On Eden, dials booked more meetings than 41,150 emails
The channel comparison buried in Christian's 12 system list is the one number worth checking against your own account.
Christian published a list of 12 systems he says a GTM engineer must build, and the number most senders will argue about is the last one. On Eden, he writes, 41,150 emails booked 20 meetings and 32,577 dials booked 33. That is roughly a 20% smaller volume on the phone returning 65% more meetings.
The system he attaches it to is email and dialer sync. Same list into the sequencer and a parallel dialer, a blocklist for anyone already in an active email conversation, and every positive email reply called the same day. The point is not that dialing beats sending, it is that the two run off one list with rules about who gets touched where.
This is one client and one list. Eden Studio has shown up here earlier, and Christian says its owned TAM map ran to 69,204 accounts, so the email side is not a small or careless test. Still, a single account's channel split is a prompt to check your own cost per meeting, not a finding.
The other numbers in the post
Re-engagement is the cheapest claim to copy. Christian says pulling the last three to five campaign lists, re-running the enrichment waterfall, filtering out anyone who booked and re-targeting with a new angle produced an 11.75% reply rate on 1,532 ghosted prospects. His stated reason is churn in the data, 30 to 50% of contacts on a six month old list have moved jobs or changed details.
On infrastructure, he describes an inbox rotation dashboard that flagged 121 domains for rotation in one view, with a hard rule that every domain holds a 1%+ reply rate or gets replaced.
There is also an ESP router, which pulls each contact's email provider and splits the list into Google, Microsoft and security gateway. Gateway contacts, the ones sitting behind filters like Barracuda and Proofpoint, go to the phone instead. That is the same argument as the dialer number, arrived at from the deliverability side.
On testing, he recommends launching 15 to 30 variants at once with 1,000 sends each before judging any of them, and killing losers after two weeks.
Christian says all 12 run inside the systems behind $70M+ in pipeline for his clients.
On Eden, 41,150 emails booked 20 meetings and 32,577 dials booked 33.
The same campaign can land anywhere from 25 to 10,000 contacts per lead depending on the offer.
