Best AI SDR tools in 2026

11 AI SDR tools, the software that finds leads, writes and sends outreach and answers replies. They are ranked by how much of that work runs without a person, then by what you have to commit before the first email, from a free start up to a sales call. The first six run outbound on their own and the last five research and draft for reps who send. Prices read 28 October 2026 on each vendor's own site. Krabat is our product.

In the first 333 emails of the 101 accounts that sent at least that many between 11 August and 10 October 2026, the median account got 3 replies from people, and 39 accounts got at least one interested reply.
