Omnisend vs Klaviyo below 5,000 contacts

A “contact” does not mean the same thing in both tools. The important question is which people count toward your monthly bill and how you stop old or unusable records from counting.

At 250 contacts, the free plans are very similar

Both current free plans allow up to 250 marketable profiles or contacts and 500 email sends per month. That is enough to build basic forms, flows, segments, and a campaign, but only two complete full-list sends in the simplest case. Automations consume the allowance too.

Each platform counts contacts differently

Omnisend sets its tier from subscribers plus non-subscribers in the account on the billing day. Klaviyo bills email around active profiles that can receive email; suppressed profiles do not count. Either one can be cheaper depending on list quality, consent status, customer imports, and how your other apps create records.

Count every email, including automations

Omnisend Standard currently provides 12 email credits per billable contact each cycle. Klaviyo says email plans include 10 times the maximum profiles in the selected plan. A merchant sending two campaigns per week can still use a large share of either allowance once welcome, browse, cart, checkout, post-purchase, and win-back flows are active.

Estimate campaigns and automated emails separately. Add room for resends, holiday peaks, and list growth. If that total exceeds a plan, compare the real upgrade price instead of the homepage starting price.

Price text messages separately

For Omnisend subscriptions started on or after May 4, 2026, Standard does not include SMS. New Pro subscriptions can buy SMS with volume pricing. Klaviyo prices mobile messaging through credits affected by destination and carrier fees. If SMS matters this quarter, request a matched-country quote from both vendors rather than treating an included dollar amount as equivalent reach.

When Omnisend is the stronger first choice

Choose Omnisend first when you want to set up the main ecommerce emails quickly, the 12-times Standard allowance covers your volume, and you do not need a specific Klaviyo feature. Extra features only matter when someone will use them.

When Klaviyo deserves the extra evaluation

Try Klaviyo when your team will use its deeper customer events, profile management, targeting, reporting, or broader marketing tools. At this list size, an advanced feature nobody uses is simply another cost.

A fair 90-minute trial

1. Use the same clean, consented test audience in both platforms.
2. Connect Shopify and verify the same core events arrive.
3. Build welcome, abandoned-checkout, and post-purchase flows.
4. Recreate one segmented campaign and inspect mobile editing.
5. Record build time, missing fields, reporting clarity, and the current plus next-tier quote.

Frequently asked questions

Which is cheaper below 5,000 contacts?

There is no honest universal answer. The current bill depends on each platform’s countable audience, the exact tier boundary, email volume, SMS mix, and promotions. Price the same cleaned audience in both live calculators.

Can I stay on either free plan?

Yes, while remaining at or below 250 eligible contacts or active profiles and 500 monthly email sends. That allowance is best treated as evaluation capacity rather than a normal growth plan.

Should I suppress inactive contacts just to cut cost?

Do not suppress contacts only to lower the bill. Preserve consent history, follow applicable rules, and consider whether re-engagement is still worthwhile. Use permission and recent engagement instead of removing everyone older than an arbitrary date.
