Gmail is surely one of the top mail technologies currently available on the Internet because it offers large storage capacity, powerful spam filters and several other features that attract a considerable number of consumers. Obviously, all the users of the service customize it by their own needs using all kinds of tricks. But there are also numerous secrets that are able to improve the Gmail performance and enhance the functionality of the technology. Bill Kee, Associate Product Marketing Manager, tried to present 5 of them in a single post published on the official blog of the company.

First of all, the Mail Fetcher function allows you to customize the "From" field that represents your identity (the sender). If you didn't know, Mail Fetcher enables you to configure up to 5 POP3 accounts in order to receive the messages straight into the Gmail interface. Because of that, you can also send mail with these accounts so, depending on the configuration, your identity or the "From" field is also changed.

Another useful Gmail feature is the interoperability with Docs & Spreadsheets that helps you open the attachments without installing any application. This way, the files can be opened very fast directly from Gmail. In addition, you're able to check the Gmail inbox by adding a special gadget on your iGoogle page so you're not required to login into your account every time.

If you didn't hear about this Gmail ability, you can reply a mail by chat, meaning that you can communicate with another Google account owner without sending him a new mail. The function is displayed next to the 'Reply' and 'Forward' buttons and will instantly open the Gmail chat in order to talk with your contact.

The last and the most useful Gmail secret (although I already knew it) is the compatibility of the mail technology with the mobile devices connected to the Internet. "It's fast, it syncs with your online account, and it gives you virtually all of the same Gmail functionality like search, filters, and access to your whole archive of mail," the Google official wrote in the blog post.
