AI-Powered Contact Discovery

Glasa’s AI search agents allow users to find ideal prospects using natural language queries. Users can simply describe their target audience by industry, job title, location, company size, or other criteria, and the AI immediately scours 800 million pre-validated contacts to deliver precise matches. The conversational interface asks clarifying questions to narrow results, ensuring every search returns highly relevant leads without manual filtering or complex Boolean queries.

Triple Verified Data Quality

Every contact in Glasa undergoes a rigorous three-layer verification process before reaching the user’s pipeline. The system performs format checks, domain verification against live mail servers, and real person confirmation to ensure accuracy. With 95% title accuracy, 99% email accuracy, and guaranteed less than 2% bounce rates, sales teams can trust that every lead is deliverable and actionable, eliminating wasted time on bad data.

Unified Inbox with AI Lead Categorization

Glasa provides a single, unified inbox where users manage all prospect communications. The AI automatically analyzes every reply, categorizing leads by interest level, flagging hot prospects, and auto-tagging messages so teams instantly know which conversations require immediate follow-up. This intelligent prioritization ensures sales representatives focus their energy on the highest-value opportunities rather than manually sorting through responses.

Flexible Sending Infrastructure and Inbox Marketplace

Users can choose their preferred sending infrastructure from Google Workspace, Microsoft Outlook, or SMTP, and even mix providers within the same campaign for optimal deliverability. Additionally, Glasa offers an inbox marketplace where users can purchase standard and pre-warmed inboxes from trusted providers. This flexibility gives teams full control over their outreach strategy while maintaining high deliverability rates across all channels.

Outbound Sales Prospecting

Sales development representatives use Glasa to rapidly build targeted prospect lists for outbound campaigns. Instead of spending hours manually researching companies and contacts, reps simply describe their ideal customer profile to the AI agent, which instantly returns verified contacts with accurate titles, company information, and direct dials. The triple verification process ensures every lead is reachable, dramatically increasing the efficiency of cold outreach efforts.

Account-Based Marketing Campaigns

Marketing teams leverage Glasa to identify and engage high-value accounts with precision. By filtering prospects by revenue, headcount trends, funding stage, technologies used, and even university backgrounds, marketers can build highly specific account lists. The platform’s AI enrichment automatically fills in missing data points, ensuring every contact profile is complete and ready for personalized multi-channel engagement.

Lead Validation and Data Cleansing

Companies with existing prospect databases use Glasa’s verification APIs to clean and validate their contact lists. The REST API allows businesses to plug email verification and contact finding directly into their own tech stack, processing high volumes of leads automatically. This ensures marketing and sales teams only invest time and resources in contacts that are accurate, deliverable, and likely to convert.

Sales and Marketing Alignment

Glasa serves as a single source of truth that aligns sales and marketing teams around shared high-value opportunities. The unified platform allows both departments to access the same verified contact data, audience lists, and engagement insights. Marketing teams can build and pass qualified audiences to sales, while sales can provide feedback on lead quality through the AI-categorized inbox, creating a continuous feedback loop that improves targeting over time.

How does Glasa verify email addresses?

Glasa uses a three-layer verification process for every email address. First, it performs a format check to ensure the email structure is valid. Second, it verifies the domain against live mail servers to confirm the domain exists and accepts mail. Third, it conducts a real person confirmation to verify the specific email address belongs to an actual individual. This process ensures 99.2% deliverability, with less than 2% bounce rates guaranteed.

Can I use my own email infrastructure with Glasa?

Yes, Glasa offers complete flexibility in choosing your sending infrastructure. You can connect Google Workspace, Microsoft Outlook, or any SMTP provider. The platform even allows you to mix multiple providers within the same campaign, giving you full control over which provider each inbox uses for outreach and warmup activities.

What is the size of Glasa’s contact database?

Glasa provides access to over 800 million pre-validated B2B contacts across more than 55 million companies worldwide. Every contact includes triple-verified email addresses and direct dials, with data synced live from 35+ sources to ensure no stale or outdated records. There are no upload limits, and users get full REST API access for integration with existing systems.

How does the AI inbox categorization work?

When prospects reply to your outreach, Glasa’s AI automatically analyzes each response and categorizes leads by interest level. The system flags hot prospects who show buying signals, auto-tags replies with relevant labels, and presents a prioritized view of all conversations. This allows sales teams to instantly see who requires immediate follow-up, who needs nurturing, and who is not interested, saving hours of manual inbox management each week.
