FeedBurner is a very popular RSS burning service these days. There are benefits to using FeedBurner to burn RSS feeds. First of all, the RSS Feed address will be fixed, even if your website domain name changes, you can update the relevant information directly on FeedBurner, original subscribers will still be able to read your site updates. Another benefit is that it eases the load on your server, because FeedBurner has helped you take the pressure from RSS feeds. However, not everyone likes to read using RSS, including myself. Because I think RSS reading is convenient and fast, but it always feels like something is missing. It's like reading a newspaper, you can't feel the smell of the website. Therefore, the ability to subscribe to mail should also be an important feature for blogs. Because email is much more popular than RSS. That's exactly what FeedBurner saw when it officially launched its own email subscription feature. I did a preliminary test and share it with you below.
