You can optionally use a custom SMTP server to improve the delivery of your emails. Please note that if you choose to use your own SMTP server for Newsletters you will not be charged marketing credits but will also not have access to reporting capability regarding email views, sends, bounces etc. Regardless of the settings on this screen, automatic updates are always delivered via our servers.
If you have any questions or require further information regarding the functionality please contact the Rex Support Team.
