Delivery proof, via a verifiable hash chain.
For every send, an audit hash chain entry is recorded — an immutable, independently verifiable evidence chain for audits, customer disputes or internal review. Open verification, no tamper window.
There are two places we refuse to write marketing copy: delivery rate and support time. These live in numbers, not text. Our numbers are independently verifiable.
For every send, an audit hash chain entry is recorded — an immutable, independently verifiable evidence chain for audits, customer disputes or internal review. Open verification, no tamper window.
Our Enterprise customers’ median first-response time is 11 minutes. When you write at midnight, the reply comes — not from a translator, but from an engineer authorized to solve the problem.
When monthly uptime falls below what’s committed, the difference comes back to you as a refund. Automatic, to your account, no petition. An additional one-month credit is also granted.
Your past sending records, recipient lists and campaign data export with one click. Access stays open for 12 months even after the contract ends. The format is open standards.
Our monthly delivery reports, uptime statistics and support response times are public. When we don’t keep our word, you’ll notice — and see it.
