Zero-Login Client Review

The core magic of Boast Image. Clients never need to create an account or remember a password. You share a single, secure link via email. They click it and are instantly in the review environment, ready to click and comment on your work. This eliminates the biggest barrier to adoption, ensuring feedback comes in fast and consistently, without the dreaded "I'll do it later" ghosting.

Pixel-Perfect Annotation

Move beyond vague emails saying "make it pop." Clients and stakeholders can click directly on any element of your web page, image, or PDF to drop a pin and leave precise feedback. This contextual commenting ensures there's zero confusion about what needs to be changed, turning subjective notes into clear, actionable tasks pinned to the exact spot.

Built-In Task & Version Management

Behind the simple client interface lies a powerful project hub for your team. All incoming comments are automatically organized. You can convert feedback into trackable tasks, manage them in a Kanban board, and upload new versions of your work. Clients see a clear history of changes, eliminating the "which version are we on?" confusion and keeping everyone perfectly aligned.

Instant Web Capture (Chrome Extension)

Streamline your workflow from the very start. Our free Chrome extension lets you capture any live website—full page, visible area, or a custom region—and instantly create a feedback-ready Boast Image item without ever leaving your browser. It’s the fastest way to go from a live site to collecting client comments.

Frequently Asked Questions

100% Free Email Verifier by Craften FAQ

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.

Boast Image FAQ

Do my clients really need to create an account?

Absolutely not! This is the cornerstone of Boast Image. Your clients never need to sign up, log in, or remember a password. They access the review board through a unique link you send them. If they can open an email, they can give you feedback.

What file types can I collect feedback on?

Boast Image is built for visual feedback. You can collect comments directly on live or captured web pages (using our Chrome extension), standard image files (like JPG, PNG), and PDF documents. It's the perfect toolkit for most digital creative and review workflows.

How does version control work?

When you make updates based on feedback, you can upload a new version of your work directly into the same project. The system maintains a clear history, and clients can easily toggle between versions to see what has changed, ensuring everyone is always looking at the latest iteration.

Is there a free plan to try it out?

Yes! Boast Image offers a Free Forever plan that is perfect for trying the core experience. It includes 1 active project, 5 items, and allows you to invite 3 external collaborators, giving you plenty of room to see how it transforms your feedback process at no cost.
