Our verdict on GlockApps
GlockApps is an email deliverability platform for marketers, agencies, and businesses that need to understand how messages reach recipient inboxes. It tests inbox placement across major mailbox providers, evaluates spam-filter scores, checks SPF, DKIM, and DMARC authentication, monitors domain and IP reputation, and detects blocklist listings. Its web and API access also suit teams that want deliverability checks alongside campaign or sending workflows.
The pricing structure starts with a Free plan at $0 per month, including Inbox Insight, DMARC Analytics, and Uptime Monitor. Essential costs $59 per month or $708 per year for individual use, while Growth costs $99 per month or $1,188 per year for small-to-medium businesses. Enterprise costs $129 per month or $1,548 per year for agencies. The paid tiers retain Inbox Insight, DMARC Analytics, and Uptime Monitor, with the plan positioning changing by audience. The free Inbox Insight offer provides two credits, and Uptime Monitor has a separate 14-day trial.
Its strongest fit is for teams that need more than a one-time email check. GlockApps combines spam-filter scoring with Google, Barracuda, SpamAssassin, Microsoft EOP, and Proofpoint; content, HTML, link, image, and message-size analysis; automated tests and deliverability alerts; Google Postmaster integration; and DMARC analytics. Integrations include Return Path, Mailchimp, Amazon SES, SparkPost, Mailgun, SendGrid, and Slack, while the REST API supports GET and POST access. Choose GlockApps for ongoing deliverability and sender-reputation monitoring; a narrower tool may be preferable if you only need basic message inspection.
