Update: this functionality was disabled by Alexa in a recent update, so you are no longer able to delete contacts from Alexa.
If you need to edit or remove a contact from Alexa you will need to go to the Alexa app on your device.
Open the Alexa app. Go to Conversations tab in your Alexa account.
Click on the contacts icon in Alexa. It will show you all of the contacts that you have.
Locate the contact that you wish to delete and select that contact and then click on the delete or block button.
We are obsessed with everything about contacts so feel free to reach out to us on firstname.lastname@example.org.
