What GlockApps does well
- The reference tool for inbox placement tests: send to a seed list and see where each provider filed the message, including Gmail, Outlook and corporate filters.
- DMARC analytics, uptime monitoring and IP reputation monitoring in the same subscription, so one tool covers the monitoring side of deliverability.
- A genuine free tier with 2 tests a month, and one-off credit packs from $16.99 for occasional checks.
- Free public checkers for SPF, DKIM, DMARC, MX and BIMI that are useful during inbox setup.
- Annual billing cuts 30 percent, and monthly plans can be cancelled month to month.
Where it falls short
- Monthly billing is expensive for a solo sender: $85 a month for 30 tests, or about $2.80 a test.
- Credit packs expire quickly (1 to 3 months), so unused tests are lost.
- API access and Google Postmaster integration start at Growth ($142 monthly), not Essential.
- Refund terms are not stated on the pricing page.
- It tells you where a message landed; it does not fix anything, and a seed-list test is a sample, not a guarantee of how your real list will be filtered.

What GlockApps is
GlockApps is a deliverability testing and monitoring suite. Its core product, Inbox Insight, is the seed-list placement test: you send one email to a set of GlockApps-controlled addresses at Gmail, Outlook, Yahoo and other providers, and it reports whether each copy landed in the inbox, promotions or spam, along with authentication results and content flags. Around that it bundles DMARC analytics, uptime monitors, IP reputation monitors, a DMARC-hardening product it calls DMARKOFF, and Google Postmaster Tools integration on the higher plans. It also publishes free SPF, DKIM, DMARC, MX and BIMI checkers.
Pricing explained
There are three paid bundles and a free tier. On monthly billing Essential is $85, Growth $142 and Enterprise $185; annual billing takes 30 percent off, to $59, $99 and $129 a month. The main difference between tiers is volume: 30, 90 or 150 spam tests a month, 50,000, 100,000 or one million DMARC messages, and more uptime and IP monitors. API access and Postmaster integration start at Growth.
For someone who only needs an occasional test, the free tier gives 2 tests a month and the credit packs cost $16.99 for 3 tests, $47.99 for 10 or $75.99 for 20, valid for one, two and three months. Per test that is $5.66, $4.80 and $3.80 against about $2.80 on Essential monthly, so packs suit occasional use and the subscription suits weekly testing.
Setup and how the tests fit a cold email workflow
Setup is trivial: create an account, copy the seed list, send a message from the inbox you want to test. The useful moments are right after a new inbox is set up, at the end of warmup before real volume, and any time reply rates fall on a domain. The DMARC analytics need your DMARC record to point its reports at GlockApps, which is a one-line DNS change.
What a placement test can and cannot tell you
A seed-list test shows how a specific message from a specific inbox was filtered at that moment. It is a strong signal for authentication problems and content flags, and a reasonable early warning for reputation, but it is a sample of a few dozen addresses, not your prospect list, and it fixes nothing on its own. Treat a bad result as a prompt to check DNS, warmup and list quality, not as a verdict.
Who it is for, and who should look elsewhere
Agencies and teams running many domains get the most from a subscription: repeatable tests, DMARC reporting across every client domain and IP monitors in one place. A solo sender with a handful of inboxes should use the free tier or a credit pack after setup and again when something looks wrong, rather than paying $85 a month. For DMARC reporting on its own, EasyDMARC starts at $35.99 a month for two domains.
Using GlockApps with PureMail
PureMail delivers inboxes with SPF, DKIM, DMARC and MX already set, so the first GlockApps test is a confirmation: send one campaign-style email from a new inbox to the seed list and check that the Gmail and Outlook copies land in the inbox and that all three authentication checks pass. Run it again at the end of warmup before you raise daily volume, and put the DMARC reports for your sending domains into GlockApps so you see authentication failures before a mailbox provider does.

GlockApps FAQ
How much does GlockApps cost?
As of September 2026 GlockApps has a free tier with 2 spam tests a month, then Essential at $85 a month ($59 on annual billing), Growth at $142 ($99 annual) and Enterprise at $185 ($129 annual). One-off credit packs cost $16.99 for 3 tests, $47.99 for 10 and $75.99 for 20.
What does a GlockApps spam test do?
You send one email to a list of seed addresses at Gmail, Outlook, Yahoo and other providers, and GlockApps reports where each copy landed: inbox, promotions, spam or missing. It also shows authentication results and content flags for that message.
Does GlockApps include DMARC monitoring?
Yes. Every plan includes DMARC analytics with a monthly message allowance: 10,000 on Free, 50,000 on Essential, 100,000 on Growth and one million on Enterprise, with overuse billed per 100,000 messages.
Is GlockApps worth it for cold email?
For agencies and anyone running dozens of domains, yes: regular placement tests catch a domain sliding into spam before the reply rate shows it. A solo sender with a few inboxes is usually better served by the free tier or a credit pack after setup and again if replies drop.
How do I test PureMail inboxes with GlockApps?
After PureMail delivers the inboxes, send one real campaign email from an inbox to the GlockApps seed list and check that Gmail and Outlook copies land in the inbox and that SPF, DKIM and DMARC pass. Repeat after warmup and whenever open or reply rates drop.
