Orderly ‑ Order Notifier

I have contacted many times and reported that emails come as spam to customers, sometimes the emails do not arrive at all. At first they said they would help. Unfortunately I don't get a response anymore. I talked to another programmer about it and he knew where the problem was. Because you have the option to enter an email with the sender, it will be recognized as spam. Even if you enter their own email it will arrive as spam.
