It is no secret that I am a fan of efax services. If you are thinking about switching to an efax service, you should check out FaxCompare, which compares the various efax services available.
The site has good information and I recommend it for anyone thinking about signing up for an efax service. The only downside that I see to the site is that it does not yet compare all of the efax services.
Thanks for the shoutout Brian. We are constantly updating our site and continually adding new vendors to our site to review. Thanks again for the blog post. 🙂
