Will DHL accept and ship a package that is not in DHL packaging?

So here’s the problem:
I have two packets to mail,
The DHL drop box had one envelope in it,
I could only mail one.

Now, what i’m shipping would fit in a manilla envelope (a folder with some info) and I want to get them mailed together. They need to go out ASAP…

So, if I put the info in a manilla envelope and checked the appropriate box that would equal what they would provide, would they ship it?

I do indeed have the correct shipping labels and everything, I could attach it to the envelope.

Any ideas?

Sure they will. I ship stuff all the time via DHL/FedEx and UPS in my own packages. Their packages are for convienence, not a requirement.
NOTE: The above does not apply to USPS.

Assuming that you attached a DHL airbill to the manila envelope, you’re fine.
