2013 Edition of America’s Fastest Growing Email Marketing Companies now available click here

A number of ESPs and Email Marketing Companies achieved a placement in the annual Inc. 5000 listing of America’s fastest growing companies.  Having trawled the listings and having looked up dozens of ESPS we have compiled a list of the fastest growing Email Service and Solution Providers in America.

“Interactive marketing has come a long way in a short time… and now represents 15% of all advertising spend,” wrote Shar VanBoskirk, vice president and principal analyst at Forrester Research, Inc. in her April 2011 report entitled “The Future Of Interactive Marketing.”   So it should be no surprise in that case to find so many marketing automation companies and ESP’s on the Inc.5000 list.

Some notable inclusions are iContact with an impressive 488% 3 year growth and Interspire with an incredible 504% three year growth. Heavyweights include ExactTarget with a turnover of $134.3 million, who have placed on the Inc. 5000 for 6 years running and Responsys at $94.1 million. There are of course ones to watch, including Emailvision with 126% 3 year growth and $56.7 million turnover. Listed on Inc. 500 as having 350 employee’s, those that follow the industry will know that they already exceed 600 employees with the recent acquisition of  the UK based SmartFocus.

“Interactive marketing and ExactTarget continue to experience rapid growth, as marketers move dollars from offline marketing channels and adopt our cutting-edge technology to connect with consumers in real time across email, mobile, social media and the Web,” said Scott Dorsey, ExactTarget’s chief executive officer and co-founder.

  1. It seems like iContact just sprang up out of nowhere. I remember suddenly seeing their commercials on TV and wondering who the heck was this new email marketing company.

  2. I have been quite skeptical of which among these companies. My friend told me to use Aweber because of the excellent service they provide. But iContact has a pretty good UI. Now I’m very confused.
