Warming up
GlockApps is a deliverability testing and DMARC monitoring platform — it runs spam-placement tests and tracks authentication, but it does not run active warmup (sending, opening, and replying to mail to build sender reputation). Most teams that use GlockApps still need a separate warmup tool alongside it.
The cheaper, specialised alternative. Warmup-only, unlimited mailboxes, daily auth checks, 5-provider placement insight.

Don't think of this as a straight swap — GlockApps and Warmerly solve different halves of the same problem. If your mail is landing in spam and you need to know why, GlockApps' testing tells you where it landed. Warmerly is what fixes it by building sender reputation through active warmup. Most serious senders eventually want both; if you can only run one, start with active warmup since it addresses the root cause.
Yes, and many teams do — Warmerly runs continuous warmup in the background, and GlockApps gives you an independent, third-party spam-placement check when you want to verify inbox placement across providers. They don't overlap; they cover different parts of the deliverability picture.
No. GlockApps tells you whether mail is landing in the inbox or spam right now — it does not change that outcome. Fixing a spam-folder problem requires rebuilding sender reputation, which is what active warmup tools like Warmerly do.
If your mail is already landing in spam, start with warmup — it addresses the root cause. Add a testing tool like GlockApps once warmup is running, to independently verify placement is actually improving.
