SharePoint 2013 JS Automatically Generate and Send Email on New Item Form Save

Here is a screenshot containing the references below:

BACKGROUND (the numbers correspond with the items in the screenshot)

1. The 'Add New Item' button is pressed, which causes the 'New Item Form' Modal box to appear
2. The New Item Form Modal Box
3. Save New Item

4. HTML Image hyperlink, which generates an email and populates the Mail To, Subject, and Body fields

   • To: [email protected]
   • Subject: Text String
   • Body: 'Title' field value

Calculated column for HTML button (4):

="<a href=""[email protected]"&"?Subject="&joshTextString&"&Body="&Title&""" target=_top>"&"<img src=../SiteAssets/ICONS/sent.png style=height:20px;width:20px;/>"&"</a>"

5. Send button on the automatically generated email

QUESTION

Once the new record is saved, I'd like an email corresponding with that new item to be automatically generated and sent. I 'd prefer not to create a WF for this, because the recipient is an external user.

Is it possible to create a script to run once (3) is pressed by the USER and the record is CREATED and SAVED, which will automatically click (4) for that new item, generating a new email, and once it's generated, automatically click (5) and send the email? I don't have a button ID, because the button is not in js.
