Create an Email Alias and Set Up Forwarding
NetSuite generates an email address for use with the plug-in implementation. Users can send email messages to the implementation’s email address for processing. However, you may want to create an email alias on your company mail server to mask the email address required by the plug-in implementation.
For example, if your account ID was 123456, the NetSuite-generated email address for a plug-in implementation would look something like emails.123456.xxx.xxx@1234567.email.netsuite.com. The implementation processes uses that email address to send invoice records from NetSuite. You can create an email alias named invoices@example.com on your company mail server that forwards to the implementation email address.
The process to set up an email alias and forwarding varies by provider. Consult the documentation for your email software for instructions.
You can then inform customers that they should send their invoices to invoices@example.com.
