In Studo, you can send an e-mail to multiple people simply by separating the e-mail addresses with a comma in the "To" field. The email will then be sent to multiple people at the same time, and recipients will see that the email has been sent to each other. For example, if you want to send an e-mail to a professor and want the secretary's office to receive a confirmation e-mail, you can enter both addresses in Studo Mail like this:
If you have received an email that was sent via "To" or "CC" to several email addresses, you can choose in the Reply section whether you want to reply to one person only or to all persons.
Best regards from the Studo Team
