'Or Current Resident' Recipient/Addressee Settings
Edited
The USPS is constantly upgrading and can automatically flag marketing-related mail to be returned to sender.
This can happen easily if the recipient name doesn't actually map to a current known name/resident according to the postal service.
Thanks.io has addressed this by automatically appending 'Or Current Resident' to the recipient name to avoid this issue altogether.
Settings: Card Builder
You can set each address in your mailing list to be appended by using the checkbox in the Card Builder (right before placing your order for purchase.)
Settings: Campaigns
You can set each recipient in an automatic campaign to be appended with 'Or Current Resident' as well.
Settings: API/Zapier
Finally, you can set 'Or Current Resident' to be automatically appended to each recipient via Zapier or API requests.
