Built for stores. Priced like it, too.
Klaviyo is the strongest e-commerce email platform — at $150/month for 10,000 profiles and $720/month at 50,000. If you don't need deep store analytics, Sendra sends the same email for about $22.
How Klaviyo charges
Klaviyo prices by active profiles (since February 2025) with automations, segmentation, and predictive analytics included on every paid tier. Email sends are capped at roughly 10× your profile count per month, SMS is a separate add-on, and if your profile count grows past your tier, Klaviyo automatically upgrades your plan at the next billing cycle. As of 2026 the email plan runs from $30/month at 1,000 profiles to roughly $1,380/month at 100,000; above 250,000 it's custom pricing.
How Sendra charges
Sendra is flat software pricing: free for your first 1,000 contacts, then $20/month for unlimited contacts. Delivery runs through your own Amazon SES account, billed directly by Amazon at roughly $1 per 10,000 emails. Your list can grow 100× without your software bill moving.

When Klaviyo is the better choice
For e-commerce brands where email directly drives store revenue, Klaviyo is genuinely the category leader:
- You run a Shopify (or similar) store and want abandoned-cart, back-in-stock, and post-purchase flows driven by real order data.
- You need revenue attribution per email and per flow — Klaviyo's e-commerce reporting is unmatched.
- You want predictive analytics: customer lifetime value, churn risk, expected next order date.
- You run coordinated email + SMS campaigns from one system.
