Annual billing saves about 20%. Sending more than 1M emails per month? [Contact sales](/contact-us/) for custom volume. Sending more than 1M ## Multi-million per month is normal here. Our biggest senders are well past 1M, and the platform is sized for it. Online checkout stops at 1M to keep the cart simple. Past that, a 10-minute call lets us size IPs, sub-accounts, and support to your sending profile, then we get you running. [Talk to sales → ](/contact-us/?utm%5Fsource=outboundsmtp&utm%5Fmedium=pricing&utm%5Fcampaign=osmtp%5Fover%5F1m) Optional add-on ## Dedicated IPs for high-volume senders Once your sending volume justifies it, a dedicated IP gives you full control over your sending reputation. Yours alone, not shared with the wider relay pool. Available as an add-on, not bundled into any tier. - **Available at the 125K tier and above.** Lower-volume customers stay on the shared pool, which is the right call until volume justifies the spend. - **Multiple IPs at 500K and above.** Useful for sender segmentation (marketing vs transactional, brand vs region) where you want each stream on its own reputation. - **Regions: US (Oregon) or EU (Frankfurt).** Pick the geography closest to your sending profile. Add-on price $45 / month per IP, billed monthly [Add a dedicated IP → ](/contact-us/?utm%5Fsource=outboundsmtp&utm%5Fmedium=pricing&utm%5Fcampaign=osmtp%5Fdedicated%5Fip) Ordered through support so we can verify your sending profile fits a dedicated IP. Add-on for M365 / Workspace ## Relaying from Microsoft 365 or Google Workspace? The No Password Smart Host lets you point Microsoft 365 or Google Workspace at DuoCircle for outbound relay even where the platform does not allow username and password authentication for smart hosting. Authentication is gated by DKIM validation on the sending domain instead. - **Billed per sending domain.** Each authorized sending domain is a separate Smart Host subscription. Requires a paid Outbound SMTP plan alongside. - **Validated DKIM required** on the sending domain. Configure the domain in the portal Sender Domains and DKIM tool before activation. SPF is not required. - **Single IP target.** Designed for individual platforms or services that cannot support standard SMTP authentication. Not for distributing across many source IPs.
