nitrosend vs Klaviyo
Klaviyo built the enterprise ESP. We're building what comes after it. Here's how we compare on the things that matter.
| nitrosend | Klaviyo | |
|---|---|---|
| Approach | ✦ AI-native | Dashboard-first, AI add-ons |
| Primary interface | ✦ MCP + API | Web dashboard |
| Contact pricing | ✦ Unlimited, always | Per-contact tiers (costs scale with list) |
| Pricing model | ✦ Pay per send | Per-contact + per-send overages |
| AI capabilities | ✦ Full-stack AI agent
Writes, designs, segments, sends, learns | Subject line suggestions, predictive analytics |
| MCP support | ✦ Native
Claude, ChatGPT, Cursor, Codex, Gemini | None |
| BYO infrastructure | ✦ Yes
Sending + AI keys | No (conflict with revenue model) |
| Setup time | ✦ 5 minutes | Hours to days |
| Free plan contacts | ✦ Unlimited | 250 contacts |
| Starting price (paid) | ✦ $20/mo
25K emails, unlimited contacts | $20/mo 500 contacts only, scales steeply |
| At 100K contacts | ✦ $100/mo
Pro plan, 150K emails | ~$1,200/mo Per-contact pricing, before sends |
| At 1M contacts (enterprise) | ✦ ~$500-800/mo
Custom plan, 1M emails | $5,000-15,000+/mo Custom enterprise + Klaviyo One 20% surcharge |
The differences that matter.
No per-contact tax
Klaviyo charges more as your list grows. At 50K contacts, you're paying $720/mo before you send a single email. nitrosend charges for sends, not contacts. Import your entire list for free.
AI does the work
Klaviyo gives you AI suggestions. nitrosend's AI writes your campaigns, designs your emails, builds your segments, and optimizes your sends. You review. It executes.
MCP-native
Work from Claude, ChatGPT, Cursor, Codex, or Gemini. Your AI agent talks directly to nitrosend via MCP. No browser needed. Klaviyo has no MCP support and structurally cannot offer it.
Bring your own infra
Klaviyo can never offer BYO -- it conflicts with their revenue model. nitrosend's BYO plan lets you use your own sending (SES, Mailgun) and AI keys for maximum control and lower cost.
