Context paragraphs:
Metered reply mail: Metered reply mail, or MRM, is a type of mail in which a business sends pre-printed, self-addressed envelopes or postcards to customers, with postage prepaid on the envelopes or postcards with a postage meter.  It is thus similar to courtesy reply mail with a postage stamp already affixed.

Deep web: The deep web, invisible web, or hidden web are parts of the World Wide Web whose contents are not indexed by standard search engines for any reason.  The content is hidden behind HTML forms.  The opposite term to the deep web is the surface web, which is accessible to anyone using the Internet.  The deep web includes many very common uses such as web mail and online banking but it also includes services that users must pay for, and which is protected by a paywall, such as video on demand, some online magazines and newspapers, and many more.  Computer scientist Michael K. Bergman is credited with coining the term "deep web" in 2001 as a search indexing term.

Sales letter: A sales letter is a piece of direct mail which is designed to persuade the reader to purchase a particular product or service in the absence of a salesman.  It has been defined as "A form of direct mail in which an advertiser sends a letter to a potential customer."  It is distinct from other direct mail techniques, such as the distribution of leaflets and catalogues, as the sales letter typically sells a single product or product line, and further tends to be mainly textual as opposed to graphics-based.  It is typically used for products or services which, due to their price, are a considered purchase at medium or high value (typically tens to thousands of dollars).  A sales letter is often, but not exclusively, the last stage of the sales process before the customer places an order, and is designed to ensure that the prospect is committed to becoming a customer.

Mifepristone: Mifepristone, also known as RU-486, is a medication typically used with misoprostol to bring about an abortion.  This combination is more than 95% effective during the first 50 days of pregnancy.  It is also effective in the second trimester of pregnancy.  Effectiveness should be verified two weeks after use.  It is taken by mouth.

Mail cover: Mail cover is a law enforcement investigative technique in which the United States Postal Service, acting at the request of a law enforcement agency, records information from the outside of letters and parcels before they are delivered and then sends the information to the agency that requested it.  The Postal Service grants mail cover surveillance requests for about 30 days and may extend them for up to 120 days.

Freepost: Freepost is a postal service provided by various postal administrations, whereby a person sends mail without affixing postage, and the recipient pays the postage when collecting the mail.  Freepost differs from self-addressed stamped envelopes, courtesy reply mail, and metered reply mail in that the recipient of the freepost pays only for those items that are actually received, rather than for all that are distributed.

W3Perl: W3Perl is a free software logfile analyser, which can parse Web/FTP/Mail/CUPS/DHCP/SSH and Squid logfiles.  Most major web logfile formats are supported (Web : CLF/ECLF/NECLF on Unix, IIS/W3C on Microsoft ; Mail : Postfix/Sendmail/Exim), as well as split/compressed files.  "Page tagging" and counter are also supported if you do not have logfiles access.  The output is spread over HTML pages, with graphics and a sortable table.  Stats can be run from a single command line or from a web browser.

Courtesy reply mail: Courtesy reply mail, or CRM, is a type of mail in which a business sends pre-printed, self-addressed envelopes or postcards to customers, who then affix postage stamps to the envelopes or postcards and mail them back to the business.  Alternatively, the business can disseminate the envelopes or postcards with stamps already affixed, similarly to metered reply mail.

Women on Web: Women on Web (WoW) is an online abortion help service for countries where there is no access to "safe abortion service".  The abortion is done with Mifepristone and Misoprostol at home before the 9th week of pregnancy, the medicines are sent by mail under the supervision of a doctor.

DVD-by-mail: DVD-by-mail is a business model in which customers rent DVDs and Blu-rays of films and television shows, video games and VCDs, among other film media online, for delivery to the customer by mail.  Generally, all interaction between the renter and the rental company takes place through the company's website, using an e-commerce model.  Typically, a customer chooses from a list of film, show or game titles online and selects the titles she or he most wants to watch.  As a customer's requested titles become available, the company sends them out to the customer through the mail.  Once the customer has consumed the content, she or he sends the media back to the company via the mail.
