Most possibly, Mandrill is ignoring the BCC headers and hence this error.
To solve this,
To
field rather than the Bcc
field and set X-MC-PreserveRecipients
to false.Bcc
address in the To
field but declare their type
as bcc
. Add "preserve_recipients": true
under the message section. The code given below is an example of implementing this solution.1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
{ "to":[ { "email":"to1.email@example.com", "name":"To Recipient Name", "type":"to" }, { "email":"bcc1.email.@example.com", "name":"BCC1 Recipient Name", "type":"bcc" }, { "email":"bcc2.email@example.com", "name":"BCC2 Recipient Name", "type":"bcc" } ] }
