FAQ

Get answers to common questions about Lessie AI.

What is an email addresses list?

An email addresses list is a curated collection of email contacts organized by criteria such as industry, job title, company size, or location. Businesses use email lists for marketing campaigns, sales outreach, recruiting, and partnership development. Quality email lists contain verified, up-to-date contacts with relevant professional information.

How can I build a targeted email list?

With Lessie AI, you can build targeted email lists by specifying your ideal contact profile — industry, job title, company, location, and more. Our AI-powered people search agent scans real-time data sources to find matching contacts with verified email addresses. Unlike static email databases, Lessie AI's lists are always fresh and tailored to your exact needs.

Is it legal to use email address lists for outreach?

Yes, using email lists for B2B outreach is generally legal when done properly. Under GDPR, CAN-SPAM, and similar regulations, you can send business emails if you have a legitimate interest, provide an opt-out mechanism, and include your business identity. Lessie AI sources data from publicly available professional profiles and business directories, ensuring compliance with data protection regulations.

How is Lessie AI different from buying static email lists?

Static email lists become outdated quickly — studies show 22-30% of email data decays annually. Lessie AI builds your list on-demand using real-time AI-powered search, so every contact is current. You also get richer data including social profiles, company info, and professional background — not just an email address. Plus, you can refine and customize your search criteria infinitely.

What industries and roles are covered?

Lessie AI covers virtually every industry and professional role. Popular categories include tech executives, marketing professionals, startup founders, investors & VCs, e-commerce managers, healthcare professionals, real estate agents, financial advisors, HR directors, and media contacts. If someone has a professional online presence, Lessie AI can likely find them.

How fresh and accurate is the email data?

Lessie AI searches in real-time rather than relying on a pre-built database. This means you get the most current data available. Each contact's information is gathered from multiple sources and cross-referenced for accuracy. You can also verify any email address using our free Email Verifier tool to confirm deliverability before sending.

Can I export my email list?

Yes, Lessie AI allows you to export your email addresses list in CSV format, making it easy to import into any email marketing platform (Mailchimp, HubSpot, Salesforce, etc.), CRM system, or outreach tool. You can then launch personalized campaigns using our AI email marketing platform. Exported data includes email addresses along with names, titles, companies, and other available information.

How much does it cost to build an email list?

Lessie AI offers a free tier that lets you start searching and building email lists immediately. You can explore contacts, view profiles, and export a limited number of results for free. For larger lists and advanced features, affordable paid plans are available. Unlike traditional email list vendors that charge per contact, Lessie AI gives you unlimited search flexibility.

How do I verify the emails in my list?

After building your email list, use our free Email Verifier tool to check each address for validity. It performs DNS lookups, MX record checks, disposable email detection, and returns a deliverability score. You can bulk verify up to 500 emails at once — paste them directly or upload a CSV file. Once verified, use our AI email outreach tool to send personalized messages at scale.

What makes a good email addresses list for marketing?

A high-quality email addresses list for marketing should have: verified and deliverable email addresses, relevant audience targeting (right industry, role, and company size), fresh data (updated within the last 3-6 months), additional context like name and title for personalization, and compliance with email regulations. Lessie AI helps you build lists that meet all these criteria. Explore our B2B lead generation platform for advanced prospecting workflows.
