3) Click Account>Integration Options.
4) Select 'Email mapping' on the Online Express Options screen.

Note: Only one e-mail will be sent to a Constituent if they have one of each type selected for Primary and Secondary UNLESS the box for 'Send to ALL mapped email types for each Constituent' is marked. When this box is marked, an e-mail will be sent to each e-mail that falls within those types, even for Constituents that have both.
