What a reply means here

Total replies as EmailBison counts them, with out of office and auto-responders included. Both of us can check that number in the same dashboard.

Committed vs targeted

The 200,000 emails are committed. The 2% is the target. The reply figure is those two multiplied, so it moves with the rate.

One Stripe invoice, paid upfront. Covers domains, mailboxes, warmup, sending, inbox placement testing and the EmailBison account. There is no margin in it.

Separately: 20% of revenue above $5,000, per your offer on the call. That needs a baseline, an attribution window and a tracking mechanism agreed in writing before it can pay out. Phase 1 builds the tracking.

What 200,000 emails takes

One domain carries 25 inboxes. Each inbox safely sends 5 cold emails a day. So one domain is 125 emails a day, and volume is a quantity of domains.

Emails per day
14
Days of warmup
Of the 43 domains, 29 carry the daily volume and 14 are spare. Domains get flagged and burn out mid-campaign, so the spares warm alongside the rest and swap in without the send rate dropping.

Warmup takes 14 days before a domain can carry cold volume, and that window cannot be compressed. It is why sending starts in week 4 rather than week 1.

The split

Me

  • Register and configure 43 domains, DNS and authentication
  • Provision and warm 1,075 mailboxes
  • Run the EmailBison account, sequences and daily send
  • Monitor deliverability and rotate burnt domains out
  • Inbox placement testing on a schedule
  • Reply handling on the sending side
  • Weekly numbers: sent, delivered, reply rate

You

  • 10,000 rows of the sending list, before the invoice
  • The work-email segment of your 6M, as an export
  • Your copy, and approval on any change to it
  • Trial signup flow live and instrumented
  • Trial and paid conversion data back to us
  • Agash as the single technical contact
  • Approvals inside 24 hours
The 10,000 row sample comes first and costs nothing. I verify it and read the bounce profile before buying a single domain. A stale list burns the infrastructure in week one, and that money does not come back. The invoice can go out in parallel so nothing waits, but no domains are bought until the sample clears.

Phase 1 is work emails only. Personal inboxes are a different deliverability problem and they wait. Copy stays yours and unchanged, so the test measures one thing.

Timeline

Week 1Sample verified. Domains registered, DNS and authentication configured, mailboxes created. Data segmented, copy loaded, tracking agreed with Agash.
Weeks 2 to 3Warmup across the full pool. No cold sending.
Week 4Sending starts and ramps toward 3,600 a day. First inbox placement test.
Week 5Checkpoint at roughly 30,000 sent. 30,000 sends is enough to know whether 2% holds.
Weeks 5 to 11Held at rate to 200,000. Burnt domains rotated out, replies handled, trial data reconciled weekly.
If the rate is under target at the week 5 checkpoint, we stop there. The rest of the budget goes into the list, the copy or the segment instead of another 170,000 emails nobody is answering.
