The fastest-growing email marketing companies of America


The Inc. 500|5000 shows the 5000 fastest-growing, privately held companies in America. What are the 10 fastest-growing email marketing companies tin the Inc. 5000?

Email Expert went through them all and compiled a list of the top email marketing companies that rapidly grew from 2009 to 2012 AND earned their money with email services.

The Inc. 5000 of 2013

To be included in the 2013 Inc. 500|5000, a company had to be founded and generating revenue by March 31, 2009. The minimum revenue required for 2009 was $100,000. The list is ranked based on the three-year revenue growth percentage, comparing 2009 to 2012.

Ranking is based on revenue, which is not the same as profits. Marketo, for instance, had had no profits in 2010-2012. (bummer!) As we see in the filing of its IPO, Marketo even had a deficit of $82.2 million.

As the company is now among those ESPs on the stock market, Marketo won’t be on the Inc 5000 list next year. Only privately held companies are considered.

The top 10+ fastest-growing email marketing companies in America

To be included in the top 10+ list that Email Expert compiled, the companies needed to have a big portion of their revenue coming from the email channel. A good number of ESPs, email marketing and related companies achieved a placement in the annual Inc. 5000 listing of America’s fastest-growing companies.

The growth percentages are not only impressive but diverse. The actual 2013 revenue ranged from $22.2 million with 134 employees to $2.8 million with 20 employees. The minimum for inclusion was a revenue of $2 million in 2012. So these are some of the top email marketing companies from our total list, what growth is concerned.

The top fastest-growing email marketing companies 2013

10. Message SystemsRanked #3194 with 102% growth
11. DelivraRanked #4592 with 48% growth

Note: LivingSocial isn’t a true email marketing service provider (ESP definition) according to our definition, so I crossed it off the original list, despite its impressive top-growth position.

The Inc. 5000 is a list of the fastest-growing companies based in North America. I expect there are even more and maybe even faster -rowing email marketing companies in rapidly developing regions such as Europe, Asia and South America.

Many thanks to Andrew Bonar of EmailExpert for his work in compiling the original list.

      Hi Andrew, thanks forputting together the email top 10+ list.

      What I found to be particularly fascinating is to see the number of employees related to the revenues and growth from the Inc 500 list.

      Sailtru went from 2 to 79 people and 108K revenue to 8.1 million. That is an average of 25 extra employees per year and a result of 102.000 dollars revenue per employee.

      As super emailgeek that is the stuff I love to take in, haha. Looking forward to seeing your updates!
