SendGrid Field Definition

We provide a limited set of fields to use which you can use in the Create Form process. To view/use your SendGrid Custom Fields, click "Load Additional Fields" and check off the fields you would like to add to the form.

If you are sending information that does not require a user to fill anything out make sure the hidden setting is checked. We have added a few hidden fields that are commonly used:

  • Current url (the url a user is on when they submit the form)
  • IP address (the visitor’s IP address)
  • Coupon code (the coupon code they receive in the post engagement)
  • Referring url (the url the user clicked on to get to the new page in your website.)
  • Previous Domain Referring URL (the url of the last page)
  • First url visitor landed on (the url the user first landed on)


configure settings



To view/use your SendGrid Custom Fields, click "Load Additional Fields" and check off the fields you would like to add to the form. You can also select "Add New Fields" which will give you the option for other fields you can place down.

Create Form

Once you have finalized the fields to use, click “Create Form” then arrange the fields are your promotion as desired.

Preview and Publish Your Changes

Once you have arranged all fields, be sure to SAVE and then Preview or Publish your Promotion.
