How Klaviyo's per-contact pricing actually scales
Klaviyo's pricing curve is steeper than most merchants realize until they're already on it. The published tier slider (klaviyo.com/pricing/email) shows these data points for the Email plan:
| Active profiles | Klaviyo monthly cost |
|---|---|
| 250 | $0 (free tier) |
| 1,000 | $20 |
| 2,500 | $60 |
| 5,000 | $80 |
| 10,000 | $175 |
| 25,000 | $510 |
| 50,000 | $945 |
| 100,000 | $1,700 |
| 250,000 | $4,350 |
Notice the inflection at 5K contacts. From 0 to 5K, Klaviyo costs grow linearly and slowly — $80/month is bearable for most early-stage stores. Past 5K, the slope steepens: 10K is more than double, 25K is 6.4x, and 100K is 21x the 5K starting point. This is the moment when merchants start asking "wait, what am I actually paying for here?" and the answer is: every contact on the list, including the 60–80% who haven't engaged with an email in 90+ days.
The pricing model assumes contact-list size is a proxy for the revenue your email program drives. For high-end stores running deep behavioral segmentation across a sophisticated flow library, that assumption holds. For a typical sub-$1M Shopify store sending one newsletter per month and a couple of automation flows, it breaks down: you're paying Klaviyo's premium price even when you're using a fraction of its capability.
How Kovyo's per-email-sent pricing scales
Kovyo doesn't bill on list size. Your bill is determined by how many emails you actually send each month, mapped to a five-step plan ladder:
| Plan | Emails / month | Monthly price |
|---|---|---|
| Free | 500 | $0 |
| Starter | 5,000 | $9 |
| Growth | 10,000 | $29 |
| Scale | 25,000 | $79 |
| Pro | 60,000 | $199 |
The asymmetry matters at the same scale points the calculator above probes. A store with 5,000 contacts that sends 5,000 emails per month (one newsletter to the whole list) pays $80 on Klaviyo and $9 on Kovyo — same activity, same outcome, ~9× difference.
A store with 25,000 contacts that only sends to its 5,000 most engaged subscribers each month pays $510 on Klaviyo (priced on the full list size) and $9 on Kovyo (priced on the 5K actually sent). At that scale the gap is roughly 56× — and this is the shape of bill most merchants discover too late, after a year of paying for contacts they never email.
When each model wins
Klaviyo wins when…
- • You're doing $1M+/year and have a dedicated email marketer.
- • You need predictive AI segments, send-time optimization, or 50+ active flows.
- • Your list is small (under 1K) and your sending volume is high — Klaviyo Free is generous up to 250 active profiles.
- • You're already using Klaviyo SMS and want everything on one bill.
Kovyo wins when…
- ✓ Your list is bigger than your sending — common for small stores at the 5K–25K contact range.
- ✓ You want welcome flow, abandoned cart, and broadcast in one tool, no flow-editor PhD required.
- ✓ You're paying for popups separately and want them in the same dashboard.
- ✓ You don't want your bill to grow when your list grows — only when your sending does.
Frequently asked questions
Where does the Klaviyo pricing data come from?
The numbers are interpolated from Klaviyo's public pricing page (klaviyo.com/pricing/email), specifically the Email plan tier slider. Data points captured: 250 contacts = $0, 500 = $0, 1K = $20, 2.5K = $60, 5K = $80, 10K = $175, 25K = $510, 50K = $945, 100K = $1,700, 250K = $4,350. Snapshot date is shown beneath the calculator.
Why does Klaviyo charge by contacts and Kovyo charge by sends?
Klaviyo's bet is that contact list size correlates with revenue, so they price as a percentage of that. The problem is that small Shopify stores often have a 5,000-contact list with 2,000 active openers — they pay Klaviyo for the 3,000 dormant contacts every month even when they only send to the engaged half. Kovyo bills for actual sends, which means a 5K contact list that gets one newsletter per month costs the same as a 5K list that gets zero newsletters. Your bill grows when your sending grows, not when your collected list does.
Is this calculation accurate to the dollar?
Within $5–10 at most tier breakpoints. Klaviyo's actual quote at any specific contact count interpolates between their published tiers, so the calculator does the same. For a precise quote, klaviyo.com/pricing/email is canonical — but the calculator is accurate enough to show the order-of-magnitude difference, which is the point.
When does Klaviyo make more sense than Kovyo?
Klaviyo's deep segmentation, predictive AI, and integration ecosystem are genuinely better for stores doing $1M+ in revenue with a dedicated marketing team. The cost difference becomes worth it once you're sending high-volume campaigns daily and need the segmentation power. Below that threshold, Kovyo's per-send pricing typically wins by 4–8x.
What's the migration like?
CSV import. Most stores migrate from Klaviyo to Kovyo in under 30 minutes: export contacts CSV from Klaviyo, import into Kovyo, connect Shopify (auto-syncs new customers via webhook from that point forward), recreate the welcome and abandoned-cart flows. The flows use sensible defaults so you don't rebuild them from scratch.
