  • Built-in SMS credits on Pro (subscription value back in SMS). :contentReference[oaicite:1]{index=1}
  • Strong ecommerce deliverability, with benchmark inbox placement around ~97% in realistic Shopify scenarios. :contentReference[oaicite:2]{index=2}
  • Fast time-to-value with pre-built ecommerce flows (welcome, cart, browse, post-purchase).

Pricing deep dive Omnisend vs Klaviyo 2026: real costs at 1k, 5k, and 10k contacts

Both Omnisend and Klaviyo use contact-based pricing, but their curves behave differently once you add SMS and increase sending volume.

Omnisend pricing in 2026 (email + SMS)

Based on Omnisend’s official pricing and recent third-party breakdowns, here’s what you can expect in 2026: :contentReference[oaicite:18]{index=18}

• Free plan – up to 250 contacts and 500 emails/month. Great for early validation.
• Standard plan – email-focused, 12× email sends per contact, starting around $11–16/month for small lists.
• Pro plan – unlimited emails plus SMS credits ≈ your monthly subscription (e.g., pay $90, get ~$90 in SMS), which materially reduces your net cost if you actively use SMS.

Typical pricing snapshots (Standard & Pro, email only, USD/month):

• 5,000 contacts – ~$81 (Standard), ~$90 (Pro, unlimited emails). :contentReference[oaicite:19]{index=19}
• 10,000 contacts – ~$132 (Standard), ~$150 (Pro). :contentReference[oaicite:20]{index=20}

Because Pro includes SMS credits, many ecommerce brands effectively “get SMS included” up to a realistic threshold of sends per month.

Klaviyo pricing in 2026 (email + SMS)

Klaviyo also offers a free plan up to 250 contacts with 500 emails/month, then moves to separate Email and Email + SMS tiers. :contentReference[oaicite:21]{index=21}

• Email only – starts around $20/month at ~500 contacts, scaling steeply with list size.
• Email + SMS – bundles email sends with a fixed SMS credit pool; upgrading SMS credits often jumps you into a higher pricing band. :contentReference[oaicite:22]{index=22}

Real-world examples from recent 2025 data: :contentReference[oaicite:23]{index=23}

• 500 contacts – ~$20/month (Email) or ~$20–35 (Email + SMS depending on credits).
• 5,000 contacts – often around $100–145/month once SMS credits are included.
• 10,000 contacts+ – can reach $150–330+/month depending on email volume and SMS credits.

The key pattern: Klaviyo’s pricing escalates faster when you rely heavily on SMS, while Omnisend’s Pro plan keeps your total messaging cost more predictable.

Omnisend vs Klaviyo 2026 deliverability: inbox placement & revenue per 1,000 sends

Deliverability isn’t just about “do emails send?” – it’s about how many land in the inbox, not spam. Industry reports still show average deliverability around 83–85%, with 10–20% of marketing emails never reaching the inbox. :contentReference[oaicite:25]{index=25}

For ecommerce brands using Omnisend and Klaviyo, realistic (not “best case only”) benchmarks look like this, assuming proper setup and solid list hygiene: :contentReference[oaicite:26]{index=26}

• Omnisend – around ~97% inbox, ~1% spam, ~2% missing on well-managed ecommerce lists.
• Klaviyo – around ~93% inbox, ~4% spam, ~3% missing in similar conditions.

In addition, internal analysis from ChooseEmailMarketing found that revenue per delivered email for ecommerce flows typically averaged:

• Omnisend – ≈ €0.91 per delivered email
• Klaviyo – ≈ €0.72 per delivered email

Final verdict: Omnisend vs Klaviyo 2026

If you’re a typical Shopify or WooCommerce brand, Omnisend is the safer, higher-ROI bet for 2026. You get predictable pricing, built-in SMS credits on Pro, high ecommerce deliverability, and pre-built flows that generate revenue with minimal setup.

Klaviyo remains a fantastic choice for advanced, data-heavy teams that will fully exploit its experimentation and analytics capabilities. But for most lean ecommerce teams, the additional complexity and higher total cost often don’t translate into meaningfully higher profit.
