Infrastructure that scales per client.
Per-client workspaces, free migration concierge, and the same $2.50/mailbox/month price at 4 mailboxes or 4,000. Built for agencies who ship cohorts, not for solo founders who ship campaigns.
Three things break at agency scale.
A new cohort every week
Each new client = a fresh stack of domains, DNS records, mailboxes, and warmup schedules to set up. Manually. While the existing 14 cohorts also need attention.
Switching cost from your current provider
You looked at Inboxlee six months ago and the math worked, but moving 200+ live mailboxes felt like a month of downtime. So you stayed.
White-label without a white-label tier
Your existing provider shows their brand in every credential email and dashboard. You wanted client-safe surfaces. They charge enterprise pricing for it.
Three things that just work for agencies.
One workspace per client
Every client gets their own scoped workspace. Domains, mailboxes, invoices, blacklist monitoring all isolated. Switch contexts with a dropdown - no logging out.
Free migration concierge above 25 mailboxes
Move existing client mailboxes from any provider with no downtime. We do the DNS dance, you do the campaign launch. Most cohorts switch inside one business day.
Volume that scales with you
Flat $2.50/mailbox/month with no per-seat minimums. 400 mailboxes costs the same per unit as 4 - the math gets better the more you ship, not worse.
Danish Lead Co. ships 400 mailboxes through Inboxlee.
Frederik Jakobsen runs a Copenhagen-based B2B lead-gen agency. Every new client cohort meant rebuilding the same DNS-and-tenant stack manually. Inboxlee handles every layer of provisioning so his team focuses on the cold outbound, not the infrastructure.
“Inboxlee shipped our last cohort of mailboxes faster than my own team could have set up the DNS. Domains bought, records applied, mailboxes ready - zero hand-holding.”
