RE: Block Email Addresses for Autoresponse in Record Creation and Update Rule
Hi
If you want to have more control over the Auto - Response email, you could try the following
You can have a flag field on the Case or whatever the entity used to create the record and set the flag value to Yes in your create step in the rule.
You can then have a workflow that triggers On Create of the record and checks if its auto created a record and if it is an auto-created record, you can actually send the auto-response from this Workflow.
In the workflow, you can check the email address, if its certain email, you do not have to send an email.
Let me know if you need further info or guidance on this.
The main benefit of moving email sending to your workflow is that you will have more control over and you can add more features or conditions as and when you require in the future
