InboxEagle : InboxEagle is another deliverability option to compare if you want a different take on placement monitoring. From $39/mo

Why people look past Unspam

The API, MCP server, DMARC monitoring and scheduled tests all need the paid Custom plan, and the free plan keeps results for only 14 days. It tests and diagnoses emails but does not warm up mailboxes or send campaigns.

What we noted

API and MCP only on paid plan
Free results kept 14 days
No warmup or sending

Not the right fit for

Teams that need mailbox warmup
High volume senders wanting a flat unlimited plan
Anyone who needs results kept long term on a free account

Worth keeping in mind: Unspam combines a spam score, seed list placement test, 50+ client previews and an AI assistant that explains fixes, and the free plan already includes 21 tests a month plus the AI assistant. Its pay per test Custom plan starts at $5 a month, far below the flat monthly fees of most placement testers.

What each one does differently

Mailreach

$20/mo

Why it comes up: MailReach adds mailbox warmup alongside spam testing, which Unspam does not do.

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: Folderly suits teams that want ongoing deliverability management rather than per test checks.

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

InboxEagle

$39/mo

Why it comes up: InboxEagle is another deliverability option to compare if you want a different take on placement monitoring.

Stands out: The $39/mo Email Deliverability SKU is flat regardless of list size, and bundles Google Postmaster, Klaviyo campaign sync, SPF/DKIM/DMARC alerts, and an AI agent that opens incidents when placement breaks.

Watch out: Ten seeds are included. Extra seed-list panels start at $99/mo for 100 seeds. DMARC aggregate processing and Audience Selection are separate SKUs. Consulting retainers start at $499/mo.

Best for

Klaviyo senders who want inbox placement and DNS alerts without a consultant
Agencies watching several brands from one command center
Teams that need seed-list folder movement beyond the included 10 inboxes
