The verdict

AWeber

Best for the cheapest paid entry to email

AWeber starts at $15/mo versus Klaviyo's $30, so for straightforward email marketing on a tight budget it costs less to get going. It covers the core kit both share: drag-and-drop builder, templates, automation, segmentation, landing pages and A/B testing. The trade-off is no free plan, and no SMS or transactional email.

Full profile

Klaviyo

Best for free start plus SMS and ecommerce

Klaviyo has a free plan (250 profiles, 500 sends/mo) to start at no cost, plus native SMS and transactional email that AWeber lacks. Its segmentation spans hundreds of data points and it ships 350+ integrations with abandoned-cart and revenue-attribution flows. The paid entry is higher at $30/mo versus AWeber's $15.
