absentee_address

string

The property (absentee) address for this recipient, such as a house an absentee owner owns, as opposed to where they get mail. Give either the whole address here, or the street line here with absentee_city, absentee_province and absentee_postal_code. When set, the ~ABSENTEE_STREET~, ~ABSENTEE_FULL_ADDRESS~, ~FULL_ADDRESS~ and ~STREET_VIEW~ image template variables, and %ABSENTEE_STREET% in messages, use this address instead of the mailing address. The mailer is still delivered to address. Include the city, state and ZIP so Street View finds the right property. It is stored as custom1 = absentee and custom2 = the full address and is returned that way, so it cannot be combined with custom1 or custom2: a recipient that sets either one as well is rejected with a 400.

Example:

"742 Evergreen Terrace"

absentee_city

string

City of the absentee (property) address. Requires absentee_address.

Example:

"Springfield"

absentee_province

string

State or province of the absentee (property) address. Requires absentee_address.

Example:

"IL"

absentee_postal_code

string

ZIP or postal code of the absentee (property) address. Requires absentee_address.

"62704"
