GlockApps: cost, fit and limits
GlockApps is an email deliverability testing service that runs inbox placement and spam tests, DMARC, SPF and DKIM checks, and blocklist and IP reputation monitoring for senders, with API and MCP options listed on the vendor's pricing page.
What to know first
GlockApps publishes four tiers: Free at $0, Essential at $59 a month, Growth at $99 and Enterprise at $129, each also sold as an annual total. Allowances are counted in spam test credits, DMARC messages and monitors rather than seats. The copyright line names Deluxe Custom Apps LLC, and the pages opened state no trial length or data terms. The annual totals equal twelve monthly payments.

Who GlockApps is best for
Marketers testing a campaign before sending
Spam test credits show where a message is likely to land across Gmail, Outlook and Yahoo, and content analysis flags problems before the list receives it.
Small senders on a tight budget
The Free plan includes 2 spam test credits and 10,000 DMARC messages, and Essential at $59 a month covers 360 credits, enough to test regularly without a custom quote.
Teams watching domain authentication
A DMARC analyzer and digest sit beside SPF and DKIM checks, and Growth raises DMARC volume to 1,200,000 messages a month.

What GlockApps does
- Inbox placement testing
- A test shows where a campaign is likely to land across Gmail, Outlook and Yahoo before sending. Each test consumes a spam test credit from the plan.
- DMARC analyzer and digest
- DMARC reporting runs alongside SPF and DKIM checks. Overage is billed per 100,000 messages: $7.50 on Essential, $5 on Growth and $2 on Enterprise, so heavy senders see cost fall.
- Blocklist and IP reputation monitoring
- Monitors watch sending IPs and domains for blocklist listings and reputation changes. Essential includes 10 IP reputation monitors and Enterprise includes 25, plus uptime monitors on every plan.
- Content analysis
- The message is analyzed before a campaign goes out, so wording and structure issues that tend to trigger spam filters can be fixed ahead of the send rather than after.
- API, MCP and Gappie
- The pricing page has an AI section listing API and MCP options and a free tool called Gappie. The page does not describe what Gappie does.
How GlockApps handles your data
The vendor's data terms were not verified. The privacy policy pages tried returned HTTP 404, and the pricing page opened states no training policy, retention period, hosting region or certification. Because testing sends sample messages and domain data to the service, request the vendor's policy in writing before using real customer content. The pricing page lists Google Postmaster Tool integration, which reads reputation data from Google under the connected account.
Where GlockApps falls short in practice
- Credits cap testing volume. Free has 2 spam test credits and Essential 360. A team that tests every segment of every campaign can burn through credits and need Growth or a credit pack.
- Unpriced add-ons. Bundle, DMARC Analytics and Spam Test Credit Packs are listed without prices. Needs above Enterprise go to a Custom option through sales, so large senders cannot budget from the page.
- Seat and domain limits. Postmaster Tool users are 1 on Free and Essential, 5 on Growth and 10 on Enterprise. DMARKOFF domains are 0 on Free and 3 to 9 on paid plans.
