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.
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 send through them. Same nitrosend platform, your deliverability domain, no double-pay.
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 your account settings. Your brand, not ours.
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. Every plan, including Free, includes full MCP access (Claude, ChatGPT, Cursor, Codex, Gemini) and REST API access. We don't gate integrations behind tiers.
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.
