I have been a fan of Newsletter Glue since they started. I use it to send out my weekly newsletter and I can use the same interface, I use on my website. The integration with other email services is fabulous. Their block-editor first approach makes any WordPress website a newsletter power-house, and you keep in charge of your archives, even if you change your Email marketing services. @lesley_sim and @fauzi keep close contact with the customer, especially if they need help. What a team!
