The challenge

Boltline was paying $3.97/mailbox on Instantly''s done-for-you plan plus tier minimums, paid replacements when accounts got flagged, and an annual server fee tucked into the contract. Their effective cost was closer to $5.10/mailbox once everything was tallied — and replacements during bad weeks could add another $400–600 to a given month.

Why they chose Icemail

Flat $2.50/mailbox. No tiers. No replacement fees. No server surcharge. Same Google and Microsoft providers, same DNS automation, plus a unified inbox and exports that worked with the same sequencers they already used.

The solution

Boltline migrated 312 mailboxes to Icemail across two weekends, kept their existing Smartlead workflows untouched, and used the export tool to push everything live in their sequencer without manual re-entry. Workspaces preserved their existing per-client structure 1:1.

The results

Monthly infrastructure spend cut from $1,590 to $670 (–58%)
Saved ~$640/month previously spent on paid mailbox replacements
Deliverability held or improved on every client account
Migration completed in under 16 hours of total work

"We were quietly paying a tax on every burned mailbox. Icemail just… doesn''t charge it. It changed the unit economics of the agency." — Renee Okafor, Founder, Boltline Agency

What''s next: Consolidating two additional sub-brands onto Icemail and exploring whitelabel for a SaaS spinoff.
