Klaviyo Is An Email And SMS Specialist. Nexus Commerce Puts Follow-Up Next To The Sale.
Klaviyo is one of the deepest email and text marketing tools you can buy, with segmentation, reviews and AI built around it. It isn’t a store or a register, though. This page compares Klaviyo for email and SMS with the marketing built into Nexus Commerce, for businesses whose follow-up is calls, texts and emails to the customers they already sell to.
Public pricing and features checked October 31, 2026. Prices change, so confirm on Klaviyo’s site before you decide.
Which One Fits Your Business?
Choose Klaviyo if
Email and SMS campaigns drive a big share of your revenue, your list is large, and you want segmentation, reviews and dedicated marketing tools on top of the store you already run.
Choose Nexus Commerce if
Your follow-up is with accounts and repeat customers: calls, texts and emails tied to the same contact, pipeline, quote and order history, in the system where you sell.
Be honest about the mix
If you send campaigns to tens of thousands of shoppers, Klaviyo is the better tool. If you mostly follow up on quotes, accounts and walk-ins, Nexus Connect may cover it without a separate marketing subscription.

- Klaviyo Email by active profiles, per month: 500 = $20, 1,000 = $30, 2,500 = $60, 5,000 = $100, 10,000 = $150. The Marketing plan shows an estimated $90 a month at 500 profiles.
- Nexus Commerce: Core $249 + Nexus Connect $39 = $288 a month for the store, POS, contacts, pipelines, calls, texts and email at one location.
For email alone, Klaviyo is cheaper at every volume in this table, it has a free plan for up to 250 active profiles, and it’s the deeper marketing tool. Nexus Connect makes sense when the same team takes calls, sends texts and follows up on quotes, because it bundles calling, which Klaviyo’s pricing page doesn’t list, and it works from the same contact record as the order. Connect only runs on a Nexus Commerce plan, so it’s the better buy if you’d use the plan anyway. If all you need is newsletters, Klaviyo is the better buy.
Klaviyo prices come from its pricing calculator and plan cards, labeled per month; the page doesn’t say whether that is monthly billing. Klaviyo’s price is set by active profiles, not sends, so a large list costs more even at low volume. Its Marketing plan price is shown only at 500 profiles on the plan cards. A limited-time first-month discount is ignored. Nexus Commerce figures are monthly list prices with monthly billing. Connect usage stops at the plan limit and prompts an upgrade; business phone numbers are $2 a month local or $5 toll-free.
