How teams ship outbound that actually lands.

Domains, mailboxes, authentication, and warm-up tracking, provisioned through the official Google and Microsoft partner programs. Here is how a real team runs it.

Featured case study

We shipped our last cohort of mailboxes faster than my own team could set up the DNS.

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.
