Why pricing tiers are a scam
Most email providers use tiers to extract maximum value from each customer segment. Pay $20/month for 50K emails, but only send 10K? You're subsidizing their other customers. Need 60K emails? Jump to the $90/month tier. That's a 350% price increase for 20% more emails.
We don't do tiers. You pay exactly $0.50 per 1,000 emails. Send 1,000 emails? Pay $0.50. Send 1,000,000 emails? Pay $500. No artificial boundaries. No wasted money on unused capacity.
Why can we do this? No sales team. No complex billing logic. No customer success managers trying to upsell you. We built efficient infrastructure and pass the savings to you.
Pricing made for how you actually build
For AI agents
Your AI sends emails when it needs to. Maybe 10 today, 10,000 tomorrow. Pay for exactly what gets sent. No tier to accidentally exceed.
For vibe coders
Ship fast, iterate faster. Test with real emails without worrying about monthly limits. $5 credit means 10K test emails before you pay anything.
For production
Predictable costs at any scale. Same $0.50/1K rate from your first email to your billionth. No surprise tier jumps, no "contact sales" walls.

Competitor pricing from public sources as of 2025. Ark pricing is pure usage—you only pay for emails actually sent.
Why we can offer the lowest price
No sales team
We don't have salespeople calling you about "enterprise plans." No commissions to pay = lower prices for you. Our best price is public.
No negotiations
The startup sending 10K emails pays the same rate as the enterprise sending 10M. You already have our best price. No meetings required.
No feature gates
Every feature is available from day one. MCP server, webhooks, analytics, unlimited domains—all included. We don't charge extra for "premium" features.
No wasted capacity
Tier-based pricing forces you to pay for capacity you might not use. Our usage-based model means you pay for exactly what you send, nothing more.
Questions
Is there really no monthly fee?
Correct. You pay $0.50 per 1,000 emails sent. Send nothing, pay nothing. No base fee, no minimum, no commitment.
How does the $5 welcome credit work?
Every new account gets $5 in credit automatically. That's enough for ~10,000 emails. Use it for testing, development, or production—we don't care. It never expires.
Can I get a volume discount?
No, because you don't need one. At $0.50 per 1,000 emails, you're already paying less than most "negotiated enterprise rates." The price is the price—same for everyone.
Do I need a credit card to start?
No. Sign up, get your $5 credit, start sending. Add a card when you're ready to go beyond the welcome credit.
What if I send millions of emails?
Same price: $0.50 per 1,000. At 1 million emails, you pay $500. At 10 million, you pay $5,000. No tiers, no sales calls, no contract negotiations.
Is the MCP server really included?
Yes. All 26 tools. Works with Claude, Cursor, Windsurf, VS Code, and any MCP client. No extra charge, no "AI add-on tier."
How do I know you won't raise prices?
We built our infrastructure to be profitable at this price point. No VC pressure to "monetize" later. This is our business model, not a loss leader.
What happens if my balance runs out?
Emails are rejected until you add more credit. Enable auto-recharge in your dashboard to automatically top up when your balance gets low—never miss an important email.
