# How to validate a contact's email in HubSpot using the Koalify Email Validation Card
## The Koalify Email Validation Card lets you check whether a contact's email address is valid directly from the HubSpot record page, in one click, without leaving HubSpot.
### Before you begin
Make sure the [Koalify Email Validation Card is enabled and visible](https://koalify.io/email-validation-knowledge-base/how-to-add-the-koalify-email-validation-card-in-the-right-sidebar-of-hubspot-contacts?hsLang=en) in the right-hand sidebar of your contact records.
### When to use the Email Validation Card
Use the card any time you want to check whether an email address on a contact record is deliverable, for example:
- Before enrolling a contact in a sequence or campaign
- After a data import or enrichment run
- When a contact's email looks suspect or was entered manually
### How to validate an email
Open any contact record in HubSpot. In the right-hand sidebar, locate the **Koalify Email Validation Card**.
Click **Validate** to run an instant check on the email address currently saved to the contact.
The result appears immediately in the card, no leaving HubSpot.

- The result is **visible to anyone** with access to the contact in HubSpot.
- You can **re-validate at any time** — for example, after updating the email address — by clicking Validate again.
