Key Features for Success

Deliverability First

SPF/DKIM/DMARC, proper warm-up, and strict pacing to protect reputation.

Smart Redundancy

3 inboxes per domain with 1:1 active/standby redundancy to keep placement strong.

Verified Data & Sequences

Clean, verified contacts + a baseline 3-email sequence to start conversations.

Dedicated Infrastructure

We build isolated domains and inboxes strictly for your campaigns. No shared resources. If we part ways, the assets can be transferred to you.

Inbox Management

We monitor inbox health, handle replies routing, and keep campaigns organized so nothing slips. As volume grows, the system stays clean, controlled, and scalable.

Provider Mix

We set up the right provider mix (Google Workspace and Microsoft 365) to strengthen placement and reduce risk. This keeps sending stable and protects your deliverability as you scale.

Got Questions? We’ve Got Answers.

Who is this for?
Best for businesses with a broad national or global audience (TAM of 50k+ contacts). If your market is tiny, this engine is too powerful for you.
70 / 100 / 150 active inboxes. Each plan includes a 1:1 rotation (standby), so total inboxes are double (e.g., 70 active = 140 total).
DIY: you write the emails. Managed Infra + Data / Inbox Management: we write the sequences; you approve before sending.
DIY / Managed Infra + Data: your team handles replies and bookings. Inbox Management: we qualify replies and book calls; you close.
We do not send before day 14. Days 0–14 are warm-up only.
Day 15–16 ≈ 1 send per inbox per day, day 17–18 ≈ 3–5, day 19–21 ≈ 8–10, day 22+ ≈ 12–15 (adjusted by health and placement).
We run a mix of Google Workspace and Microsoft 365 for variation. Provider matching (for example, Microsoft → Microsoft) can improve inbox placement and reduce fingerprint risk.
Typically 3 inboxes per domain. This balances volume and domain reputation
Included. Mailboxes and domains needed for your chosen plan (70/100/150 with 1:1 rotation) are covered in the package price.
Yes. Additional inboxes are $6 each/month and additional domains are $15 each/year. We usually add inboxes in active + rotation pairs to protect deliverability.
We don’t take on businesses with services under $10,000. Below that, unit economics are better with DIY using our tutorials or the Setup + Health (DIY) plan.
Targeted, relevant B2B outreach with a clear opt-out is generally permitted. We honour opt-outs immediately and suppress globally for your campaigns.
Verified data from reputable sources, filtered by role/title, firmographics, regions, and exclusions. We dedupe against your CRM where possible.
We engineer for inbox placement and qualified replies. Meeting volume depends on ICP fit, offer strength, and your sales follow-up. No guaranteed revenue.
DIY: monthly health summary. Managed/Inbox Management: weekly snapshot on volume, replies, meetings booked, and next actions.
Yes. Calendar links, routing rules, and light CRM handover are supported. Full CRM/dashboard handover is available as an add-on.
Monthly retainer with a 30-day notice period unless otherwise agreed in the SOW.
ICP, offer proof, calendar/CRM preferences, copy approval (or your draft if DIY), and a closer ready to take calls.
