You can view contact information for a merchant by going to the merchant Overview page. Merchants > Search for Merchant > Click on the merchant you wish to contact.
There are two ways for contacting merchants:
1) Write an email from your email provider: the contact email addresses of a merchant are usually listed at the bottom of the Merchant Description page.
2) Send an email from your ShareASale account: Within the merchant overview page, you will find on the left, below the logo, the option to 'Contact' and can write your email in the pop up box so long as you are joined to the merchant program.
