Overview
MxToolbox
MxToolbox is your go-to platform for diagnosing and monitoring email delivery and infrastructure health. You can perform instant lookups for MX records, DNS configurations, and blacklist status to identify why your emails might be landing in spam folders. It simplifies the technical complexity of email protocols like SPF, DKIM, and DMARC by providing clear, actionable reports that show you exactly what needs fixing.
You can also set up automated monitoring to get alerted the moment your domain appears on a blacklist or if your mail server goes offline. This proactive approach helps you protect your brand reputation and ensures your critical communications always reach their destination. Whether you are an IT professional managing multiple domains or a small business owner troubleshooting a single mail server, the platform provides the visibility you need to keep your email systems running smoothly.
ZeroBounce
ZeroBounce helps you protect your sender reputation by removing invalid, risky, and inactive email addresses from your marketing lists. You can upload your entire database for bulk cleaning or use the real-time API to verify emails the moment they are entered into your signup forms. This prevents bounces before they happen and keeps your data clean from the start.
Beyond simple verification, you can use the platform to test your email deliverability and monitor your blacklists. It identifies high-risk emails like spam traps and catch-all addresses that typical checkers might miss. Whether you are a solo marketer or part of a global enterprise, these tools help you increase open rates and maximize the ROI of your email campaigns.
