    We are creating a contest and are using Gravity Forms. Every test email shows sender as Webmaster. We want it to say Aaron Mischel and sales@safeology as the email address. I tried to change the name in the WP Mail SMTP but now get errors. Here is the coding error:

  • Hi @electricmirror,

    Thanks for reaching out. Microsoft Office 365 SMTP does not allow you to change the sender’s addresss. You’ll need to send emails from the same email address you’ve authenticated which is your Office 365 account email. The sender’s name can be changed when you change your account’s display name.

    I hope this clarifies!
