Inbox Radar Review: Pricing, Pros, Cons, and Alternatives (2026)
You're sending cold emails, doing everything right - SPF, DKIM, DMARC, conservative volume - and your Gmail placement is still tanking. You don't need another warm-up service. You need a diagnostic tool that tells you exactly where your emails are landing and why.
The email deliverability tools market hit $1.2B in 2024 and is projected to reach $2.41B by 2032, so there's no shortage of options claiming to solve this. Here's where Inbox Radar fits, where it falls short, and what we'd actually recommend depending on your situation.
30-Second Verdict
- Saleshandy users on a budget: Inbox Radar - cheapest path to placement monitoring inside Saleshandy
- Serious placement testing: GlockApps - strongest multi-region coverage and high test volume
- Warm-up + testing in one tool: MailReach - two problems, one subscription
- Bounces are the real problem: Fix the data before you diagnose placement
Inbox Radar Pricing Explained
Inbox Radar pricing gets confusing because people mix up three different things: standalone Inbox Radar plans, annual vs. monthly billing for those plans, and Saleshandy Outreach plans that include a small number of "Inbox Placement Tests" inside your sending subscription.
Here's the standalone tiering:
| Plan | Monthly | Annual (per mo) | Tests/Month |
|---|---|---|---|
| Free | $0 | $0 | 2 |
| Inbox Starter | $49/mo | $23/mo | 120 |
| Inbox Pro | $99/mo | $79/mo | 250 |
| Inbox Scale | $199/mo | - | 600 |
Then there are the Saleshandy outreach plans (sending plans) that bundle a tiny number of placement tests:
- Outreach Pro: $99/mo monthly or $69/mo annually - includes 1 Inbox Placement Test
- Outreach Scale: $199/mo monthly or $139/mo annually - includes 2 Inbox Placement Tests
These aren't standalone Inbox Radar subscriptions. They're limited placement checks tacked onto your outreach plan. If you need real testing volume, you'll want a dedicated Inbox Radar tier.
Key Features
Inbox Radar supports three test types: Recurring scheduled monitoring, Manual on-demand checks, and External tests from outside Saleshandy. Choosing Gmail, for example, sends to 19 seed recipients across providers.
Reports deliver inbox/spam/other/undelivered breakdowns by provider, SPF/DKIM/DMARC authentication checks, IP and domain blacklist status with delisting suggestions, and SpamAssassin scoring where negative scores mean extremely safe, 0-0.2 is safe, 2.1-5 is a warning, and 5+ means spam risk. You also get shareable public report links that require no login - handy for showing clients or teammates without forcing them into another dashboard.
The premium automation is the standout feature. It pauses email accounts or entire sequences when placement drops below your threshold. Saleshandy recommends a 60-190 second delay between test sends to mimic human patterns, which tells you they're thinking about this the right way.
Inbox Radar shows you where emails land. But if your bounce rate is above 3%, placement tools are treating symptoms, not the disease. Prospeo's 5-step email verification with catch-all handling and spam-trap removal delivers 98% accuracy - refreshed every 7 days so job changes don't silently wreck your domain.
Fix the data first. Placement follows.
Pros and Cons
Pros:
- Free entry at $0/mo with 2 tests, plus annual billing as low as $23/mo
- Clean, actionable reports with specific scores and authentication diagnostics - not vague letter grades
- Native Saleshandy integration means zero setup friction if you're already on the platform
- Premium automation that pauses sequences on placement drops is a genuine differentiator for protecting sender reputation
Cons:
- No warm-up included - purely diagnostic. Saleshandy points you to TrulyInbox for warm-up, which means another vendor
- Surfaces problems but doesn't fix them. One Reddit user reported 11-17% Gmail spam placement despite conservative sending and proper authentication - Inbox Radar showed the problem clearly, but the fix was entirely on them
- Pricing is easy to misread if you mix standalone plans with Outreach bundles
- No dedicated G2 or Capterra listing for Inbox Radar itself - you're relying on Saleshandy's G2 profile (4.6/5, 773 reviews) as a proxy, where reviewers consistently praise ease of use but flag warm-up limitations
- Seed list coverage is narrower than GlockApps
Inbox Radar vs. Alternatives
| Tool | Starting Price | Free Tier | Warm-Up | Best For |
|---|---|---|---|---|
| Inbox Radar | $23/mo (annual) | Yes (2 tests) | No | Saleshandy users who need integrated monitoring |
| GlockApps | $59/mo | Yes (2 tests) | No | Teams running lots of tests across regions |
| MailReach | $19.5/mailbox/mo | No | Yes | Anyone who wants warm-up and testing in one tool |
| Folderly | ~$64/mo (annual) | Yes (limited) | - | Agencies wanting an "unlimited testing" model |
GlockApps
GlockApps is the tool you pick when placement testing is your primary job. The Essential plan at $59/mo gives you 360 spam test credits - three times what Inbox Radar's $49/mo plan offers. Growth runs $99/mo and Enterprise $129/mo for teams needing even more volume. We've seen teams running tests across 20+ domains default to GlockApps because the multi-region seed coverage is simply broader, and when you're diagnosing email deliverability issues across different geographies, that coverage matters more than a slick dashboard.
MailReach
Here's the thing: managing separate warm-up and testing tools is annoying. That's MailReach's entire pitch. At $19.5/mailbox/mo, it bundles warm-up with spam testing credits (the all-in-one plan includes at least 20 spam test credits). The spam testing covers SPF/DKIM/DMARC checks, blacklist monitoring, and seed list rotation. For most teams under 10 mailboxes, this is the most practical choice - one bill, one dashboard, two problems solved.
Folderly
Unlimited tests. That's Folderly's pitch, and for agencies managing dozens of client domains, it's compelling. At around $64/mo annually, the unlimited model pays for itself quickly if you're testing more than 15-20 domains regularly. For a single-domain operation, skip it - you'll never use enough tests to justify the cost.
Who Should Use Inbox Radar
Use this if you're already on Saleshandy for outreach and want integrated placement monitoring without adding another vendor. The premium automation that pauses sequences on placement drops is something we haven't seen done as cleanly elsewhere.
Skip this if you need warm-up bundled, broad international seed coverage, or unlimited testing volume. GlockApps or MailReach will serve you better.
Let's be honest about something the deliverability tool market doesn't like to say out loud: most cold email deliverability problems aren't placement problems. They're data problems. If your bounce rate is above 3%, no amount of placement testing will save your sender reputation. Inbox Radar can tell you emails are landing in spam, but it can't tell you that 15% of your list is invalid and quietly destroying your domain. The consensus on r/coldemail threads backs this up - people chase placement fixes for weeks before realizing their list hygiene was the root cause all along.
Verify your contacts first. Prospeo's email verification runs a 5-step process with catch-all handling and spam-trap removal - 98% accuracy across 300M+ profiles, with a 7-day data refresh cycle that catches job changes before they become bounces. Then use a placement tool to monitor inbox rates downstream. That order matters.
If you want the deeper mechanics behind why bounces hurt you so fast, start with email bounce codes and then map it to email delivery vs. placement.
Teams spend $23-$199/mo diagnosing placement issues that bad data caused in the first place. Prospeo verifies emails at $0.01 each across 300M+ profiles - catching invalid addresses, spam traps, and honeypots before they ever touch your sending infrastructure.
Stop chasing spam folder fixes when your list is the problem.
FAQ
Is Inbox Radar free?
Yes - the free plan includes 2 placement tests per month with full reporting. Paid plans start at $23/mo on annual billing ($49/mo monthly), scaling up to 600 tests/mo on the Inbox Scale tier.
Does Inbox Radar include email warm-up?
No. It's purely diagnostic - it tests where emails land but doesn't improve placement directly. MailReach bundles both warm-up and placement testing from $19.5/mailbox/mo, making it the better fit if you need both.
What if bad contact data is causing my spam issues?
Placement testing won't help if bounces are wrecking your sender reputation. A bounce rate above 3% signals to ESPs that you're sending to unverified lists. Fix the data first, then monitor placement - that sequence saves you weeks of chasing the wrong problem.
How does Inbox Radar compare to GlockApps?
GlockApps offers stronger multi-region seed coverage and higher test volume (360 credits at $59/mo vs. 120 at $49/mo). Inbox Radar wins on Saleshandy integration and lower entry pricing ($23/mo annual). Choose GlockApps for dedicated deliverability work; choose Inbox Radar if you already live inside Saleshandy.
