Klaviyo and AWeber are not natural competitors. Klaviyo is a data-driven e-commerce marketing platform built around purchase behavior and store integrations. AWeber is a straightforward email tool that has served small businesses and creators for over two decades.
If you run an online store, the choice is likely Klaviyo. If you do not, AWeber's simplicity, free plan, and reliable support make it a reasonable option for basic email needs.

The core difference
Klaviyo is worth the premium if you are driving measurable e-commerce revenue through email. Its purchase-based segmentation, cart abandonment flows, and revenue attribution reporting are built around the needs of online stores.
AWeber is worth considering if you want something simple, reliable, and with genuine phone support. It is not built for e-commerce depth, but it handles newsletters, welcome sequences, and basic campaigns well.
Pricing at scale
Both have free plans, but their paid pricing diverges significantly. AWeber's paid plans start at $15/mo. Klaviyo can reach $100/mo or more at moderate list sizes because its pricing scales with both contacts and emails sent.
For non-e-commerce users, Klaviyo's pricing is hard to justify.
Support
AWeber is well-regarded for customer support, including phone support on paid plans. This is rare at this price range. Klaviyo has solid help documentation and email/chat support but no phone option.
Choose Klaviyo if...
- You run an online store and want revenue-driven email marketing
- Deep Shopify or WooCommerce integration is important
- You want SMS and email together in one platform
- Purchase-based behavioral segmentation is core to your strategy
Choose AWeber if...
- You are not in e-commerce
- You want a free plan with room to grow
- Phone support is important to you
- Simplicity and reliability matter most
The bottom line
Klaviyo for e-commerce businesses that will use its data features. AWeber for businesses that want a simple, reliable tool with good support and a free starting plan.
