Zora adds a bit more power to it’s newsletter with topics. When used on an article or product page it will automatically use the tags from the product or article as topics. Category tags are automatically shown and the membership tag is excluded. If you prefer not to auto show tags based on content you can also assign the newsletter custom tags.
By default the newsletter will add a source tag which let’s you know where your customers originated from without having dive deep into analytics code. You can use Shopify’s customer admin to get additional information about your audience.
