Pricing

Nitrosend is pay per send, never per contact — every plan includes unlimited contacts. MCP, REST API, CLI, AI copywriting, campaigns, flows, transactional, templates, and analytics are available on every plan, including Free. The Free plan includes 8,000 free emails up front, then 500 free emails every month. No credit card required.

Plans

Every brand can prepare one reserved Nitrosend brand-subdomain sender. It does not consume the customer-domain allowance. Hosted brand subdomains follow the same plan and standing allowances; they do not have an extra 1,000/day ceiling. Daily usage is pooled across the account's brands and includes capacity held for queued or unresolved sends. Email credits are separate from daily capacity. Provider limits, sender health and pacing still govern actual dispatch.

Standing combines attributable delivery history, current positive list verification, domain strength and account signals. Sufficient evidence can qualify an account on day one; payment alone does not earn trust. Trusted receives its full plan allowance without a second volume ramp. New sender contexts still require their first-send safety review, and Probation reviews each changed content identity. Existing reviewed Enterprise terms remain intact.

Email validation has no included allowance on any plan. It is an explicit prepaid operation and is never started automatically during import, scheduling, or sending.

Use Contacts → Verify list to choose all contacts in the Brand, a contact list, a segment, or selected contacts. Review the exact audience and maximum charge before confirming. Each operation accepts up to 100,000 candidates; larger audiences must be split into bounded lists or segments. Valid results can raise standing; invalid, catch-all and unknown results do not prove list quality. Buying prepaid credits alone does not raise standing.

The dashboard warns at 80% and at exhaustion. Free accounts receive the valid plan-upgrade action; accounts whose list evidence can improve receive Verify your list. API and MCP capacity responses expose the same reasons and actions. Queued campaigns wait for capacity; API callers should follow the returned retry time rather than repeatedly retrying or treating the refusal as delivered.

• Pro and above add BYO sending/AI keys, frontier AI models, removable branding, and priority support.
• Ultra and Enterprise add dedicated IPs as a paid add-on and more brands, seats, and domains.
• Enterprise adds SSO / SAML, a 99.9% SLA, a dedicated account manager, and tiered volume pricing for higher-volume senders.

For agents

If you are an AI agent or automation, fetch pricing programmatically instead of scraping the marketing page:

Plans and prepaid balance are separate purchase paths:

• Use a plan checkout to change the recurring subscription and entitlements.
• Add prepaid funds for explicitly metered services such as email validation.

The nitro_manage_billing MCP tool supports both paths without paying on the agent's behalf. Billing mutations require an account-scoped API key or an authenticated owner/admin handoff. The tool returns an approval URL when required and a purchase ID for verified status polling. Follow Payments for agents for MCP, CLI, and REST examples, or read Purchase lifecycle for the state and authority model.
