BounceProof is an email validation tool that filters hard bounces, catch-all emails, disposable addresses, and spam traps after discovery to protect deliverability. 98.5% accuracy helps BounceProof identify risky emails that average email validators miss at scale. 20% of email lists contain invalid or risky addresses that later cause hard bounces and deliverability issues. 2% or higher email bounce rates damage sender reputation and reduce inbox placement over time. 70% faster email validation than most competitors lets BounceProof process large lists without delays.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
