Can I capture multiple email addresses in a form to send emails?
Hello,
We have created a process that allows our sales agents to send "triggered" emails to customers using a Marketo form and landing page. The way it works is the sales agent goes to our landing page and fills out the form below, entering the email address that should receive the email (Member's Membermaint Email Address) + the agent's information:

Upon clicking "Send Email", some of the information that the agent enters in the form populates the agent trigger tokens in the email:

Recently, one of our agents asked us if it's possible for us to set up a way for them to enter multiple member email addresses into a single field, then send these email addresses the same email, populated with the agent's information.
I have seen a couple of articles mentioning this could be accomplished with JavaScript, but they did not provide details or instructions on how to set this up.
Does anyone know if this is possible, and if so how? Please provide step-by-step instructions.
Thank you,
LK
