Comparison
Klaviyo SMS pricing vs Signilio for sales teams
Published pricing, what a plan includes, the fees that show up later, and the shared inbox, side by side. Checked September 25, 2026.
The short answer
Klaviyo is an ecommerce marketing platform, and its SMS is priced like one: a monthly plan in dollars that works out to about 1.2 to 3 cents a send with carrier fees inside, on a toll-free number, with replies handled as helpdesk tickets. For an online store texting its subscribers alongside email it is excellent value and the data model is the whole point. For a sales team it is the wrong shape: no local 10DLC numbers in the US, a toll-free sender that reads as a brand rather than a rep, an inbox sold separately, and a public price that ends at 20,000 sends. Signilio's plans start at $34.99 a month for 1,000 texts on registered local numbers, with a two-way team inbox included. Klaviyo's published price is lower at the volumes it lists; the estimator shows both bills up to its published ceiling.

Billed per message segment per recipient: 160 characters, or 70 with emoji; an MMS is a separate, higher rate; the figures here are US toll-free SMS from the pricing calculator. Your negotiated rate may differ. Signilio figures use the plans on our pricing page, monthly billing. Nothing you type here is sent anywhere.
Where Klaviyo SMS is the better fit
- Online stores that already run email in Klaviyo and want SMS on the same customer data, segments and flows.
- A low all-in rate on toll-free sending, about 1.2 cents a send at 20,000 a month, with carrier fees bundled.
- A free plan, month-to-month billing and no per-user fee.
Where Signilio is the better fit
- Local 10DLC numbers registered for you, so a text arrives from a nearby area code rather than an 8xx number.
- A two-way team inbox included, with replies assigned to reps, not filed as support tickets.
- Published pricing at any volume, not a calculator that stops at 20,000.
- Built for outbound sales conversations rather than promotions to a subscriber list.
Common questions
- Is Klaviyo SMS cheaper than Signilio?
- It depends on volume and team size. For a team of five sending 10,000 one-segment texts a month from five numbers, Klaviyo SMS's cheapest published way to buy that is 10,000 sends, and the published bill comes to $125.00 a month. Note: Klaviyo sends from one shared toll-free number; additional local numbers are not offered in the US, so number routing across a team is not available. Signilio is $189.99 a month on its Pro plan for the same team, carrier fees included. Which one is cheaper changes with volume and team size, so the calculator above gives your own number.
- How much does Klaviyo SMS cost?
- Klaviyo sells a monthly mobile-messaging plan in dollars: on its public calculator, 1,000 US toll-free sends are $15 a month, 10,000 are $125 and 20,000 are $240, carrier fees included. Above 20,000 it does not publish a price. Signilio publishes plans up to 50,000 texts a month, from $34.99 for 1,000.
- Does Klaviyo offer 10DLC local numbers?
- Not in the US or Canada. Sending is on a complimentary toll-free number, or a short code at an unpublished extra cost. Signilio provides and registers local 10DLC numbers.
- Does Klaviyo have a team inbox for SMS replies?
- Replies arrive as tickets in Klaviyo's Helpdesk, a separately priced product, with a free basic Inbox. Signilio's two-way team inbox is included.
