RSS has been around for quite some time, and most if not all email marketing software will have RSS to email. Here are a few things to consider:
- Advanced Use: RSS to email is great and all but what about some additional use case like social sharing. That can also be a huge help to your blog by being able to automatically post to social networks.
- Email Customization: Being able to pull the RSS into a customized email is a lot better than just using standard templates, make sure you can keep your brand across all channels
Having the option to notify your subscribers every time you have new content is excellent, but most email marketing software providers offer a form or another. Make sure your choice has all the options and features you are looking for since this is only the starting point of email marketing.
