Hello, You would have to pay for experimenting with other forms of marketing if you want to refine your marketing methods. For example, if you want different banner ads designed for any of your products, you will have to pay the designing firm for both. On the other hand, with email marketing you can experiment with your emails by choosing the templates and inserting your desired details. You can change the color of buttons, headings of your emails, font of the text or anything else you want to check, to see which combination your customers are responding to. Is this right information about b2b promotional examples? I have gone through many related sources and also searched on the internet but didn't get the right solution. please help.
