To set up your business email ID for all outgoing emails to your customers, use the Mail Settings option located within the Settings tab of the Web App.
Settings > Preferences > Mail Settings and click on Setup Mail
The ‘Allow in-app emails’ option will be checked off by default. This is to ensure that in the event there is an issue with your email provider channel, the in-app emails will be sent using the ReachOut email channel.
PLEASE NOTE: The SMTP set up and the verification process may vary for each email provider. Please refer to our Email Set-up Reference Guide for additional information.
