What customers say
Since years, Tomba has provided the most results per search, and still it keeps getting better. On top of this, it recently became one of the most feature-rich tools for our list building. I highly recommend Tomba.
Steffen BurandtHead of Business Development, Chandler OrchardsI spend 3+ months creating best in class content in the form of data-based research studies. When all is said and done, Tomba is the tool I turn to. Tomba finding the contacts for the perfect prospects at scale is game changing in helping us promote.

What teams build with Domain Search
- Account mappingSee who works at a target account, and in which team, before you choose a first contact.
- Founder-led salesFind the decision makers at your first hundred target accounts.
- Client researchBuild a contact sheet for each client prospect with one search per domain.
- Exposure auditsList the addresses of your own domain that are public on the web, and where they appear.
Every email returned comes with a clear accuracy indicator. Verified emails are addresses we have recently confirmed as deliverable: marked with a green Verified badge. Other emails include a confidence score based on SMTP checks, source reliability, pattern matching, and other signals so you can decide which contacts to prioritize.
All email addresses are compiled from publicly available online sources. Each result includes the source URLs and discovery dates so you can trace exactly where the data originated.
Yes. If you know someone's full name and their company domain, use the Email Finder tool to locate their verified email address instantly.
Yes. Paste any LinkedIn profile URL into the LinkedIn Finder tool to get a verified email address.
Each query counts as one search request for every ten emails retrieved. For example, 43 emails for a domain equals 5 search requests. Free accounts get 25 free search credits every 30 days. Need more? Check our pricing plans.
Limits are per plan and per endpoint, in requests a second / a minute / a day: Free 1 / 2 / 5, Basic 3 / 50 / 500, Growth 5 / 80 / 1,000, Pro 8 / 150 / 4,000. Pro Plus and Scale have no limit, and Enterprise allows 100,000 requests a day with no per-second limit. Every response carries rate-limit headers; see Rate limits.
Yes. Configure a webhook URL in your dashboard or when creating a bulk operation. Tomba sends a POST notification with the operation ID and status when processing completes.
Yes. Tomba has native apps for n8n, Make, and Zapier, so you can pull every email on a domain inside an automated workflow without writing code. Common setups: expand a new account into its full contact list, enrich inbound leads by company domain, or push results straight to your CRM. If you would rather build it yourself, use the Domain Search API, the CLI, or our MCP server for AI agents.
Yes. Some domains are catch-all (accept-all): the mail server accepts any address, so a standard SMTP check cannot prove a specific mailbox exists. Tomba flags catch-all domains in the results instead of reporting every address as verified, so you know which contacts carry bounce risk before you send. To work these domains deliberately, use the Catch-All Finder and the Catch-All Verifier.
