The category's chart of price against score: https://toolgpa.com/charts/email-marketing ## Keep it, or make your own? **Keep it.** To replace Interspire Email Marketer you would be making newsletters sent to thousands of people that still reach the inbox. 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: 91 of the 102 other email marketing and newsletter tools grade higher. It costs $495, paid once. - You could make: Forms: an app builder makes this well. - You could not: Newsletters sent to thousands of people that still reach the inbox. - You could not: Email sent in volume that still reaches the inbox. - You could not: Splitting visitors between versions and telling you which won. - You could not: The depth: we grade its features B, which means it covers the whole job.
