Keep Interspire Email Marketer, 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.
What you could make
- Forms: an app builder makes this well.
What you could not
- Newsletters sent to thousands of people that still reach the inbox.
- Email sent in volume that still reaches the inbox.
- Splitting visitors between versions and telling you which won.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Interspire Email Marketer’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
