Are you getting deluged with the constant questions? Mostly questions that you routinely have asked in prior emails to other customers? There are several options that you could use.
(1) Incorporate a Frequently Asked Questions section in your websites.
(2) Hire more first-level employees to handle customer questions and inquiries.
(3) My favorite, since I am a small business and cannot afford to hire more employees, is to utilize my Microsoft Outlook and create various signatures within File | Signatures section answering specific questions. I also create draft emails for when I have e-mails with attachments like my Web Development Workbook.
