filter out the customers with this domain, you can then select all the filtered customers and add a tag.

Thanks,
