Pure utility pricing. Store unlimited contacts, pay only for what you send, and get engineers rather than support scripts.
Legacy platforms charge a storage tax: every contact you upload costs money whether you email them or not, and growth is capped by expensive overages. Our model is pure utility. You store unlimited contacts, host 10M+ contacts for free, and pay only for the emails you actually send. That removes the incentive to cut your list to save money, and it makes the cost of a campaign predictable before you send it.
The relay runs on our own hardware and IP ranges, with dedicated clean IPs for high-volume senders rather than pools shared with unknown senders. Deliverability is handled by forensic, human-led review of raw logs, not automated algorithms, and you get direct access to network engineers when something needs fixing. For what that looks like in practice, see how we diagnose email delivery problems.
The table below is the same comparison we publish on our homepage.
A relay is only as good as the reputation of the traffic on it. We help you keep it clean: throttling matched to each mailbox provider's limits, warm-up when you add volume or IPs, and monitoring of the signals that providers actually use. Two of those signals decide most placement outcomes: your spam complaint rate and your bounce rate. Since 2024 the major providers also enforce explicit rules for anyone sending 5,000 or more messages a day; our guides to Gmail's sender requirements and Microsoft's bulk sender requirements set out what the platform needs to satisfy on your behalf.
