What is GlockApps?
GlockApps is an email deliverability testing platform that shows whether your messages land in the inbox, the spam folder or nowhere at all. You send a test email to a set of seed addresses at providers like Gmail, Outlook and Yahoo, and GlockApps reports where each copy arrived. It also scores your message against spam filters and checks SPF, DKIM and DMARC so you can fix problems before a real campaign.
Beyond one-off tests, GlockApps monitors the health of your sending setup over time. It tracks IP and domain reputation against dozens of blocklists, runs scheduled tests with alerts, and includes a DMARC Analyzer for policy setup and reporting. Agencies can manage client projects and export white-label PDF reports. A free plan covers two spam tests and a monthly allowance of DMARC messages.
