Bottom line
Mailscale now leads with agentic B2B cold email, pre-warmed mailboxes, and a 400 million contact file. Public rates are not printed. Plans are built on a sales call.
Stands out for: The live homepage sells an autonomous outbound agent that writes 125 email variants and reroutes sends when inbox placement drops, on top of mailbox provisioning.
Watch out for: The vendor does not publish a rate card. The homepage tells you to get a custom plan on a call, so there is no self-serve pricing.
Overview
Mailscale still provisions email accounts and domains, and the help centre documents mailbox, DNS, and billing workflows. The public site in 2026 leads as an agentic outreach platform: natural-language list building against 400 million B2B contacts, an AI copywriter trained on 200 million sends, pre-warmed mailboxes, self-healing deliverability, phone enrichment, and a reply agent.
The vendor publishes no pricing page. The homepage says the team will build your plan and pricing on a call. Older inbox-tier pages are gone. Treat current commercial terms as sales-quoted. This is outbound infrastructure and an agent, not an ATS or a generic ESP for newsletters.
Who it's for
Best for
- B2B teams that want mailboxes plus an outbound agent in one vendor
- Desks that need pre-warmed domains instead of a two-week warmup
- Staffing and sales teams that already close and lack prospecting time
- Buyers comparing mailbox infrastructure against Instantly or Smartlead
Not ideal for
- Teams that need a published per-inbox rate before talking to sales
- In-house recruiters who only need an ATS, not outbound email
