Hover to Verify
Move your cursor near any email on any webpage. A small verify badge appears right next to it. With one click, you get instant results without leaving the page.

Works Where You Work
LinkedIn, Apollo, HubSpot, Gmail or any page with an email on it. Once verified, a color-coded dot stays inline so you can scan an entire list at a glance.
Domain Intelligence
One click opens a deep enrichment panel. SPF and DMARC records, domain age, and blocklist status provide everything you need to trust the domain.

Where teams use InboxCheck most
InboxCheck makes the most sense when a rep is already on the page, already looking at a contact, and needs a clean decision before a send. Start with the workflow that matches how your team prospects today.
Cold email campaigns

Gmail and Google Workspace

Apollo prospecting
Turn found contacts into checked contacts before they reach your CRM or outreach tool.
LinkedIn prospecting

Core pages that explain every verdict
The site now has a clear reference layer for teams that want to understand the mechanics behind Safe, Risky, and Unsafe. These pages support the workflow guides and make the product easier to evaluate.
Email verification fundamentals
Start here if you want the plain-language definition, the business case, and the limits of verification.
How verification works
Understand syntax checks, MX lookups, SMTP verification, catch-all behavior, and disposable domains.
Research on data decay
Review first-party findings on why sourced B2B data becomes unreliable faster than most teams assume.
Alternatives and comparisons
Compare InboxCheck with finder tools and bulk cleaners based on workflow fit instead of feature lists alone.
InboxCheck works best when verification happens at the point of action.
That is the core product idea behind every page in the new content system. Learn the fundamentals, read the research, then jump into the workflow that matches where your team spends its day.
