# BounceGuard - **Website:** - **Primary alias:** `bounceguard.app` ## Description BounceGuard is an email verification and deliverability platform that helps businesses clean contact lists, protect sender reputation, and prepare leads for outreach. Its bulk validation checks addresses against eight signals, including syntax, MX records, SPF, DMARC, disposable domains, catch-all behavior, and blacklists. Results are classified as Okay, Maybe, or Bad, with clear explanations so users can assess risk before sending. Customers can upload or paste contacts, find leads through sources such as Apollo, Hunter, Snov, GitHub, and a directory of YC-backed startups, then send validated lists to tools including Smartlead, Instantly, Lemlist, HubSpot, and Mailchimp. BounceGuard also offers a real-time verification API, signup form widget, scheduled re-validation, and domain health monitoring with alerts for blacklist appearances or DNS issues. Additional tools include blacklist checking, DMARC and SPF inspection, email finding, header analysis, and spam-word scanning. Each completed validation can generate a shareable report with a list health grade, domain risk breakdown, and bounce-rate forecast. ## Industries - 🖥 Computers Electronics and Technology - 🖥 Email _(under Computers Electronics and Technology)_ - 📊 Business and Consumer Services - 📊 Online Marketing _(under Business and Consumer Services)_ ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/id-ZU9jRRn/w/64/h/43/theme/dark/logo.png?c=1bxid64Mup7aczewSAYMX&t=1791319652122) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Half Baked | #83c0d2 | accent | | Bunker | #0c0f17 | dark | | Athens Gray | #f7f8fa | light | ## Fonts - Inter — asset _(google)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
