I’m currently looking for an email marketing service for a mailing list of about 80,000 subscribers. I run an information product business in the fitness industry with a large number of customers buying our ebooks and online courses every day.

He also started the Direct Email Marketing Association to help stop unwanted email and prevent spam.  
For example, let’s say you have an ecommerce store and you’re running a sale. When you post about the sale on social media, not all your followers will see it.

I wondered, what are your thoughts on solutions like Mailigen, Vertical Response, Mad Mimi, and Campaign Monitor? I know there’s a never ending list of possible email software companies that you could compare, but these ones in particular interested me as they seem to offer many similar services to those that you mentioned. Have you come across them before, and if so would you advise using them over GetResponse?
However, with only a few simple templates and styles to choose from, the underwhelming visual impact of emails sent through ConvertKit make it a decidedly “function over form” option—that is, the back-end management and analytics that ConvertKit offers far outshines the experience of the end audience. So if sending beautiful or graphic-heavy emails is your highest priority, you should probably look elsewhere.
Many email newsletter software vendors offer transactional email support, which gives companies the ability to include promotional messages within the body of transactional emails. There are also software vendors that offer specialized transactional email marketing services, which include providing targeted and personalized transactional email messages and running specific marketing campaigns (such as customer referral programs).
