Editing Webmail (section)

== Rendering and compatibility ==
Email users may find the use of both a webmail client and a desktop client using the [[POP3]] protocol presents some difficulties. For example, email messages that are downloaded by the desktop client and are removed from the server will no longer be available on the webmail client. The user is limited to previewing messages using the web client before they are downloaded by the desktop email client. However, one may choose to leave the emails on the server, in which case this problem does not occur. The use of both a webmail client and a desktop client using the [[IMAP4]] protocol allows the contents of the mailbox to be consistently displayed in both the webmail and desktop clients and any action the user performs on messages in one interface will be reflected when the email is accessed via the other interface. There are significant differences in rendering capabilities for many popular webmail services such as [[Gmail]], [[Outlook.com]] and [[Yahoo! Mail]]. Due to the varying treatment of [[HTML]] tags, such as <style> and <head>, as well as [[CSS]] rendering inconsistencies, [[email marketing]] companies rely on older [[web development]] techniques to send [[cross-platform]] mail. This usually means a greater reliance on tables and inline stylesheets.

Microsoft Windows applications by default create email messages via [[MAPI]]. Several vendors produce tools to provide a MAPI interface to webmail.<ref>{{cite web|url=http://www.joonis.de/mapi4webmail|title=MAPI Extension for Webmail accounts - joonis.de|access-date=January 1, 2012|archive-date=August 26, 2021|archive-url=https://web.archive.org/web/20210826210647/https://order.shareit.com/product?productid=300431267|url-status=dead}}</ref><ref>[http://www.affixa.com/ Affixa] (Creating messages directly from Windows applications via MAPI)</ref>
