HeySummit will create a unique email address for your event where all emails will be sent from, but if you'd like to add your email address, navigate to Event Setup> Settings> Custom Email Settings.
Note this feature is only available under our Business/Success plan.
After adding your email address, we'll send you an email to verify this account. We also recommend adding DKIM to improve the deliverability of all emails.
To learn more about DKIM, here's an article with more information.
