It is sold on volume-based pricing aimed at larger senders.

To get you started, here are 8 things to know about Mailkit, taken from its own pages and our grades.

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

Keep it

To replace Mailkit 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 $4,668 a year.

What you could make

  • Reports: 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.
  • Texts to thousands of numbers, registered with the carriers.
  • Reading the reports inbox providers send about your domain.
  • An API that other software can build on.
  • The depth: we grade its features B, which means it covers the whole job.

What this rests on. Mailkit’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.
