You can send a test version of your marketing email to yourself or a team member before you send out the actual email to your contacts.
To send a test email:
In your HubSpot account, navigate to Marketing > Email.
Hover over the name of a draft email and click Edit.
In the upper right, click Send test email.
In the right pane, click the Choose one or more recipients dropdown menu to select recipients for your test email.
(Optional) Click the Receive as specific contact dropdown menu to preview the email as it will appear to a specific contact. Selecting this option can be helpful if you want to test personalization in your email.
Click Send test email.
Why are test emails sent from email@example.com?
All test emails are sent from firstname.lastname@example.org, to protect your email deliverability rates. When you send the email to your contacts, it will be sent with the From name and From address you've specified.
