Here are some suggestions for you. You will have more success.
1. Name the file correctly
As a label/podcast series, you often download the file and listen to it.
Soundcloud releases the original file with the download button. This always has the better quality.
And yes, original file. So you see all metadata. Here we are at point 2.
2. See what is in the metadata
The metadata can be seen as a label too. Better not brand your demo for a label. Good name example:
DJ XYZ – Promo Mix – Mai 2018
3. Do not send spam
Yes, you can detect spam fairly quickly, which is why we have set up an application form. It’s really annoying to get messages only with a SoundCloud URL.
4. Take your time
It’s much nicer to listen to a set knowing that the DJ has taken the time to write decent text.
Listening to promo sets is a lot of work, nice if this is appreciated.
5. Find out about the label
It’s certainly not appropriate if you send a Vocal Deep House podcast to a techno label.
6. How to send it
Each label has its own process, stick to it.
7. Accept the decision
It is often annoying to hear statements like, “You have no idea, my friends all love it”. It does not mean in a cancellation,
that it is not good enough. Often we are just full and do not want to generate a queue. Sometimes we also get up to 30 promo sets a week.
How do we want to upload everything? A refusal often simply means that the competition is better.
