How can I change who the email sender is?
I think you could also do it by a simple filter or plugin: https://enriquechavez.co/change-email-sender-wordpress/
No need to use SMTP.
However these filters will change sender/e-mail for all e-mails, not only Anspress, which could have impact on other plugins, i.e. WooCommerce or Gravity Forms, which is not so great.
I would use it with caution.
