Every plan includes full stack emailing: Flows, Newsletter Campaigns and Transactional Email, plus our NitroWheel LLM and all agent integrations (Claude, ChatGPT, Codex, Cursor and others). All plans, including free plans, have full access to Nitrosend MCP/API/CLI. Pay for what you send, not who you store.
Daily allowances depend on your plan and sender standing. Strong list, domain and delivery evidence can raise standing, including on day one. Trusted receives the full plan allowance; available email credits, safety checks and delivery pacing still apply.

Free forever. Upgrade anytime. No credit card required.
No. Every plan includes unlimited contacts. You only pay for the emails you send. Charging per contact is a legacy model that punishes growth.
Yes. Free includes three brands, Pro includes five, Ultra includes ten, and Enterprise includes unlimited brands. Included email volume is account-scoped; sender reputation and capacity are isolated per exact sender.
Every Free account starts with 8,000 emails to send however you like - no credit card, no expiry. Once those are used, your monthly allowance kicks in at 500 emails per month, free forever.
On Pro, Ultra and Enterprise you can bring your own sending infrastructure keys (SendGrid, Resend, Amazon SES, Mailgun, Postmark) and your own AI provider keys (Anthropic, OpenAI). Same Nitrosend platform, your deliverability domain, your model account.
Pro, Ultra and Enterprise route your AI actions through the latest Claude, GPT and Gemini models as they ship. Free uses smaller models. You always get the best copy and segmentation quality on paid plans.
Yes. On Pro and above, Nitrosend branding is removable. Toggle it off in Brand > Sender. Your brand, not ours.
Dedicated IPs are available on Ultra and Enterprise at $50 per IP per month. Sending capacity still follows measured sender history and live delivery controls.
No. Verification is a separately authorized prepaid operation on every plan. In Contacts, choose Verify list, review the audience and maximum charge, then confirm. Strong, current valid results can help earn higher sender standing; buying credits alone cannot. Imports, schedules, and sends never start paid verification automatically.
We let you know before you hit your limit. Extra emails are billed at a fair per-100 rate ($0.19 on Pro, $0.15 on Ultra). Extra AI actions work the same way. No surprise charges.
Yes. Upgrade or downgrade anytime. Changes take effect on your next billing cycle. No contracts, no lock-in.
Yes. All plans, including free plans, have full access to Nitrosend MCP/API/CLI. Plan limits still apply to send volume, seats, AI action allowances, and paid add-ons, but we don't gate integrations behind tiers.
An agent sends under the same limits as a person. On Free, recipients per rolling 24 hours run from 100 to 5,000, set by sender standing, and the monthly email allowance applies. Extra emails on Pro and Ultra are billed at the per-100 rate above. Safety checks and delivery pacing still apply to every send.
It can start an upgrade, not pay for one. The nitro_manage_billing tool reads plans and creates a subscription checkout URL that an operator approves. Nothing is charged until a person completes that checkout.
No. Agent integrations (Claude, ChatGPT, Codex, Cursor and others) and MCP/API/CLI access are included on every plan, including Free. See the Nitrosend MCP server for how an agent connects.
One AI action = one generation from the model (a campaign draft, a segment suggestion, a subject line, an insight). Sending an email does not consume an AI action.
