Hi Elijah,
Thanks for your reply.
I am not deleting any list via code. For each campaign I am adding one list and them schedule it. Lots of junk test list got created during development so I deleted them manually.
I just want to know, is there any limitation on the number of times a same contact can be added to the list(newly created), if the contact exists in other lists?
The nature of this error 400 is random, sometimes everything works well and sometimes it throws this error - Error 400: No contacts to send
I noticed that maximum time the error get poppep-up when I sent out same set of email IDs to the list and try to schedule it, during scheduling only the warning comes, rest everything works fine. But I am not sure what is the exact reason.
I am doing following things:
1) creating an array of contacts to addition to list
2) Add a new list to constant contact account
3) Using bulkAddContacts - add the contacts to list
4) Add the Campaign
5) If campaign is added successfully then schedule it - (here, Error 400: No contacts to send comes into picture )
If you want I can mail you the codes( my email is [REDACTED])
Thanks & Regards,
Vandana
