Hi, when I used direct mail marketing, I entrusted it to my agent, who has been doing this for a long time. I can say that this is not an easy process, and you will have to hire a person who will do it. But, I believe that direct mail marketing is the best way to promote your business at the moment, so you need to master it and promote your business. However, I can advise you that before sending by mail, I advise you to read the information on the Internet about what items can be transported and in what quantity. When I was still engaged in direct mail marketing, I read articles about transportation rules by mail on this site -
