Email marketing can be put pretty much on autopilot
Yes of course you will have to put some effort in to start off with but that work will be put to good use. A good example of this is that you can connect your blog to your newsletter so every time you post new content it automatically gets sent out to your subscribers without you having to do a thing.
You can also set up a series of newsletters that every subscriber gets. So yes once again it will take some time and effort to write up these newsletters and perhaps give them a tweak every now and then but this series will work for you for many years to come.
Your message goes straight to its destination
This is way cool and oh so different to other types of marketing. When you send an email it goes to your readers inbox and it sits there waiting for your reader to deal with it.
Think how different this is to social media where if your target audience is not sitting right there at the right moment you send out your posts? Chances are they will never see it
Emails are actionable
Yes no matter what your reader does with the email, even if it is unsubscribe, delete or mark as spam -they must DO something with it. Ok so hopefully it will be to open it up, read it and click through to your offer and purchase...
