Domain Name Forum - What email services do you use for transactional emails?

I tried several email services, but I always lacked online tools and advanced options to get a really high-quality service for my business. This was until I found this site https://mailazy.com/ on the Internet. On one of the forums for online business owners, I found references to this company, in the discussion of this provider there were many good comments from forum users and I decided to visit the site of this email provider of the company to find out more about their conditions. I've been using a business mailbox on their site for a few months now and I'm really happy with how it works.
