Export your contact list from HubSpot, Salesforce, or a CSV. Paste the emails here. Get a list of unique company domains sorted by contact count. This tells you which companies you have the most contacts at — your warmest accounts. Import the domain list into LinkedIn Sales Navigator or Apollo to build targeted account lists.
Gmail.com, Yahoo.com, and Outlook.com aren't company domains — they're personal email providers. Filtering them out gives you a clean list of business domains only. If someone uses [email protected], they're not reachable through a company domain for B2B outreach.
