You can do it without zapier but you do need to have a script of some kind that is triggered using the webhook and takes the payload and emails it to you. You canât just program webhooks to send you an email.
For the example you give, you could also enable must approve users but then that would restrict login until you approve the new user manually.
Are you looking for a little nudge for when someone first joins?
If youâre not tied to webhooks you could create a data explorer query and use a recurring Automation to send you a PM whenever there are new results.
I suggested a similar thing for a slightly different use case here:
Automation is a good idea! I just tested this and you can actually use an existing automation, if youâre willing to create a user custom field and require your users to complete it at signup.
