AiIndex is built on a principle of curated selection, not automated aggregation. While many directories list thousands of tools with minimal vetting, AiIndex hand-picks each entry based on its utility, seriousness, and relevance for professional users. This quality-over-quantity approach saves time and provides a trusted, signal-over-noise resource for decision-makers.

How often is the directory updated?

The directory receives daily updates. This ensures that the listings reflect the most current launches and developments in the fast-moving AI and SaaS landscape. Users can rely on AiIndex for a timely and up-to-date overview of available tools.

Can I submit my own AI tool to be listed?

Is AiIndex free to use?

Based on the provided context, accessing the core directory for browsing, searching, and discovering tools appears to be a free service for users. The platform may offer additional featured listings or sponsorship spots for tool providers, as indicated by the "Sponsor Spots" metric on the site.

B2B Email Verifier FAQ

How does your email verifier work?

Our verifier uses a sophisticated, multi-step process designed for B2B accuracy. It checks the email syntax for correct format, verifies the domain exists and is configured to receive mail, and performs a real-time ping on the mailbox server to confirm the specific address is active and accepting messages. This comprehensive approach ensures we identify catch-all servers, disposable emails, and other risks.

Can I verify emails in bulk?

Absolutely. B2B Email Verifier is built for scale. You can upload a CSV or Excel file containing thousands of email addresses. Our system processes them rapidly in the cloud, providing you with a detailed report that categorizes each address as valid, invalid, risky, or unknown, allowing for easy list segmentation and cleaning.

What happens if I exceed my credit limit?

Each verification of a single email address consumes one credit. If you exceed your monthly plan's credit limit, you will have the option to purchase an additional credit pack to continue verification, or your access will resume at the start of your next billing cycle. We recommend monitoring your usage or selecting a plan that aligns with your volume needs.

Can I receive support if I need it?

Yes, dedicated support is a core part of our service. You can reach out to our friendly and knowledgeable team directly through the chat function on our website or via our contact channels. We are committed to helping you resolve any questions or technical issues to ensure you get the maximum value from the tool.
