Klaviyo serves e-commerce brands (Shopify stores, DTC retailers) who need email marketing automation with SMS and push. Push is a secondary feature—Klaviyo prioritizes email campaigns, flows, and e-commerce segmentation (purchase history, CLV, product recommendations). At 10K contacts, Klaviyo costs $150-400/mo. SashiDo targets developers building any app type (social, productivity, gaming, SaaS) who need push-first infrastructure. Hosting from $4.95/mo includes unlimited push with complete backend. Different tools for different needs: Klaviyo for e-commerce email marketing, SashiDo for developer infrastructure with push. See our transparent pricing.

Klaviyo is purpose-built for e-commerce: Shopify, WooCommerce, Magento, BigCommerce integrations. Segmentation focuses on purchase history, abandoned carts, product views, customer lifetime value. Flow builders optimize for retail lifecycle (browse abandonment, post-purchase, win-back). Push notifications exist but are a secondary feature compared to email/SMS. Best suited for e-commerce marketing, less ideal for non-retail apps. SashiDo works with any app type via REST API. Universal push infrastructure, flexible MongoDB segmentation, Cloud Code for any business logic. Works across all app categories.

Klaviyo charges based on total contacts (email addresses, phone numbers, push subscribers combined): $20/mo for 500 contacts, $60/mo for 1,500, $150/mo for 5,000, $350/mo for 10,000, $700/mo for 20,000. Costs escalate quickly with list growth. SashiDo charges for infrastructure usage (API requests, database size, traffic), not contact counts. At 50K users: Klaviyo ~$500-1,000/mo vs SashiDo ~$25-50/mo. Pay for resources consumed, not arbitrary contact metrics. Predictable scaling without contact-based pricing traps.

If you need sophisticated email marketing campaigns, Klaviyo is purpose-built. If you need push infrastructure with backend, SashiDo is better value.
