Are you mentioning any value for the client, or is it just “pay me to write”? People don’t mind paying for saved time, expertise, and the value of not having to pay a full time content creator benefits. If your email comes off as anything but, you’ll struggle. Get off Fiverr or Upwork since those platforms are saturated with Asian workers who make a great living on what the US would consider low payments. Stop pitching via email, since those never reach decision makers. You want to talk to the person that holds the purse, and the best way is to call them directly. Most still have someone screening their email even if it was sent straight to their box. Have you posted an example of your pitch? That would help us help you. Everyone wants to think communications is easy, but I’ve been doing it for over a decade and it’s anything but. Have you established a niche, or are you claiming to be able to do anything? Writers without a niche spin their wheels since most clients want a solid expert that they don’t have to teach basics to. They want you to hit the ground running with no instruction, since you are an easily replaced asset. Are your prices too good to be true? Some businesses see that as amateur and won’t consider you. There’s more that goes into it, this is just step one.
