Every plan is listed as starting from $49/month with volume-based pricing, so your real cost depends on how much warm-up you need and is not shown up front. Placement test allowances are confirmed with the Warmy team rather than published.
What we noted
Not the right fit for
Worth keeping in mind: Warmy lets you pick a B2B network of Workspace and Microsoft 365 mailboxes, which matters for recruiters emailing hiring managers at company domains, where many warm-up tools mix in consumer inboxes. It also pairs warm-up with a monthly rotating seed list and an AI co-pilot that explains what to fix.

$29/mo 7 day free trial MCP API
Why it comes up: WarmySender is another warm-up tool, useful to compare if you want per-mailbox pricing instead of volume-based plans.
Stands out: The agent integration is unusually deep and unusually guarded: 90 MCP tools reach campaigns on four channels, the unified inbox, lead search and verification, yet an agent can never send a message itself or raise a cap, because every action goes through the same scheduler as the web app. Recruiters also get something sales tools rarely offer, MCP tools that draft, publish and close LinkedIn Recruiter job postings and list applicants.
Watch out: The cheapest prices need commitment: the headline month to month Pro rate is $29, and the low per month figures come from paying a year ($156.60) or three years ($313.20) up front. LinkedIn, WhatsApp and Instagram are each $12 per connected account per month on top, so a multichannel desk adds up. Automating LinkedIn and Instagram from any tool carries account restriction risk even with WarmySender's ramps and caps, and ChatGPT only gets a reduced set of MCP tools.

$20/mo
Why it comes up: MailReach also pairs warm-up with spam tests and suits teams comparing warm-up networks.
Stands out: Warmup plus spam tests and blacklist checks in one warmup-first product, a step up from a $15 warmup-only bot.
Watch out: Mailreach does not host your sequences. Instantly and Smartlead already ship warmup, so a separate $20 seat is extra unless you send from Google or Outlook directly.
Best for
$37.60/mo Free trial MCP API
Why it comes up: Instantly bundles warm-up with its cold email sequencer, so teams already sending there may not need a separate warm-up tool.
Stands out: Warmup, unibox, and volume send with hosted MCP and a public API, plus an AI Recruiting Agent that finds candidates from a job link and emails them.
Watch out: Deliverability still depends on your domains and inboxes, not the tool alone.
