| Free plan | 2 Inbox Insight test credits/month, up to 10,000 DMARC messages/month, 5 uptime monitors. | A basic spam test available with no account required, covering authentication, content, and blacklist checks for a single message. |

| Setup time | Under an hour to run a first seed test; DMARC Analytics requires a DNS record change (pointing the RUA tag) that can take up to 24-48 hours to start receiving reports depending on receiver reporting schedules. | Minutes for on-demand testing: request an address, send a message, read the result. Configuring the automatic testing on the top plan takes longer, since outgoing mail from your senders has to be routed through the test. |
| Learning curve | Low for running a seed test and reading inbox/spam placement; moderate for interpreting DMARC aggregate data and spam-filter scoring without prior authentication knowledge. | Low. The findings are written for marketers rather than engineers, and the AI consultant explains anything unfamiliar. The conceptual point a buyer must grasp is that a good test score is not proof your list received the mail. |

Strengths and limitations
GlockApps
Strengths
- Broad seed-list panel (70+ addresses across Gmail, Outlook, Yahoo, corporate) gives a credible cross-provider placement read for the price.
- DMARC Analytics is a full-featured report parser on its own, competitive with dedicated DMARC-only tools, and the free tier's 10,000 messages/month is genuinely usable for small domains.
- Blacklist and DNS-record monitoring catch infrastructure problems (a broken DKIM key, a new blacklisting) before they show up as a placement drop.
- Gmail tab prediction addresses a specific, common blind spot that plain inbox/spam scoring misses.
Limitations
- No native warm-up or sending capability; a separate G-Lock-affiliated product (WarmupIP) handles warming under its own brand, so buyers expecting one bundled subscription for testing and warming will need a second tool and a second bill.
- Seed tests measure a fixed panel of test inboxes, not your actual recipient list; results are a strong proxy, not proof of how any individual subscriber's mailbox will filter a message.
- Interface and reporting design read as dated next to newer entrants, functional but not polished.
- Free tier's 2 test credits are too thin to evaluate the product's core value without upgrading.
MailGenius
Strengths
- A genuinely free, no-account spam test that has been the entry point for a large number of senders and is still a complete diagnostic for occasional use.
- Itemized findings with plain-language reasons rather than an opaque score, which makes the output actionable for a marketer.
- AI copy analysis and rewriting sits alongside the technical checks, which is unusual and reflects the fact that filters read content as well as headers.
- Automatic testing of every outgoing message on the top plan turns testing from a discipline into infrastructure.
Limitations
- No documented seed panel composition or provider-by-provider placement statistics, so it produces a diagnosis rather than publishable placement evidence.
- No DMARC aggregate report ingestion, so it cannot tell you who else sends as your domain or drive a p=reject deployment.
- No warming or reputation building at all, so a cold sending domain will keep failing tests no matter how many you run.
- No rendering or dark mode preview testing, which Unspam bundles at a lower price.
Pricing compared
GlockApps
Tiered monthly or annual subscription metered on Inbox Insight test credits and DMARC message volume, with a free tier and per-tier overage pricing above the included message allowance.
- Free$0
- Essential$59
- Growth$99
- Enterprise$129
GlockApps is priced fairly for what it is: a diagnostics and monitoring subscription, not a fix. $59-99/month buying seed testing across 70+ addresses, full DMARC reporting, and blacklist monitoring is cheap relative to hiring a consultant to do the same work manually, and cheaper than most warm-up suites that bundle a thinner placement-testing feature. The catch is that none of it repairs anything: a team that finds a domain in spam through GlockApps still needs a separate warmer, a DMARC policy change, or a blacklist delisting request to act on the finding, so budget it as the measurement layer, not the whole deliverability line item.
MailGenius
Freemium, with a free no-account spam test and three published monthly subscription tiers separated by test volume and monitoring capability.
- Free spam test$0
- Beginner$23
- Genius$39
- Automatic Testing and Domain Monitoring$79
At $39 for unlimited testing with AI copy analysis, MailGenius is fairly priced against the specialist placement platforms, and the free test undercuts the entire category for occasional use. The $79 tier is where the value judgement gets interesting: automatic testing of every outgoing message and unlimited-domain blacklist monitoring is genuinely a different product from an on-demand checker, and no other tool at this price watches continuously in that way. What you are not buying is a documented seed panel with provider-by-provider placement statistics, which is what GlockApps sells, or rendering testing, which is what Unspam bundles. Buy MailGenius for the diagnostic and the copy layer; buy elsewhere if you need publishable placement evidence.
Editorial verdict on each
GlockApps
Best ValueGlockApps is the sharpest diagnostics-and-monitoring buy in the category for teams that already have a sender and just need to know, with evidence, where mail is landing and why. Seed testing across 70+ addresses, full DMARC reporting, and blacklist monitoring at $59-99/month undercut most warm-up suites' bundled testing features while going deeper on each one. The tradeoff is real: nothing in GlockApps fixes what it finds, so a team expecting one subscription to both diagnose and repair deliverability will end up buying a second tool anyway. Budget it as the measurement layer of a deliverability stack, not the whole stack.
Read the full GlockApps profileMailGenius
MailGenius is the deliverability tool most people have already used without paying for it, and the free no-account test remains a complete diagnostic for occasional senders. The paid product is worth considering for two reasons: the AI copy layer, which treats content as a deliverability variable rather than a marketing one, and the $79 plan's automatic testing of every outgoing message with unlimited-domain blacklist alerting, which no comparable tool offers at that price. Against that, there is no documented seed panel, no DMARC report monitoring, no rendering testing, and no warming, and the vendor is a small owner-operated business attached to a consultancy that will keep offering to sell you help. Buy it if you want to know why a message is likely to be filtered and want the answer in plain language. Do not buy it as a fix for a cold sending domain, because diagnosis is the whole product.
