Snapshot: Carbon Talent · tech recruiting · London, UK · 140 mailboxes
The challenge
Carbon Talent runs outbound on two fronts: sourcing engineers for client roles, and winning new client mandates from heads of talent. Mixing both motions on the same domains was tanking reply rates — candidate-sourcing volume was getting their BD emails flagged, and a single bad week of deliverability could cost them a five-figure placement fee.
Why they chose Icemail
Per-motion domain isolation, predictable per-mailbox pricing, and unified reply management across teams made Icemail the obvious fit. Free replacements meant they could lean into volume without worrying about losing a domain mid-campaign.
The solution
Carbon Talent split their sending into two isolated workspaces — 90 mailboxes for candidate sourcing, 50 for client BD — each on their own domain pool with independent reputation. Both teams work out of a single unified inbox with tagging, so a sourcer never accidentally replies from a BD mailbox (or vice versa).
The results
- 2.4× more candidate replies per week
- Client BD reply rate stabilized at 7.8% (up from a volatile 2–5%)
- Placed 11 senior roles attributable to the new outbound motion in 6 months
- Zero domain blacklist incidents post-migration
"Our recruiters and our BD people finally stopped fighting over the same inbox reputation. Both numbers went up." — Hannah Boateng, Managing Director, Carbon Talent
What''s next: Adding a third workspace for a new executive-search practice launching next quarter.
