FREQUENTLY ASKED

What questions do we hear
about Outbound Automation often?

Outbound automation is the discipline of running cold outreach as a system instead of a headcount problem.

An SDR team manually researches, writes, and sends, capped by hours in a week.

A lead-gen agency hands you a list and a generic sequence.

We build a managed engine where signals trigger sends, AI personalizes copy at the prospect level, multi-channel orchestration happens across email, LinkedIn, and voice, and a human reviews every play before it ships.

We never send from your primary domain. We set up secondary sending domains that redirect to yours, then warm them up across a network of mailboxes. Whatever happens to those domains stays isolated, and your main domain stays safe. Because we run a pool of mailboxes per client, we can scale outbound volume without spiking spam flags.

Every prospect runs through enrichment and signal research before a single line gets written, so the message references something real about that account: a recent funding round, a hiring trigger, a competitor stack, a leadership change. AI drafts the personalization layer, and a human reviews copy before it goes live. The goal is a message that reads as if you'd written it yourself after twenty minutes of research.

Yes. Both. Before any send, we share the ICP definition, targeting filters, the actual prospect list, and every email and LinkedIn sequence. Nothing ships without your sign-off. Same applies to ongoing changes when we test new sequences or expand a persona.

We tag every reply by sentiment (positive, objection, unsubscribe) and route it into your CRM within minutes. Positive replies go to your SDRs or AEs to take from "yes, I'm interested" through to a booked meeting. We handle objections and unsubscribes on our side so your team only sees the conversations worth their time.

Two weeks from contract to first send. End of month 2 is when reply rates and meetings find their rhythm. For medium volume campaigns of 30k emails/month, expect 15-30 first-time appointments per month. For high volume campaigns of 100k emails/month & companies with good brand presence in that geo can expect 70+ meetings.

Two weeks from contract to first send. Week 1 covers ICP alignment, account mapping, messaging, tool setup, and infrastructure provisioning. Week 2 is domain warmup, sequence build, list load, and first send.

End of month 2 is when reply rates and meetings find their rhythm. Month 3 is when we know what's working, kill what isn't, and double down.

Fixed monthly retainer, starting at $2,500/month and scaling with scope. Most engagements land between $2,500 and $6,000/month depending on email volume, channel mix, geos, and whether CRM/RevOps work is included.

We don't do pure outcome-based pricing because infrastructure, list building, and messaging cost the same regardless of meetings booked, and outcome-only models tend to push agencies toward shortcuts that wreck your domain. We do stand behind the outcomes we forecast in the proposal; it's just not the billing mechanism.
