Best Email Marketing Software

The Best in Class Email Software

Whether you’re just entering the entrepreneurial world or you’ve lived here for some time, you’ll notice the term ”scalability” tossed around quite often. As your business grows, it needs to accommodate the increase in demand while maintaining the quality your brand provides.

At Infusionsoft, we understand the importance of scalibility and how integral it is in the success of your business. In order to achieve scalability, you need to market where your customers are – and today that’s email.

Implementing email marketing software is the first step on your road to becoming a scalable business. We’ve done some research and found that based on revenue and number of employees, businesses can be classified into four sizes (business classifications are based on our research and do not align with those of the SBA.):

  • Startup: 1-2 employees; <$100,00 in revenue 
  • Small Business: 2-25 employees; $100,000-$3 million in revenue
  • Medium Business: 25-500 employees; $3-60 million in revenue
  • Large Business: 500+ employees; $60+ million in revenue

Our research shows that most businesses within these categories share common ground in their email marketing software needs despite their nuances. Here are some suggestions for the best email marketing software based on the size of your business.

MailChimp’s marketing automation element allows you to send timely, relevant campaigns to your customers, and Inbox Inspection allows you to test your email design in the most-used email accounts and apps. This element also searches your content for spam indicators to ensure your email doesn’t trigger a spam filter.

But email marketing software is an investment. You’re investing in yourself and your business as well as in your current and potential customers. And just as it is with any investment, the time and money put in will seem inconsequential to the time and money saved.
