That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 25 of the 26 other email sending services grade higher. It costs $72 a year. - You could not: Mail servers with a good name among inbox providers. - You could not: An API that other software can build on.
