Perfect leads get wasted without mailboxes built for outbound
Domain health, authentication, warm-up and sending limits are managed alongside the cadence rather than bolted on afterwards. Volume is capped by what the inbox will accept.
How sending is protected
01
Authenticate first
SPF, DKIM and DMARC are verified before a single message is queued, per sending domain.
02
Warm up in sequence
New mailboxes ramp over three weeks against real engagement, not synthetic volume.
03
Cap and pause
Sending is capped per mailbox and paused automatically when bounce or complaint rates drift.
Limits and controls
Caps are set per mailbox and per domain, and the cadence respects them. If a domain degrades, sending pauses before reputation is lost.
per mailbox
Daily send caps set per mailbox, with the cadence queueing rather than overrunning them.
suppression
Global suppression across the workspace, so two reps never hit the same contact.
verification
Addresses re-verified before send, not only at enrichment time.
consent
Unsubscribe and objection handling recorded against the contact and honoured across all channels.
