Klaviyo Alternatives 2026: 5 Free Options
Klaviyo alternatives: Brevo, MailerLite, Omnisend, listmonk and 1 more. Prices and licenses checked October 22, 2026.
•3 min read•Email Marketing & Newsletters
Verdict:Klaviyo's free plan is tight: 250 active profiles and 500 email sends a month, and going over can stop you sending until you upgrade or the cycle resets. Its paid price is not listed as a flat number, which makes budgeting harder than it should be. Leave if you are a small store or newsletter hitting that ceiling, or if you pay for ecommerce depth you do not use. Brevo is the easiest step: 300 emails a day on its free plan means roughly 9,000 a month if you spread them, though the daily cap bites on launch days. MailerLite gives 2,500 emails a month to 250 subscribers and is the calmer editor. Omnisend targets the same ecommerce shops with identical free limits, so it is the closest like-for-like swap, but its paid price is only shown as a three-month promotion. If cost per contact is the real problem at scale, listmonk (AGPL-3.0) and Mautic (GPL-3.0) remove the per-profile meter entirely, at the price of running servers, a sending provider and your own deliverability. The trade-off that matters: Klaviyo's strength is store data feeding segments and flows, and none of these replicate that wiring without extra setup. Test migration and deliverability before you commit to any of them.

Why people look for Klaviyo alternatives
Klaviyo's free plan stops at 250 active profiles and 500 emails a month, plus $5 of mobile messages and $5 of Composer usage. Past those limits the FAQ says sending may pause or stop until the next billing cycle or until you upgrade. Paid tiers are priced through a calculator rather than a flat list price, so the bill depends on your profile count and message volume, which is hard to predict early.
