How this compares
One subscription where the market sells three products
Deliverability tooling usually splits into placement testing, blacklist monitoring, and DMARC analytics, each priced separately. Here is the honest lay of the land.
| Approach | Typical price | What you get | The catch |
|---|---|---|---|
| Inboxes | $29 to $349/mo flat | Placement tests + 130+ blacklists + reputation + DMARC parsing, ranked fixes | Seed results are estimates; we say so on every report |
| Enterprise suites (Validity Everest, Litmus) | $500+/mo, often annual contracts | Deep analytics, certification programs, rendering QA | Sales-gated, priced for enterprises, most senders use a fraction |
| Credit-pack testers (GlockApps) | $59 to $129/mo + credits | Solid placement tests and DMARC analytics | Per-test math, raw results you still have to interpret |
| One-shot checkers (Mail-tester and similar) | No cost per check | A quick content and auth score | No real placement, no history, no monitoring, no fixes |
| Warmup tools | $19 to $149 per inbox/mo | Bot networks that fake engagement | Against provider policy and actively enforced since 2023; we do not do this |
If you need enterprise certification or rendering previews, the suites earn their price and we say so in our honest comparison of email deliverability tools. If you need to know where your email lands and what to fix, that is what these plans do.
Pricing questions
The fine print, in plain language
There is no free plan. The interactive placement board on the homepage is the hands-on taste of the product, and every plan is month-to-month unless you choose yearly, so trying Inboxes costs one month of Solo at 29 dollars. No credit card gymnastics, no sales call, cancel from your account anytime.
One email sent to your seed list and read across the panel counts as one test, whatever the result. Re-tests after fixes count as tests too, which is why every plan includes a healthy monthly allowance: Solo 25, Growth 100, Scale 300, Agency 1,000. Unused tests do not expire into credits; the allowance resets monthly.
Yes. Upgrades apply immediately with prorated billing, downgrades at the next cycle, and cancellation stops renewal while keeping access to the end of the paid period. Yearly plans work the same with a yearly cycle.
Neither, within plan limits. Each plan includes a set number of sending domains (1, 5, 15, or 50) and team members (1, 3, 10, or unlimited). If you are an agency juggling more, the Agency plan adds client workspaces and white-label PDF reports at 349 dollars per month.
Because deliverability is not a one-shot event. A single test tells you where you landed today; the value is testing, fixing, re-testing, and monitoring so it stays fixed. Credit packs push people to ration exactly the loop that makes the tool work, so we price flat instead.
