Email newsletters is one of the most effective way to execute your marketing campaigns by reaching out directly to your subscribers who are basically your customers, readers, fans/followers or prospects. But the issue that many of us face is that, as the subscriber base grows or we want to send emails more frequently, the entire process can get a bit pricey when using services like Mailchimp, Campaign Monitor, Aweber, Signal, Constant Contact, GetResponse, LoopFuse, Sales-Push, Mad Mimi, Campaigner, Vertical Response, Benchmark Email, iContact, JangoMail, Boomerang and Ezine Director – unless our requirements can be fulfilled by their free plans.
