Overview

Tomba is an email finding and verification service geared toward B2B sales outreach, letting you look up professional email addresses by name and company domain or verify whether an email address is deliverable. The API integrates easily into sales automation tools, CRM enrichment pipelines, or lead generation scripts. A free tier is available that includes a limited number of searches per month.
