Overview

What Warmup Inbox does

Warmup Inbox connects sending mailboxes to a network of real inboxes that exchange messages, open and reply to them, and monitor spam placement, DNS configuration, and blacklist status. It also offers cold-email sequences and lead-list verification.

Buying context

Fit and constraints

Best for
Outbound teams, marketers, recruiters, and agencies warming email inboxes and running deliverability-conscious outreach.
Relevant constraints
  • Warm-up does not guarantee inbox placement or campaign performance.
  • The product requires connecting an existing mailbox or SMTP-capable provider; mailbox or domain provisioning is not established.
  • Provider support and warm-up limits vary by plan.
  • Annual prices are billed as one 12-month payment.
  • Agency plans, volume discounts, multi-client workspaces, white-label reports, and consolidated billing require a quote.
  • Taxes are not stated on the reviewed official pricing page.
  • The official FAQ contains an older starting-price statement of $19 per inbox per month, while the current pricing page lists Basic at $15 per inbox per month monthly; this is an unresolved official-source conflict.
