The short answer

  • Instantly : Published cold-email sequencer pricing with warmup, if you need a rate card before a demo. From $47/mo
  • Smartlead : Unlimited mailbox sequencer with printed plans, without the agentic list-building pitch. From $39/mo
  • Mailreach : Dedicated warmup and inbox placement, not a full outbound agent. From $20/mo
  • Folderly : Inbox placement monitoring and deliverability testing without buying mailboxes from the same vendor. From $79/mo

Why people look past Mailscale

The vendor does not publish a rate card. The homepage tells you to get a custom plan on a call, so there is no self-serve pricing.

What we noted

  • No public rate card
  • Pricing is a sales call, not self-serve checkout
  • Shared mailbox infrastructure is a deliverability variable you do not control

Not the right fit for

  • Teams that need a published per-inbox rate before talking to sales
  • In-house recruiters who only need an ATS, not outbound email

Worth keeping in mind: The live homepage sells an autonomous outbound agent that writes 125 email variants and reroutes sends when inbox placement drops, on top of mailbox provisioning.

What each one does differently

Instantly

$47/mo Free trial MCP API

Why it comes up: Published cold-email sequencer pricing with warmup, if you need a rate card before a demo.

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.

Best for

  • Outbound recruiting teams sending at volume
  • Agencies running many sending accounts
  • Desks that need warmup plus a unibox

Smartlead

$39/mo Free trial MCP API

Why it comes up: Unlimited mailbox sequencer with printed plans, without the agentic list-building pitch.

Stands out: Unlimited mailboxes plus separate client workspaces, with a hosted MCP.

Watch out: Email only: there is no LinkedIn channel and no finder in the same login.

Best for

  • Agencies sending for multiple clients
  • Teams that need many mailboxes
  • Desks that want MCP on campaign infrastructure

Mailreach

$20/mo

Why it comes up: Dedicated warmup and inbox placement, not a full outbound agent.

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

  • Cold emailers warming Google Workspace or Microsoft inboxes
  • Agencies that want spam tests next to warmup, not warmup alone
  • Senders on a sequencer that does not include a strong warmup network

Folderly

$79/mo Free tier

Why it comes up: Inbox placement monitoring and deliverability testing without buying mailboxes from the same vendor.

Stands out: The product is placement and authentication (SPF, DKIM, DMARC, seed-list inbox tests), not a warmup bot and not a sequencer.

Watch out: Folderly does not send your campaigns. You still need Instantly, Smartlead, or Google Workspace as the actual mail server.

Best for

  • Outbound teams whose mail is landing in spam and need placement proof
  • RevOps watching DMARC and inbox placement across many domains
  • Agencies that want a deliverability report to show clients
