I have a custom CMS for my customers. That's because most of my clients are in a specific market (film industry) and need very specific tools.
But they also need to send newsletters. I did create some basic WYSIWYG HTML editor and managed to create a send out script with PHPMailer.
Everyone else seams to use MailChimp. Why? What are the reasons to use mail chimp over a custom made script?
- How does it affect reader's compatibility (and does it?)
- How does it affect spam blocking?
I've always thought sending e-mails through the original server was the way to go to avoid having a senders' mail not having the same reverse domain name.
Wouldn't it be better to simply create a clean inline css and send it out by connecting to the local SMTP server? No cost, no mail chimp monkey ad, etc.
Edit: This is not for the purposes of sending spam and most of my customers only have lists between 100 and 1500 recipients, they are all professional mails (film making industry). It is not about how to send 100K e-mails.
