GlockApps

Learn More
The go-to tool for seeing exactly where a send lands — inbox, spam, or a promotions tab — across major providers, though credit-based pricing gets expensive for frequent testers.

What it does

GlockApps runs inbox placement tests across major inbox providers, tests emails against spam filters, checks SPF/DKIM/DMARC authentication, and monitors domain and IP reputation against 50+ blocklists. Each test consumes a credit, and reports show which providers routed the send to inbox, spam, or a tab like Gmail Promotions.
