Bulk sending, instrumented
Built for lists your business is actually accountable for.
- Consent you can produce on demand
- Every subscriber carries where they signed up, when, and from which address. When a mailbox provider forwards a complaint, that evidence either exists or it does not — it cannot be reconstructed afterwards.
- It stops before the provider does
- Bounce and complaint rates are checked on every batch against the thresholds that trigger suspension — 5% and 0.3% — not once when the campaign starts. A spike halfway through a send halts the rest of it.
- Open rates that count people
- Apple Mail Privacy Protection loads the tracking pixel whether or not anyone reads the message. Those fetches are separated out, so the number you report is the number that happened.
Gmail and Yahoo require SPF, DKIM, DMARC and one-click unsubscribe from anyone sending more than 5,000 messages a day. Nothing sends from a domain until all of them resolve.
