I don’t drink coffee, but the owner of a coffee plantation on the side of a volcano in Panama told me that it was one of the best ways to make coffee. I figure he would know.
My wife, who does love coffee, doesn’t use it simply because it only makes one small cup of coffee at a time, and she likes to start the day with a big cup. She acknowledges that the taste is superior.
I use Brevo as well. Free tier: 300 emails per day.
Very happy with them.
