Numeric Sequence ID “From” field

Hi,

The form I developed is to generate leads. And the email is directed to a crm.
The index of this crm is the “from” field. So I need to differentiate the email from the sender so that it is not always the same customer. So I thought if it is not possible to use an email with a different numerical sequence or even as in this example: [email protected], [email protected], etc.

or whether it would be possible for the lead’s email to be considered the sender’s email. This would also be a good solution.

Any ideas on that?
