I have been using this service since 2015 when we first switched to WordPress because our emails were bouncing around like crazy. This is an amazing plugin that has saved us countless hours of frustration! All you need to do is add your own domain, point it at Amazon SES/AWS or use one of their providers (like Mailgun) and set up rules in wp-email-delivery. It's pretty easy. We didn't realize how good of a deal they had until recently -- about $5 per month if you pay yearly instead of monthly. The support is fantastic too -- always quick to respond and fix issues as necessary. If anyone needs assistance with sending emails through AWS, make sure you get a dedicated account manager from WPEmailDelivery. They are great!! Our team doesn't bounce emails anymore because W I can see all my emails in one place, which is very helpful. It is easy to set up the service and it is very quick and easy to use. The service is also very cheap. I have no complaints. It is a great service for a reasonable price. It is great for my business. It is very easy to use and keep track of all my emails. It is also very easy to set up, which is very helpful.
