You can create a customized email notification when new leads come in from Facebook Lead Ads using Zapier's automated workflow feature. To set up this notification, you need to connect your Facebook account and select the lead ad page and form that collects responses. You then test the trigger step to ensure it's working properly, and once confirmed, you can customize an email notification that will be sent to you (and anyone else) when a new lead comes in. The email notification can include lead data such as name or Ad ID, and can be set up with various customization options including subject line, body type, and signature. You can also use this feature with other apps like Gmail, Email by Zapier, Slack, or SMS, depending on your preferences.
