To make sure Gmail never filters as spam mail from a certain contact or domain:
To whitelist an entire domain (all mail from an address ending in "about.com", for example), just type the domain name or the domain name preceded by '@'. To whitelist "about.com", for instance, type "@about.com" (not including the quotation marks).
You do not have to create a separate filter for each address. Separate addresses with '|' in the From: field instead. To whitelist both "This email address is being protected from spambots. You need JavaScript enabled to view it." and "This email address is being protected from spambots. You need JavaScript enabled to view it.", enter "This email address is being protected from spambots. You need JavaScript enabled to view it.|This email address is being protected from spambots. You need JavaScript enabled to view it.", for example.
Giving Visitors What They Want
Web readers may be a difficult bunch, they may take a while to digest information and they may need convincing of every single point you deliver but they are essential. They can become long term, loyal customers, as long as you give them what they want.
Writing for the Internet is a different skill to writing for paper print or paper publications. Website readers digest smaller amounts of information in less time when compared to reading from paper.
This means that website content needs to be very well organised, concise, well formatted, and appealing. Throw in the proper use of search engine keywords, a powerful Call To Action (CTA), your Unique Selling Proposition (USP), and the natural scepticism of web users and it's easy to see why many website owners use professional content writers.
