How does Pitchbox handle contact forms?

You can still reach out to an opportunity even if it doesn’t have a contact! While personalizing, open the site in a new tab and find the contact form URL. Add the Contact Form URL while personalizing by checking the “Email not found, but this site has a contact form” box and a new field will pop-up. Copy and paste the contact form URL into the field.

When composing, copy your template into your email like normal and click 'Next'.

You will be taken to a screen that has your email template and a button that says "Copy Body to Clipboard and Open Form." Click this button to open the contact form in a new tab and copy in your message. 

When you are done, submit the contact form and click the 'Mark as Sent' button in Pitchbox. This will add your message as a sent opportunity in Pitchbox.
