Is there a limit on the amount of letters that can be submitted for mailing. We plan to use your service to send hundreds of letter in one day. Will this be possible?
One more thing to add we are using the Mailing Web Service API.
I read the Maximum number of pre-uploaded files: 20. Does this mean only 20 letter may be sent?
Please explain further how this works?
There is no limit on the amount of letters you can send.
The Upload File method is not related to the number of letters you can send.
The limit of pre uploaded files refers to the number of files you can upload using this method.
UploadFile() method allows users to pre-upload images, documents or templates to be used when sending letters and postcards through the PostalMethods service.
When sending multiple letters and postcards containing similar content, you may upload them first to the PostalMethods servers and reference them when executing a "Send" request.

You can send as many letters as you wish using the one of the various "Send" methods.
