Glock Apps

Overview

GlockApps is an email deliverability testing and monitoring platform that has been helping businesses optimize their inbox placement for over 15 years. The platform provides a comprehensive suite of tools including inbox placement testing, spam score analysis, DMARC authentication monitoring, domain and IP reputation tracking, and blocklist monitoring across over 50 industry databases. GlockApps serves email marketers, agencies, SaaS businesses, and ecommerce companies who need to ensure their messages reach subscriber inboxes rather than spam folders.

What differentiates GlockApps from basic email verification tools is its focus on proactive deliverability testing and diagnostics rather than just list cleaning. The platform uses a seed list of over 100 managed email accounts across major providers including Gmail, Outlook, Yahoo, and AOL, as well as local European providers in Germany, France, Italy, and Portugal. By sending test emails to this seed list before launching campaigns, newsletter creators can identify deliverability problems, authentication issues, content triggers, and spam filter reactions before they impact actual subscribers. The platform analyzes emails through multiple spam filters including Google, SpamAssassin, and Barracuda, provides detailed reports with specific action steps, and monitors your domain health continuously to catch problems before they damage sender reputation.

Best For

GlockApps is ideal for newsletter creators, email marketers, and businesses who send regular email campaigns and want to maximize inbox placement rates. The platform works particularly well for creators who have experienced declining open rates, increasing spam complaints, or deliverability issues with specific email providers. Email marketers who manage multiple clients or campaigns will appreciate the project folder organization and white-label reporting capabilities. Newsletter creators who use dedicated sending IPs, manage their own email infrastructure, or have technical knowledge about email authentication will benefit most from the detailed diagnostics and technical recommendations GlockApps provides.

Key Features

• Comprehensive Inbox Placement Testing: GlockApps sends your test emails to a seed list of over 100 managed mailboxes across major providers and shows exactly where your messages land, whether in the primary inbox, promotions tab, spam folder, or missing entirely. This placement visibility across different email clients helps newsletter creators understand how various providers treat their content and identify provider-specific deliverability issues before sending campaigns to their full subscriber list.

• Multi-Filter Spam Score Analysis: The platform runs your email content through major spam filters including Google Spam Filter, SpamAssassin, Barracuda, ProofPoint, and Microsoft Spam Filter, providing individual spam scores for each filter. This multi-filter approach reveals which specific spam detection systems might flag your content and why, allowing you to fix issues that would otherwise send your newsletters to spam folders automatically.

• Domain and IP Analytics: GlockApps monitors your sending domain and IP addresses against over 50 industry blocklists, providing immediate alerts if you appear on any blacklist database. The platform also tracks the entire chain of IP addresses used to deliver your emails, giving you a detailed report with sender scores, blocklist records, and inbox placement statistics for each IP address in your delivery path.

• DMARC Authentication Monitoring: The platform provides continuous DMARC monitoring with 10,000 free messages per month, offering detailed daily reports and instant notifications about suspicious activity or authentication failures. This monitoring helps prevent email spoofing and phishing attacks that could damage your sender reputation, while ensuring your SPF, DKIM, and DMARC records are properly configured and functioning correctly.

• Content and HTML Analysis: GlockApps analyzes your email content for broken HTML code, broken links, oversized images, suspicious attachments, and spam trigger words that could hurt deliverability. The platform checks that URLs are valid and not on domain blacklists, verifies HTML compatibility across devices, and provides specific recommendations about content elements that need fixing before sending.

• Automated Testing and Real-Time Alerts: Newsletter creators can set up automatic inbox placement tests that run on a schedule and receive instant notifications via email, Slack, or Telegram whenever deliverability issues are detected. This proactive monitoring allows you to catch problems immediately and switch mailboxes or adjust campaigns before they impact your sender reputation with subscribers.

• Google Postmaster Integration: The platform integrates with Google Postmaster Tools to monitor domain data in a user-friendly interface with trend visualization, storing your metrics longer than Google's default period. This integration provides insights into spam rates, reputation scores, encryption status, and feedback loop data directly from Google, helping you understand how Gmail specifically perceives your sending domain.

• Actionable Recommendations: Beyond just reporting problems, GlockApps provides detailed action steps with specific troubleshooting guidance for fixing identified issues. The platform collects information from message headers, content analysis, and spam filter reports to generate prioritized recommendations that help newsletter creators resolve deliverability problems systematically.

• API Integration and White-Label Reports: GlockApps offers API 2.0 for integrating spam testing capabilities into other applications, with project management features that let agencies organize tests by client folders. The platform includes PDF export and white-label features that allow agencies to customize and brand deliverability reports with their own logo and styling before sharing with clients.

• Template Editor and Preview Tools: The platform includes a template editor that identifies risky content and HTML errors before sending, along with preview tools that show how your email appears on desktop and mobile screens. Newsletter creators can also share email previews easily through public links, making it simple to review designs and content with team members before finalizing campaigns.
