What GlockApps does

GlockApps, operated under Deluxe Custom Apps LLC (Wyoming) with the trademark held by Hi Prime Apps Inc., is a bootstrapped email deliverability and security platform that has operated for over 15 years from Pinedale, Wyoming. Its core product is Inbox Insight, a seed-based spam-testing tool that evaluates email placement across 115 seed addresses and 5 spam filters (Google, Barracuda, SpamAssassin) while monitoring sender reputation against 50+ industry blocklists. The platform has expanded into a multi-product suite comprising DMARC Analyzer (with 10,000 free DMARC messages monthly, SPF/DKIM authentication, and unlimited domains), Uptime Monitor (website and email infrastructure monitoring), and Managed Services (1-hour deliverability consulting), alongside a portfolio of free DNS authentication checkers (SPF, DKIM, DMARC, MX, TXT, BIMI) and a free AI assistant chatbot called Gappie. Native integrations with MailChimp, SendGrid, Mailgun, SparkPost, and Amazon SES, plus an API 2.0 (REST, JSON) with white-label and PDF export, enable agency and enterprise embedding. A 2024 product wave added the Google Postmaster integration, the DMARKOFF DMARC mobile app, and smarter content analysis aligned with the new Gmail/Yahoo sender requirements.

The company monetizes via tiered subscriptions: Essential at $85/month, mid-tier Growth, and Enterprise/Large Enterprise (which unlock API GET and POST access respectively), with overage fees of $7/$5/$2 per 100K DMARC messages and $1 per 2 additional uptime monitors. Custom multi-year contracts with volume-tiered DMARC pricing extend into enterprise, while the freemium entry (2 free inbox tests, 10K free DMARC messages, 14-day uptime trial) drives PLG acquisition. Go-to-market is product-led and self-serve via app.glockapps.com, supplemented by an affiliate/reseller channel and a hybrid of free webinars and paid consulting for complex deliverability engagements. Customers include email marketing agencies (Pearl Lemon, Hustler Marketing, Pilothouse, MailSoar), B2B SaaS (Upland, One Utility Bill, Jooble, Encharge, Lavender), sales engagement (Reply, throxy, Zimetrics), fintech (PastPay), and a free 20-minute introductory consultation is offered alongside 1-hour paid deliverability sessions. GlockApps is GDPR/CCPA/PDPA/FADP-compliant, hosts on AWS US East, and processes payments via Verifone (ex 2Checkout / Avangate B.V.).

Scale indicators4 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Postmark (ActiveCampaign): Postmark is a transactional email provider with built-in deliverability tracking, bounce handling, and reputation monitoring. It overlaps with GlockApps on the deliverability-monitoring side while primarily serving transactional send via its own infrastructure.
• Mailgun (Sinch): Mailgun is a transactional and marketing email API provider within Sinch. As a major ESP, it ships native deliverability analytics and is one of GlockApps' core bounce-tracking integration partners; it represents both a channel partner and a potential competitor in sender analytics.
• Validity (ReturnPath): Validity is the largest incumbent in email deliverability, formed around ReturnPath and 250ok. It offers inbox placement, reputation monitoring, and deliverability analytics directly overlapping with GlockApps' Inbox Insight and DMARC Analyzer products, but at substantially larger enterprise scale.

Direct peers

• MXToolbox: MXToolbox is a widely used free and paid DNS/email diagnostics platform covering MX, SPF, DKIM, DMARC, and blocklist checks. It directly overlaps with GlockApps' free DNS checker suite (SPF, DKIM, DMARC, MX, TXT, BIMI) and competes for SEO-driven top-of-funnel traffic.
• Litmus: Litmus offers email testing, inbox preview, and deliverability analytics used by enterprise marketers. It overlaps with GlockApps on spam testing and email analytics, with a stronger position in email creation/preview workflows and enterprise ESP partnerships.
• ZeroBounce: ZeroBounce provides email validation, deliverability testing, and inbox placement tools targeting marketers and agencies. Its freemium + credit-based model and seed-based testing closely parallel GlockApps' Inbox Insight, making it a direct SMB-focused competitor.
• Email on Acid (Sinch): Email on Acid, owned by Sinch/MessageMedia, provides email testing, content analysis, and inbox preview tools. Its content-checking and spam-filter analysis capabilities directly overlap with GlockApps' Inbox Insight content analysis and SpamAssassin scoring features.
• SendForensics: SendForensics delivers deliverability scoring, content analysis, and reputation monitoring for email marketers and agencies. Its feature set (spam score, content analysis, blocklist monitoring, DMARC/SPF/DKIM checks) maps almost 1:1 to GlockApps' Inbox Insight and DMARC Analyzer.

Emerging players

• NeverBounce: NeverBounce is an email verification and list-cleaning service. While narrower than GlockApps, it competes for the same SMB/agency buyer evaluating deliverability and list-hygiene tools alongside or instead of GlockApps.
• Kickbox: Kickbox provides email verification and deliverability scoring as a complement to email senders. While more focused on list cleaning, it overlaps with GlockApps on sender reputation diagnostics for SMB and mid-market customers.
