I’m struggeling with using a webhook within a campaign to validate the email address before it is stored and used.  
I can add the Webhook, but is seems I cannot process data received from the webhook. For example: add a condition after the webhook so that we can decide what to do with the data returned from the webhook.

How can I add email validation, using an external webhook and preferred within a campaign, and filter out unwanted email addresses?

You will need to use N8N, or another similar tool, to receive the response and evaluate whether to mark the contact as “Do Not Contact” or not.

Hi Sandro,

thank you for your answer on my question asked.  
I’ve seen the possibilities of N8N and [Make.com](http://Make.com), but would love an option without using extra (paid) external toolings to process the respons of the webhook/API directly within Mautic.  
Doesn’t Mautic offer an option to directly process data received from Webhook (where possible directly from the campaigner)?

Hi,

Another option is to develop a plugin to handle the response.

I think it’s impossible to create a “universal” plugin, because each email verification tool will respond in a different way.
