TL;DR
ListKit creates and configures domains and inboxes for you.
Each domain has 2 inboxes, capped at 25 emails/day per inbox.
DNS, warm-up, ramp-up, and inbox reputation are fully managed by ListKit.
You don’t need to touch technical settings or warm-up controls.
When you’d use this / Why it matters
If you’re on ListKit’s DFY (Done-For-You) cold email program, deliverability depends heavily on how domains and mailboxes are set up. This article explains exactly what ListKit handles behind the scenes so you know what to expect and what you don’t need to manage.
Domain and mailbox setup
ListKit creates and prepares all sending infrastructure for DFY campaigns.
2 inboxes are created per domain
Each inbox is fully set up inside ListKit’s sending tool
All required DNS records are configured for deliverability, including:
DKIM
DMARC
You do not need to configure DNS records manually. Everything follows cold email best practices.
Sending limits
To protect inbox health and sender reputation:
Each inbox has a hard limit of 25 emails per day
This limit is enforced automatically
Limits cannot be overridden
These caps are designed to maximize inbox placement and reduce spam risk.
Sending ramp-up process
All new inboxes follow a controlled ramp-up process.
Campaigns start at 1 email per inbox per day
Sending volume increases by 4 emails per day
Ramp-up continues until the inbox reaches 25 emails/day
This gradual increase builds trust with email providers and stabilizes deliverability.
Warm-up process
Warm-up is required and fully managed by ListKit.
Warm-up runs for a minimum of 7 days
Warm-up is never turned off
ListKit manages:
Warm-up enablement
Ongoing sending reputation
Inbox health monitoring
You do not control or adjust warm-up settings.
Email signature
Your email signature is automatically applied during setup
You can view or edit your signature later if needed
