Simple, yet able to customize to your business's needs
What do you like best?
I like how Privy intgrates well with shopify, such as including pop-ups with discount codes and follow up email sequences. you can also customize campaigns depending on whether a user is known, whether they have seen your campaign already, and more. there's also plenty of options and templates for customizing emails with product links, buttons, menus, and each link within the email automatically tracks the user so you don't need to create any UTM parameters yourself.
What do you dislike?
privy can look a little clunky in terms of design, and also if people sign up for your newsletter using a shopify email form, they won't necessarily end up on your privy subscriber list unless you manually add them using an excel file. also there is no option to save your brand colors within the email customization so you have to constantly enter the hex code of the colors you want to use. However, this can be avoided by saving an email that you designed as a template.
What problems are you solving with the product? What benefits have you realized?
acquiring new customers once they are on my site is easier now that I can use a pop up showing that new sign-ups can receive a discount on their first purchase. Also, after their first purchase I could send an email sequence showing them how to use my product as well as following up weeks later for a restock email sequence.
