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: 38 of the 38 other email verification and deliverability tools grade higher. It costs $828 a year. - You could make: Reports: an app builder makes this well. - You could not: A network of real inboxes that open and answer your emails.
