It is undeniable that there is something more personal about receiving mail. It is also sometimes more effective and successful then phone or e-mail campaigns. People generally are more likely to actually completely examine and acknowledge information presented in a printed item they can hold. Postal marketing also eliminates the possibility of e-mails being disposed of in a spam folder and never getting a chance to be viewed. Having a postal marketing campaign will touch more clients when each address is verified to the targeted client you intend.
