Where the first month goes

Sending from brand-new mailboxes is how a startup lands in spam.

Nothing in a five-person team's week is worse spent than debugging email setup.

New mailboxes have no reputation

A mailbox that starts sending at full volume on day one looks nothing like a real sender, and the inbox providers notice.

Mailboxes set up one at a time

Every account across Google Workspace, Outlook or a custom provider is configured by hand when there is no automation.

Nobody to own email infrastructure

A small team can't staff a deliverability specialist, so the job lands on whoever last touched the DNS.

Your first weeks

From domain to campaign-ready, step by step.

Connect the domain, set up mailboxes, warm them for 2-3 weeks and export them to your sequencer.

“We connected our domain, warmed our mailboxes for three weeks and exported them to our sequencer without anyone on the team learning DNS.”
