Outbound email infrastructure, run properly.
Managed sending estates for cold outbound at scale — isolated from your primary domain, monitored continuously, integrated into your pipeline.
The estate, not just the sequences.
Dedicated sending domains isolated from your primary, so campaign volume never risks your core deliverability.
Sized to your volume with realistic per-mailbox limits and rotation baked in.
Reputation blast-radius is contained. A single burned mailbox does not take your team's inbox with it.
The technical, in plain language.
Deliverability is won in the infrastructure. Copy matters, but a beautiful sequence sent from a rotting estate lands in Promotions.
| Lookalike domain architecture | Every outbound campaign runs from dedicated lookalike domains. Your primary domain is never used for cold volume, so reputation risk cannot bleed into internal email, customer email or transactional mail. |
| SPF | Sender Policy Framework — a DNS record that lists which servers are allowed to send on behalf of a domain. Configured per lookalike, kept under the 10-lookup limit, monitored for drift. |
| DKIM | DomainKeys Identified Mail — a cryptographic signature added to every outbound message so receiving servers can verify the sender wasn't spoofed. Keys rotated on a schedule, alignment checked in reporting. |
| DMARC | The policy that tells receivers what to do when SPF or DKIM fail. Set to a monitored policy per estate with aggregate reporting so we see abuse and misconfiguration early. |
| Warmup protocol (~3 weeks) | Each new mailbox ramps against a known-good inbox pool with realistic reply behaviour. Volume climbs on a curve, not a step, so provider trust models score us as human traffic. |
| Per-mailbox volume discipline | Hard daily caps per mailbox — well under what platforms advertise as 'safe'. Volume comes from more mailboxes, not from pushing any single mailbox to its limit. |
| Rotation and cool-downs | Mailboxes rotate through campaigns and take enforced cool-down periods. A single burned mailbox is contained; the estate keeps sending. |
| Continuous monitoring | Seed inbox placement checks, blacklist watch, sender score tracking, bounce rate alerts. When something drifts, we know before you do. |

Who this is for — and who it's not.
- You send meaningful outbound volume and can't afford to burn your primary domain.
- You want deliverability run by people, not left to the sequencer's default settings.
- You need a single reply pipeline that feeds your CRM and the reply agent.
- You want a shared IP burst-and-hope service — that's how domains get blacklisted.
- You want to send from your primary domain with no separation.
- You expect infrastructure alone to fix a bad list or bad copy — it won't.
One pipeline, not two.
Reply flow feeds the Reply Agent and your CRM, unifying email and call-generated demand in a single view. No exports, no duplicated leads, no missed replies.
The honest FAQ.
No. That's the point. All outbound leaves from lookalike domains that are structurally isolated from your primary.
Volume divided by a safe daily cap per mailbox. We size the estate to your plan, not to what a platform will let you push.
Rotation, cool-down, and replacement lookalikes. Impact is contained; the campaign keeps running from clean estates.
You do. All lookalikes are registered in your name; if we part ways, they go with you.
