Multichannel sequencing with a capable AI SDR on top.

Reply.io runs multichannel outbound sequences across email, LinkedIn, calls, SMS and WhatsApp from one cadence, with reply detection, A/B testing, a unified inbox and meeting booking. Email deliverability is handled properly, with mailbox warm-up, inbox rotation, validation, and in-app purchase of pre-warmed domains and mailboxes added through 2026. Reply Data is its own contact database, built by scraping employment-oriented social networks with email formats inferred where not found. Jason is the AI SDR, now on its fourth major version, handling prospect research, message writing, reply handling and meeting booking, priced separately and substantially higher than the sequencing tiers. Recent additions include cloud calling with a power dialler and an agentic chat layer. There is a first-party MCP server launched in December 2025, with documentation and a dedicated endpoint.

Our verdict

A capable platform and the deliverability engineering is better than most at this price, with warm-up, rotation and in-app domain purchase all handled rather than assembled from separate subscriptions. Jason has matured into a credible AI SDR rather than a demo. The MCP server is real and documented. Three things we would want you to know before signing up, though, and they are more than nitpicks. There is a consistent and long-running pattern of complaints about cancellation: no in-app cancel button, email-only requests, charges continuing afterwards, and no refunds following a trial that bills immediately. That has appeared repeatedly over two years. Second, the compliance picture contradicts itself. The data processing agreement is genuinely good, with EU clauses and a UK IDTA, but there is no EU or UK hosting option, the security and GDPR pages are empty or missing, a live help article still cites the long-invalidated Privacy Shield, and the acceptable use policy bans scraped lists while the company sells scraped data with inferred emails. Diarise your renewal and do your own GDPR assessment.

Best for: Outbound teams who want email and LinkedIn in one sequence with solid deliverability tooling, and who are prepared to do their own compliance homework.
