A partner that we are working with is sending an email (using Eloqua) to their database promoting one of our webinars which is housed in Marketo using On24 integration. They requested that we automatically pass over anyone that signs up from their email blast. She mentioned that someone in an Eloqua community recommended to use a webhook to accomplish and I am unfamiliar with its capabilities. Ultimately she wants to avoid us manually pulling spreadsheets and sending them back to her in order to suppress from the 2nd and 3rd email blast. Any suggestions are greatly appreciated!
