[Working with contact data](https://portal.snapaddy.com/knowledge/snapaddy-leadresearch?hsLang=en#working-with-contact-data) # How does the snapAddy e-mail validator work? ## The snapAddy email validator determines the most likely business email address of a contact person in snapAddy LeadResearch. You add the suggested address to the contact with a single click. ### What does the snapAddy email validator do? The snapAddy email validator checks common email patterns of a company domain, for example `firstname.lastname@company.com`, and suggests the email address with the highest probability. Each suggestion is displayed with a probability in percent, so you can assess the quality of the match right away. ### How do I start the email validator in LeadResearch? You start the email validator via the **Email** button in the contact view of your contact person in snapAddy LeadResearch. 1. Open the desired contact person in [snapAddy LeadResearch](https://app.snapaddy.com/lead-research/list). 2. Click the **Email** button. The **snapAddy email validator** window opens. 3. Check the company website in the input field, for example `https://snapaddy.com`, and click **Search**. ![](https://portal.snapaddy.com/hs-fs/hubfs/undefined-Jul-20-2026-01-52-19-5663-PM.png?width=545&height=96&name=undefined-Jul-20-2026-01-52-19-5663-PM.png) ### How do I add the suggested email address to the contact? Click **Select** next to the desired email address. The email address then appears in the email field of the respective contact. Under **Most likely email address** you see the best match including its percentage. Under **Other possible email addresses** you find alternative variants with a lower probability, which you can also add via **Select**. ![](https://portal.snapaddy.com/hs-fs/hubfs/undefined-Jul-20-2026-01-52-19-8253-PM.png?width=470&height=289&name=undefined-Jul-20-2026-01-52-19-8253-PM.png) ### Which questions commonly come up next? #### Is the email validator also available in the VisitReport app? Yes, the email validator is also available in the VisitReport app. There it validates the email address based on the first name, last name, and website entered in the contact data. You can find the instructions in the article [E-mail validator in the VisitReport app](https://portal.snapaddy.com/knowledge/e-mail-validator-in-the-visitreport-app?hsLang=en). #### Can I find my own email address with snapAddy?

The article [Can I find my own email address with snapAddy?](https://portal.snapaddy.com/knowledge/kann-ich-mit-snapaddy-meine-eigene-e-mail-adresse-herausfinden?hsLang=en) explains the background. #### Does email validation also run when importing from business networks? Yes, when transferring contact data from business networks via the direct integration or the **Transfer** button, email validation runs automatically in the background. You can find the details in the article [How do I import data from business socials into LeadResearch or my CRM system?](https://portal.snapaddy.com/knowledge/dataquality-directintegration-in-linkedin?hsLang=en) If you have more questions, feel free to contact our support under [support@snapaddy.com](mailto:support@snapaddy.com) or your Customer Success Manager.   -
