Boostmail as a Klaviyo alternative
If you are leaving Klaviyo, the honest reason is almost always cost at scale, not quality, Klaviyo is genuinely good, with a 4.6★ rating across 3,200 Shopify reviews. The problem is its pricing climbs with your contact count: a bill that is fine at 1,000 contacts reaches roughly $150/mo by 10,000 and keeps rising. Boostmail is the recommended switch for stores that want the same core email and SMS, automations, and deliverability on transparent subscriber-based pricing, $60/mo at 10,000 active subscribers, with unlimited emails, plus AI-assisted content built in.
This guide is for merchants who have already decided to move and want to do it well. It covers why people leave Klaviyo (in their own words), which alternatives are genuinely worth considering, including ones that are not Boostmail, how the feature coverage compares, and exactly what the migration involves. Switch only if the trade-off fits your store: if you live inside Klaviyo\'s predictive analytics, that depth is the thing you would be giving up.
Why merchants leave Klaviyo
The pattern is consistent: stores adopt Klaviyo for its power, then re-evaluate when the bill scales faster than the value they extract from the advanced features. The cost driver is structural, Klaviyo prices on total contacts, so a growing or seasonally large list raises your monthly fee even if your sending volume is flat. The criticisms below are verbatim from real Klaviyo users; we do not paraphrase them into our own claims.
“The pricing gets very expensive very fast as your list grows.”
“Powerful but the learning curve is steep and it is overkill for a small store.”
The cost-at-scale point, plainly: as of 29 June 2026, Klaviyo runs about $30/mo at 1,000 contacts and about $150/mo at 10,000, per its Shopify listing. Boostmail is free to 1,000 active subscribers and $60/mo at 10,000, and bills on active subscribers rather than every contact you have ever collected. For a list with a long tail of inactive addresses, that difference compounds month over month.
The Klaviyo alternatives worth considering
Boostmail is our recommendation for cost-driven switchers, but it is not the only sensible option. Here is an honest read on the field so you can pick the one that fits your store.
Boostmail, transparent pricing, AI content, deliverability-first
Boostmail covers the jobs most stores actually use Klaviyo for, email and SMS campaigns, abandoned-cart and post-purchase flows, segmentation, a drag-and-drop builder, on a published subscriber-based curve with unlimited emails on paid plans. It bills on active subscribers, includes OpenAI-powered content generation from the free plan, and treats deliverability as a core feature: sender-reputation monitoring, SPF/DKIM/DMARC setup, and bounce and complaint handling. We build it, and we disclose that. It is the better fit for cost and simplicity; Klaviyo remains stronger on predictive analytics and integration breadth.

Omnisend, closest like-for-like, email + SMS bundled
Omnisend is the most direct Klaviyo substitute for stores that want email, SMS, and push in one tool. It is ecommerce-native, highly rated, and its pre-built automations work out of the box. It still prices by contact count, so the cost-at-scale concern that pushes merchants off Klaviyo applies to Omnisend too, if to a lesser degree at the lower tiers.

Avada Email Marketing, generous free tier, budget-friendly
Avada is the value option: a free plan with 12,000 emails a month and unlimited emails on paid tiers that start lower than Klaviyo. It is a sensible landing spot for a smaller store whose main grievance with Klaviyo is the monthly bill, though its analytics and segmentation are lighter.

Privy, strongest if on-site list growth is the priority
Privy is worth a look if the job you most want done is capturing email addresses on-site, its popups and forms are mature and well reviewed. As an all-round ESP it is less complete than Klaviyo or Boostmail, so it suits stores that pair it with another sending tool or have simpler campaign needs.

How to migrate from Klaviyo to Boostmail
Switching email service providers is mostly a careful, ordered process rather than a hard technical lift. The two steps that matter most are preserving consent on your contacts and re-authenticating your sending domain, get those right and the rest is straightforward.
-
Export your contacts and segments from Klaviyo
In Klaviyo, export your profiles (Lists & Segments → export to CSV) along with the segment definitions you rely on. Capture consent status and subscription source for each contact, you must preserve who opted in, and when, to stay compliant when you import them elsewhere. Note any custom profile properties you use in segmentation so you can recreate them.
-
Install Boostmail and import your list
Add Boostmail from the Shopify App Store (free to install). Import the CSV you exported, mapping email, consent status, and your custom properties. Because Shopify is the source of truth for orders and customers, Boostmail also syncs store data directly, so purchase history and customer records flow in without a manual export.
-
Recreate your flows and automations
Rebuild your core automations in Boostmail: welcome series, abandoned-cart and browse-abandonment flows, post-purchase and win-back. Do not try to clone every Klaviyo branch on day one, port the flows that actually drive revenue first, then add complexity. Keep your old Klaviyo flows live but paused until cutover so nothing lapses.
-
Re-authenticate your sending domain (SPF, DKIM, DMARC)
Authenticate the same sending domain in Boostmail by adding its SPF, DKIM, and DMARC DNS records at your registrar. This is the single most important step for deliverability: sending from an unauthenticated domain after a switch is the fastest way to land in spam. Boostmail walks you through each record and verifies them before you send.
-
Warm up and verify deliverability
Send to your most engaged subscribers first and ramp volume over a few days rather than blasting your whole list from a freshly authenticated domain. Watch Boostmail's sender-reputation monitoring, send a seed test to check inbox placement, and confirm bounce and complaint handling is active before you scale up.
-
Cut over and decommission Klaviyo
Once a few campaigns and your key flows are sending cleanly from Boostmail, switch your signup forms and any API integrations over, then pause Klaviyo sending. Keep the Klaviyo account read-only for a billing cycle so you can reference historical reporting, then cancel once you are confident nothing still depends on it.

Frequently asked questions
- Is Boostmail a good Klaviyo alternative?
- For most Shopify stores whose main reason for leaving Klaviyo is cost, yes. Boostmail covers the same core jobs, email and SMS campaigns, abandoned-cart and post-purchase automations, segmentation, and deliverability, on transparent subscriber-based pricing, with AI-assisted content included. Where Boostmail is not the better fit is at the enterprise end: if you depend on Klaviyo's predictive analytics or its largest integration directory, weigh that before switching.
- Why do merchants switch away from Klaviyo?
- The most common trigger is price as the contact list grows: Klaviyo's cost scales with contacts, so a bill that is reasonable at 1,000 contacts (about $30/mo) climbs steeply by 10,000 (about $150/mo) and beyond. Klaviyo itself is well rated, 4.6★ across 3,200 reviews, so this is usually about cost and complexity rather than a quality problem. The quotes on this page are from real Klaviyo users.
- Will I lose my email history or subscribers when I switch?
- You keep your subscribers, you export them from Klaviyo and import them into your new app, preserving consent status. Historical campaign reporting stays inside Klaviyo, which is why we recommend keeping that account read-only for a billing cycle after you cut over. Going forward, Boostmail reports on everything it sends, and because it syncs Shopify order data directly, purchase-based segments rebuild quickly.
- How long does migrating from Klaviyo to Boostmail take?
- For a typical store, the hands-on work is a few hours spread across a few days: an hour or two to export and import contacts and rebuild your key flows, then a short domain-authentication and deliverability warm-up window before you fully cut over. The pace is set by the warm-up, not the setup, ramping volume gradually after re-authenticating your domain protects your inbox placement.
- Is Boostmail cheaper than Klaviyo?
- At the volumes most growing stores reach, yes. As of 29 June 2026, Klaviyo is about $150/mo at 10,000 contacts; Boostmail is $60/mo for up to 10,000 active subscribers, with unlimited emails on paid plans. Boostmail is also free up to 1,000 active subscribers. Always confirm current pricing on each vendor's listing, and remember Boostmail bills on active subscribers, while Klaviyo bills on total contacts, so the gap depends on how much of your list is engaged.
