What exactly does an email verifier do?

An email verifier is like a digital detective for email addresses. It doesn't just check if an address looks right (like [email protected]); it performs a series of technical investigations. This includes validating the correct syntax, pinging the domain to confirm it exists and is configured to receive email (via MX records), and looking for signals that indicate whether the mailbox is likely active. It does all this without sending a single email to the address, making it a safe and instant pre-check tool.

How is this tool completely free with no sign-up?

We believe powerful tools for business growth should be accessible to everyone. Craften has built this verifier as a cornerstone of our software ecosystem to provide immediate value and demonstrate our expertise. By offering it for free with no account required, we help you solve a critical pain point instantly. It's a win-win: you get a top-tier tool at zero cost, and we get to support amazing people building incredible things.

What's the difference between format validation and deliverability checking?

Format validation is the first basic check—it ensures the email follows the standard structure (e.g., no spaces, has an '@' symbol and a domain). Deliverability checking goes miles deeper. It involves verifying that the domain is real, has live mail servers (MX records), and doesn't exhibit signs of being a disposable or role-based address that could harm your sender score. Our tool does both, giving you a complete picture of an address's health.

Can I verify an entire mailing list with this free tool?

Our current browser-based tool is optimized for lightning-fast, single-email verification, perfect for spot-checking and cleaning smaller lists manually. For bulk verification of entire lists containing thousands of addresses, we recommend exploring dedicated bulk email verification services that are built for that specific high-volume workflow. This tool is your go-to for instant, on-demand validation.

What types of data can I extract using Crawlkit?

CrawlKit allows you to extract structured data from a wide range of sources, including LinkedIn profiles, Instagram accounts, app reviews from the Play Store and App Store, and much more, all through a single API.

How does Crawlkit handle anti-bot protections?

CrawlKit automatically manages proxy rotation and implements advanced techniques to bypass anti-bot protections, ensuring your data requests are successful and minimizing the chances of being blocked.

Is there a limit on API calls?

CrawlKit operates on a credit-based system with no monthly commitments or rate limits. Your credits never expire, allowing you to scale your data extraction needs without worrying about hitting usage caps.

Can I integrate Crawlkit with my existing tools?

Absolutely! CrawlKit is designed to work with any programming language and automation tool, making integration seamless. You can easily use it alongside platforms like Node.js, AWS, and more, without any restrictions.
