Overview
GlockApps
GlockApps helps you solve the frustrating problem of emails disappearing into spam folders or being blocked by providers. You can run comprehensive delivery tests across major providers like Gmail, Outlook, and Yahoo to see exactly where your messages land before you hit send on a major campaign. The platform identifies specific technical issues with your authentication or content that might be triggering spam filters.
Beyond one-time testing, you can monitor your sender reputation and DMARC compliance in real-time to protect your domain from spoofing. It provides actionable reports that tell you how to fix IP blacklisting and DNS configuration errors. Whether you are a solo marketer or a high-volume sender, the platform gives you the visibility needed to maintain high open rates and protect your sender authority.
Email on Acid
Email on Acid helps you eliminate the guesswork of email marketing by previewing your campaigns across over 100 different email clients and devices. You can catch rendering issues, broken links, and accessibility problems before you hit send, ensuring every subscriber has a consistent experience. The platform automates the tedious manual testing process, allowing your team to deploy high-quality emails faster and with more confidence.
Beyond simple previews, you can optimize your inbox placement with deliverability tools that check your IP against blacklists and validate your SPF and DKIM records. Whether you are a solo developer or part of a large enterprise marketing team, the platform provides the technical insights needed to bypass spam filters and improve engagement. You can integrate these checks directly into your existing workflow to maintain brand standards across every communication.
