What GlockApps does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- A trial period for the paid plans
- Whether the free plan's 2 tests renew each month
- Whether the 2 free tests renew each month or are a one off
- How long the 10,000 free DMARC credits last, as the help article does not say
Where the sources disagree
We report each version rather than pick one.
- The pricing page lists 5 uptime monitors on Free. The uptime page offers up to 10 monitors free at 5-minute intervals and, in a separate box, a 14-day trial of 20 monitors at 1-minute intervals. The home page says up to 20 monitors free for 14 days. We report each and cannot say which applies.
- A help article last updated on 23 October 2023 says a free account gets a 14-day trial of the Uptime Monitor, while the pricing page lists 5 uptime monitors on Free without a time limit.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Use both free plans for what they cover
Warmerly's free plan shows warmup on a mailbox. GlockApps' shows two placement tests and DMARC reports. They answer different questions.
Read the uptime terms before relying on them
GlockApps' pages give different free monitor counts. Ask which applies to you.
Two tests do not last long
If you run one test on a draft and one after a fix, the 2 free GlockApps tests are gone in two sends. That is a sound way to try Inbox Insight, but not a way to track placement over a month.
Free for warmup, free for tests
Warmerly's Free plan runs warmup on 1 mailbox and 3 placement tests a month. GlockApps' Free plan runs 2 tests and 10,000 DMARC messages. Use each to try what you actually need.
