Clerk.io

Clerk.io is an all-in-one personalization engine designed to help you grow your e-commerce store through automation. Instead of manually setting up rules, you can use its proprietary AI to analyze customer behavior, product trends, and transactions in real-time. This allows you to deliver highly relevant shopping experiences that mirror the service of a high-end boutique, but at a massive scale across your entire digital storefront.

You can implement intelligent search that understands intent, product recommendations that drive higher order values, and automated email triggers that bring customers back. The platform is built specifically for e-commerce managers and owners who want to increase conversion rates and average order value without spending hours on manual merchandising or complex technical configurations.

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.
