The question may be sound stupid but I really don't get. Okay, it works great for those who can't or don't want to code. But, if you can code the sending emails is a piece of cake.
Maybe it's about delivery? But I saw that many emails sent from MailChimp went to my spam folder too.
Maybe it's about spamming? But if your user subscribes using your web site and you provide the Unsubscribe link it will be considered "not-spamming" email too.
Maybe it's about spamming because you are not allowed to send multiple emails at once? Who and how regulates this rule? GMass service does exactly the same.
Maybe it's about personalized emails? Come on. It's about sending a new piece of information to your subscribers and using their first name doesn't make emails "personal".
So, what's the real point to use such services except for the convenience the email can be collected?
UPD Clarification. I want to review the service from the coders' point of view.
UPD2 I don't ask you in the general sense - because I totally understand why such services may be convenient - the answer is to save your time, to allow you to focus on your business and others well-known "bla" excusing why ANY business exists. I'm asking because I found I can collect emails using just several lines of code - and if there is something that I desperately need and what the email marketing service can provide?
UPD3 I have a feeling people consider this question like an attack on their "favorite" tool - NOT AT ALL! What I'm trying to understand - if I really need it or not - that's it.
