AI outbound that waits for you

“Human in the loop” appears on many AI SDR sites. Ask a sharper question: can anything reach a buyer without a human clearing it? For most autonomous AI SDRs the default answer is yes; approval is optional.

Evaluation criteria

1. Approval is the default, not a setting.
2. You can edit, not just approve or reject.
3. Edits train the system (voice, timing, offer).
4. You keep your own sending domain, mailer and CRM.
5. There is an audit log and one pause switch.

The shortlist

• Rufus — approval gate on every email, post, connect and publish; covers marketing and sales; bring-your-own tools. Beta.
• Artisan — autonomous by default with a human-review option (per third-party reviews).
• Apollo — self-serve sequencing with manual steps; you write or approve the copy. Good if you mainly need data.

Disclosure: Vaitros makes Rufus. We list alternatives because the right tool depends on your volume and risk tolerance.
