Permission marketing adds leverage to your online marketing campaigns. Once you are in front of your target market, you want to take every opportunity to stay there and continue to communicate with them time and time again. Permission marketing helps you achieve this, but it is a game of give and take. You give them a reason to give you permission to send them email—they give you the permission you are looking for; you take their personal information and they take your valuable content via your newsletter. There is a trade-off and the cycle continues.
Over time, you will gain more knowledge about your target market, which will empower you to provide them with a better overall experience in dealing with your company through better targeted promotions and better fulfillment of customer needs.
To summarize, permission marketing can return a much higher response rate over intrusive advertising; it can increase sales, build your brand, and help develop relationships with your target market; all while being cost-effective.
