Category: AI SDR built into Reply.io

Website: reply.io

Also known as: JasonAI(Reply.io), jasonai(reply.io), jason ai (replyio), jason ai (reply.io).

Overview

Jason AI is the AI SDR built directly into the Reply.io platform. It automates prospect research, email writing, and follow up sequences using Reply.io's existing infrastructure. Because it lives inside Reply.io, there is no integration to set up. You define your ideal customer profile and Jason handles the rest, from finding prospects to writing personalized first lines to scheduling follow ups. The quality of output is decent for high volume outreach but lacks the nuance that a skilled human SDR brings to strategic accounts. For teams already paying for Reply.io, Jason is included at no extra cost, making it an easy addition to test.

Pricing

Included with Reply.io paid plans starting at $49/user/mo.

Strengths

Weaknesses

Only available inside Reply.io, cannot be used with other sending platforms

How Jason AI (Reply.io) fits into a 2026 cold email stack

Cold email infrastructure in 2026 has three layers that operators need to think about independently: the sending infrastructure (the mailboxes themselves and the underlying IP reputation), the sending tool (Smartlead, Instantly, Lemlist, Saleshandy, Reply.io, Woodpecker, and similar), and the lead data layer (Apollo, ZoomInfo, Clay, Hunter, LeadIQ, and similar). Jason AI (Reply.io) sits in the ai sdr built into reply.io layer of that stack. Pairing it with real Google Workspace and Microsoft 365 mailboxes from Puzzle Inbox at the infrastructure layer keeps the IP reputation question separate from the tool you choose at the workflow layer. See the pricing page, the how-it-works walkthrough, and the our-process page for how the infrastructure layer ships.
