-
Import custom email phone limitation Report an error
“If your file includes both email address and phone number, it’s best to map them as default properties, not custom ones. If mapped as custom properties, they will not trigger automation workflows.”

-

-
Import subscribe status Report an error
“If either of the checkboxes is left unchecked, contacts will be imported as non-subscribed.”
-
Import duplicate handling options Report an error
“Update subscription status and contacts’ properties (Recommended): This option updates both the subscription status and any mapped contact properties in the import file. Update contacts’ properties only: This updates only the mapped contact details (e.g., name, phone number, etc.) but keeps the existing subscription status unchanged. Update subscription status only: This updates the subscription status while keeping all other contact details as they are. Do nothing: This option prevents any changes to existing contacts. Only new contacts will be imported.”
-
Import empty fields handling Report an error
“If enabled, any fields left blank in the import file will clear the corresponding existing values for the contact. If disabled (default), existing values remain unchanged even if the import file has blank fields.”

-
Import email plus phone duplicates Report an error
“Important: If you are importing contacts with both an email and a phone number, any duplicate in either field will cause that contact to be skipped.”
-
Import no duplicates Report an error
“Omnisend doesn't create duplicate contacts. When you import a file with contacts that already exist (matching email or phone number), the system updates their information instead.”
-
