The lead-gen agency that 10×'d its sending fleet

Snapshot: Pipeline Forge · 34 clients · Austin, TX · scaled from 48 to 520 mailboxes on Icemail

The challenge

Pipeline Forge was growing faster than its infrastructure could keep up. Every new client meant manually buying domains, creating mailboxes, configuring DNS, and exporting to a sequencer — a process that ate 6 hours per client and didn''t scale. Worse, inconsistent DNS setup meant deliverability varied wildly from client to client, and replacing burned mailboxes was a constant, costly fire drill that cost the team roughly 9 hours a week.

Why they chose Icemail

They needed infrastructure that scaled linearly with clients without scaling the manual work — and pricing that protected their margins. Icemail''s flat $2.50/mailbox, bulk provisioning, and one-click export checked every box.

The solution

The team moved to bulk mailbox creation with AI-powered autofill, set up a separate workspace per client to keep accounts isolated, and let Icemail handle SPF, DKIM and DMARC automatically on every domain. One-click export pushed each client''s mailboxes straight into Smartlead and Instantly. Unlimited free replacements turned the old fire drill into a non-event.

The results

  • Scaled from 48 to 520+ active mailboxes in 7 months
  • Cut per-client setup time from 6 hours to 18 minutes
  • 31% improvement in average inbox placement across clients
  • Saved $4,800/month versus their previous provider

"We onboarded more clients in Q2 than in all of last year, and our ops headcount didn''t budge. Icemail is the only reason that math worked." — Devon Marsh, Head of Operations, Pipeline Forge

What''s next: Expanding into Microsoft mailboxes for enterprise prospects and piloting the whitelabel program for two of their largest clients.
