Newsletter Ninja provides useful advice on building and maintaining a following for your newsletters. Perhaps the key message is you shouldn’t worry too much about subscriber numbers, but should instead concentrate on attracting the right sort of subscribers. Amen to that!
Much of the advice is fairly obvious, but worth reading. Some of the main recommendations make perfect sense, although I‘m unlikely to follow them with my own newsletters—not least because the very basic system I use for publishing my newsletters doesn’t provide the necessary functionality.
An interesting read if you have a newsletter, or are thinking of starting one.
