Danish Lead Co.: Provisioning at agency speed, end to end
“InboxLee shipped our last cohort of mailboxes faster than my own team could’ve set up the DNS. Domains bought, records applied, mailboxes ready - zero hand-holding.”
The challenge
Running cold email at agency scale means every new client cohort is a fresh stack of domains, DNS records, mailboxes, and warm-up schedules to configure. Even a small mistake in SPF, DKIM, or DMARC can tank deliverability for the whole batch.
Frederik’s team needed a way to stand up new mailbox cohorts quickly without becoming part-time infrastructure engineers - and without compromising on deliverability or vendor compliance.
What InboxLee handles
InboxLee buys the domain on the cheapest registrar, applies SPF / DKIM / DMARC automatically, and provisions Google Workspace mailboxes through the official partner program. Warm-up days are tracked directly from the team’s sending tool API - InboxLee monitors, the sending tool warms.
Once a mailbox is live, it’s exported into Smartlead with one click. No CSV gymnastics, no copy-paste, no DNS work for Frederik’s team to babysit.
The result
Danish Lead Co. now runs 400 Google Workspace mailboxes through InboxLee - provisioned through the official partner program, with full vendor support behind every mailbox and zero DNS work for the team.
Mailbox cohorts ship in roughly the time it takes to grab a coffee. The team gets premium-grade infrastructure without the operational overhead.
Ship outbound that actually lands.
Your first mailbox is live in minutes. No credit card to start.
