Three tiers are published. Pay-As-You-Go starts at EUR 0.032 per verification with message costs billed separately and no minimum commitment. Startup is EUR 360 / month and adds custom Sender ID, Slack support, advanced anti-fraud, and 6-month data history. Enterprise is custom priced with committed-volume discounts, a 99.95% SLA, dedicated support, post-payment terms, and unlimited data history. Volume discounts apply automatically at higher commitment levels, and an annual subscription includes a 10% discount. Message rates vary by country and channel (SMS, WhatsApp, RCS, Telegram, Viber) - for example a USD SMS is about EUR 0.0043. notes: >- Figures reflect the Prelude pricing page as of 2026-07-11 and are in EUR. Per-message carrier rates are pass-through and country/channel-specific; verify current numbers on prelude.so/pricing.
