Hi, Tyler. Thanks for your interest in our plugin suite.
Our emails use the wp_mail() function so all the emails from your site (e.g. password reset emails) must be coming from that same email address.
Please reference http://www.wpbeginner.com/plugins/how-to-change-sender-name-in-outgoing-wordpress-email/ or a similar resource to learn how.
Please note that you posted in our Pre-Sales forum from a user account that doesn’t have any purchases associated with it.
We don’t answer support questions for The Events Calendar core/free or Event Tickets core/free or their paid add-ons in the Pre-Sales forum. The information I provided above does not require one of our paid add-ons.
If you made your purchase(s) through a different user account, please login to that account and then post in one of the paid forums.
Thank you for your understanding and thank you for using our plugins.
