Virgosummer2 review for Klaviyo: Email Marketing & SMS

Lots of advanced customization for a small price. You can also use this app to create 'back in stock' buttons and alerts and NO extra cost. You need a little coding skill or they can help you. Compared to what Constant Contact gives you, this is way better. Some technical difficulties but overall a great app and no issues that would prevent you from sending a basic email right away.
