Klaviyo alternatives in 2026, priced by use case

Klaviyo's Email plan runs $20 a month at 500 active profiles and $150 at 10,000, and no annual prepay exists to soften either figure: the help center states that self-serve plans bill monthly, full stop. Since February 18, 2025 your tier has to match your profile count, so the invoice follows list growth without anyone approving it. Almost nobody leaves because the software disappointed them. They leave because the bill acquired a will of its own. Below are five replacements at prices we checked in August 2026, sorted by the job you are actually doing, with the wider market math in our email pricing guide.

Why people leave Klaviyo

The curve climbs itself. The Email plan steps $20 at 500 active profiles, $30 at 1,000, $45 at 1,500, $100 at 5,000, $150 at 10,000, all monthly. That last rung is $1,800 over a year with no prepay lever to pull, which is unusual: MailerLite at the same 10,000 subscribers is $961.20 a year on annual Comfort, Mailchimp Essentials is $1,320 on monthly, and a flat $50 domain is $600. Before February 2025 an account could sit on a cheap tier while the list quietly outgrew it. That ended when Klaviyo began requiring the plan tier to match or exceed the active profile count, upgrading accounts automatically at the start of the next cycle. Growth is now a billing event.

The send allowance is tied to the list, not to your calendar. Each tier includes roughly ten times your active profile count in monthly email sends. A 1,000-profile store that mails three times a week is near 13,000 sends a month against a 10,000-send allowance, which produces upgrade prompts in a month when not a single new customer signed up.

The upsell surface keeps widening. SMS is a credit meter bolted onto the email plan: a $15 monthly minimum buys 1,250 US credits, the Email and SMS bundle opens at $35 a month, and credit burn varies by country and message type. As of August 2026 the pricing page sells a whole B2C CRM (Marketing, Service, Data and Analytics, Customer Agent, plus Composer credits), and its default configurator total displays $45, which is the 1,001 to 1,500 tier rather than the entry price. One more mechanic to know before you plan hygiene around the bill: unsuppress a profile and you cannot re-suppress it for 90 days, so it stays billable for at least a quarter.

In fairness, Klaviyo does the honest thing where it matters most. Suppressed and unsubscribed profiles leave the billable count once processed, so cleaning your list genuinely lowers your invoice, which is more than Mailchimp will say. The free tier is a real trial too: full flows and segmentation up to 250 profiles and 500 sends a month, with email support for the first 60 days.

The five alternatives

1. LetterDuck (that's us)

LetterDuck is an email workspace for one domain at a flat $50 a month. Every address on the domain lands in a threaded team inbox where anyone can reply as any address, and the newsletter composer ships one designed template. Deliverability is run in code rather than handed to you as a checklist: SPF, DKIM, and DMARC configured on your domain, a warm-up throttle that opens a new domain at roughly 150 sends and reaches about 1,100 a day by day seven, automatic suppression of bounces and complaints checked before every send, and RFC 8058 one-click unsubscribe stamped on every campaign.

The limitation is the whole reason this section is first rather than last: we are not an ecommerce automation tool and we are not trying to become one. No store integrations, no cart or browse-abandonment flows, no predictive lifetime-value scoring, no revenue attribution, no SMS, and no self-serve signup while we onboard in waves. If your Klaviyo account earns money while you sleep, that money does not follow you here. If your Klaviyo account is a mailing list wearing an ecommerce coat, the flat rate is the point. Newsletter creators tend to recognize themselves in the second sentence.

Price (August 2026): $50 per month per domain, unlimited subscribers, unlimited addresses, unlimited teammates.

2. Omnisend: the closest like-for-like

Omnisend sells the same shape of product to the same buyer: ecommerce automation, contact-based billing, email plus SMS. Its own help center article "Omnisend Pricing Plans 2026" (checked August 2026) puts Standard from $16 a month with email credits of twelve times your contact count per cycle, and Pro from $59 a month with unlimited sends. Two details from that same page are worth reading before you migrate: SMS is closed to new Standard subscribers and lives on Pro as an add-on from $0.007 per message for subscriptions after May 4, 2026, and a three-month prepay knocks 30% off, which is a real discount where Klaviyo offers none. Third-party trackers put Standard nearer $70 a month at 5,000 contacts and $130 at 10,000 (Retainful's Omnisend pricing breakdown, updated February 16, 2026), so run the calculator with your own count rather than trusting the starting price.

Price (August 2026): Standard from $16 a month, Pro from $59, both stepping with contact count.

3. Mailchimp: the generalist with the deepest feature list

Switch here if you want marketing machinery without ecommerce specialization: up to 200-step journeys, A/B and multivariate testing, and the largest integration catalog in the category. Two things make it a lateral move rather than an escape. Mailchimp counts unsubscribed and non-subscribed contacts toward your bill until you archive them by hand, which Klaviyo does not do, and its sends are capped at ten times contacts on Essentials just like Klaviyo's. The 50%-off promo covers twelve months, then the sticker returns. Tier detail is in our Mailchimp pricing breakdown, and the direct matchup is refereed in Klaviyo vs Mailchimp.

Price (August 2026, monthly billing): Essentials $13 at 500 contacts, $26.50 at 1,000, $75 at 5,000, $110 at 10,000.

4. Brevo: pay for sends, not stored profiles

Brevo turns the billing question around. Contacts cost nothing (the free plan holds 100,000 of them) and you buy email volume instead, which suits any store sitting on a large dormant customer file it mails monthly. A 10,000-profile list mailed weekly is 40,000 emails a month, which Brevo prices at $497 a year on annual Starter against Klaviyo's $1,800. Read the gates first: the Brevo logo stays on your mail unless you add $12 a month on Starter, marketing automation requires the Standard tier, Starter is single-seat, and the free plan's cap is 300 emails per day rather than per month. Our Brevo pricing analysis has the volume ladder.

Price (August 2026, annual-billing effective): Starter $8.08 a month for 5,000 emails, $28.75 for 20,000, $41.42 for 40,000.

5. MailerLite: the value pick for a content list

MailerLite covers campaigns, automations, landing pages, forms, and a website builder on its cheapest paid plan, and it excludes unsubscribed and bounced contacts from the billable count. For a store that mostly sends broadcasts and one welcome sequence, it does the job at roughly half the price. Two cautions dated June 2026: the paid tiers were repriced upward by about 10 to 30% with no grandfathering, existing accounts move to the renamed Comfort and Power plans from August 13, 2026, and subscriber counting is cumulative within a cycle, so pruning mid-month does not lower that month's bill. Full tiers sit on our MailerLite pricing page.

Price (August 2026, annual-billing effective): Comfort $10.80 at 500 subscribers, $17.10 at 1,000, $44.10 at 5,000, $80.10 at 10,000.

The numbers side by side

Public list prices, August 2026, annual billing where offered. Klaviyo: Email plan, billed by active profile count. Klaviyo publishes no annual discount on self-serve plans, so monthly is the effective price. Mailchimp: Essentials on monthly billing, the cheapest paid tier. Standard runs $20 to $135 across the same contact counts. First-year promotional discounts are excluded. LetterDuck is $50 per domain, flat, unlimited addresses and subscribers.

Read that table with one correction in mind. The Klaviyo column is monthly billing because no other billing exists, and the Mailchimp column is monthly because Mailchimp publishes no per-tier annual rates, so neither number has an annual discount hiding behind it. Every other provider on this page does: MailerLite takes 10% off for annual, Brevo 10%, Omnisend 30% for a three-month prepay. At 5,000 subscribers MailerLite's discount alone is $58.80 a year ($49 monthly against $44.10 annual effective), money Klaviyo gives you no way to save.

When Klaviyo is actually the right choice

Stay on Klaviyo if the flows are earning. Real-time storefront sync, predictive lifetime-value and churn scoring, and revenue attributed to each behavioral flow are the reason the product costs what it does, and no flat-rate email workspace attempts any of it. The unified profile matters too: email, SMS, MMS, and mobile push running off one customer record is genuinely hard to assemble from parts, and Omnisend is the only tool on this page that even tries.

So run one number before you decide. Open the flows report, total the revenue attributed to automated flows over the last 90 days, divide by three, and put that monthly figure next to your tier price. If it is comfortably larger, cancel nothing and go raise your send frequency instead. If it is small, or if the honest answer is that you send a weekly letter and answer replies in a separate inbox, you are renting ecommerce infrastructure to do postage, and one of the other tools above does postage for less.
