This article is informative, but it does not offer distinguishing features between the services covered (other than mailchimp is free). You seemed to go to great lengths to say good things about each – although I’m sure each services has positive aspects. I would have benefited much more from a rating of some sort of the various features of each service, or at least the pros & cons of each.
When I started our Internet marketing company 20 years ago, it was just me and a dream. That dream was to grow and be the best. Today, we have 47 employees, all in-house, in Clifton Park, New York. The average employee has been with us for 6.49 years, and 10 of us have been here for more than 10 years bringing our combined work experience to 305 years! Compared to our Ninja army, I can’t believe that there’s a more experienced or tighter team of SEOs in the world. If you’re shopping around for an SEO company, know that IMN wins on experience and knowledge.
An aesthetically pleasing and informational website is an excellent anchor that can easily connect to other platforms like social networking pages and app downloads. It's also relatively simple to set up a blog within the website that uses well-written content with “keywords” an Internet user is likely to use when searching for a topic. For example, a company that wants to market its new sugar-free energy drink could create a blog that publishes one article per week that uses terms like “energy drink,” “sugar-free,” and “low-calorie” to attract users to the product website.
Works great. Does well what is says it should do. Using it to create multiple auto-responders during vacations and holidays, tailoring responses to different target audiences (different languages, referring senders to different back-up personnel according to their request, etc.). After trying the free version for a few minutes, I paid for the full version. Well worth it. Refreshing once an hour is OK. It would be nice to have control on the refresh rate, but it hasn't been a big issue for me.
Send new subscribers a “welcome” sequence. This is the message that you send to people right after they subscribe to your email list. It could contain a link to your lead magnet for an easy download, a thank you for subscribing, or maybe a call-to-action to check out your most popular blog posts. Every email list needs a welcome series: don’t miss this chance to “woo” your new subscribers and turn them into loyal fans!
