Hi, @matttunney, if your goal is to send everyone who fills out a form on your website the latest content you’re creating, then consider adding that as an opt-in option on your forms. Per @Anonymous’s point, you want to make sure you’re being upfront with content you’re going to send someone. Sending content to someone that isn’t expecting it can lead to them unsubscribing.
Another option that will reduce frequency of emails to your audience while still promoting content you have to offer is to create a monthly newsletter that highlights blogs, company updates, promotions, etc.
