Watch: how Reply.io works
What Reply.io does
Reply.io is a sales engagement platform for outbound prospecting. Day to day, reps build multichannel sequences — cold email plus LinkedIn touches, calls, SMS, or WhatsApp — that adapt based on how prospects respond. A built-in B2B contact database (Reply claims access to over a billion contacts, used via credits) and a LinkedIn Chrome extension feed those sequences with leads, and a meeting scheduler and unified inbox handle what comes back.
A notable chunk of the product is email deliverability infrastructure: you can buy sending domains and Google or Microsoft mailboxes inside Reply, get DNS records configured automatically, warm mailboxes up through an automated peer network, and rotate them across campaigns to send volume safely. That removes several separate tools a cold-email operation would otherwise stitch together.
For teams that want less hands-on work, Jason — Reply's AI SDR agent — researches prospects, writes and personalizes emails, responds to replies, and books meetings, running in either autopilot or approval mode. Pricing scales from per-user email plans at $49/mo through multichannel plans at $89/user/mo up to AI SDR packages starting at $500/mo, with CRM integrations for Salesforce, HubSpot, and Pipedrive.
Key capabilities
Multichannel outreach sequences
Combines email, LinkedIn, calls, SMS, and WhatsApp in one conditional sequence that branches on replies and prospect actions rather than fixed scripts.
B2B contact database
Searches a large real-time contact database with intent signals to build prospect lists, plus a Chrome extension for pulling contacts from LinkedIn.
Deliverability infrastructure built in
Buy domains and mailboxes, auto-configure DNS, warm up sender reputation automatically, and rotate mailboxes across campaigns — all inside the platform.
Jason AI SDR
An AI agent that researches prospects, writes personalized outreach, handles replies, and books meetings, with autopilot and human-approval modes.
Meeting booking from sequences
Prospects book directly from outreach via a scheduler synced to your calendar, and AI-generated responses handle basic back-and-forth.
CRM and workflow integrations
Syncs with Salesforce, HubSpot, Pipedrive, and Gmail, with Zapier and an API for connecting other channels and tools.
Best for
- Sales teams running genuine outbound motions who want email, LinkedIn, and calling coordinated in one tool instead of three
- Cold-email operations that need the deliverability plumbing — domains, warmup, mailbox rotation — handled without extra subscriptions
- Lead generation and sales agencies managing outreach for multiple clients, which Reply supports with dedicated multi-workspace plans
- Small teams that want to test an AI SDR motion at a defined monthly price before hiring another rep
- Teams on Salesforce, HubSpot, or Pipedrive that need outreach activity synced back to the CRM
Worth knowing
- The advertised price is rarely the real price: LinkedIn automation is $69/mo per account and calls/SMS $29/mo per account on top of base plans, and data credits beyond the included 50/month cost extra
- The AI SDR starts at $500/mo for 1,000 active contacts and climbs quickly — model the per-meeting cost against just hiring or doing it manually
- Cold outreach carries real compliance obligations (CAN-SPAM, GDPR, and similar) and automated LinkedIn activity sits outside LinkedIn's terms of service — the risk is yours, not the vendor's
- Results depend on list quality and offer fit; automation amplifies a weak message rather than fixing it
- If your pipeline is mostly inbound or relationship-driven, a sequencing platform of this scope is more machinery than you need
How Reply.io compares
Outbound sequencers overlap on email and LinkedIn. The useful differences are channel range, how much sending infrastructure is built in, and whether an AI SDR is part of the offer. Reply.io has all three, priced as a base plan plus per-channel add-ons.
vs lemlist
lemlist runs a similar channel mix — email, LinkedIn, calls, SMS and WhatsApp — with a 650-million-contact database and intent agents, and prices those channels into its per-user Multichannel plan at $87 (annual). Reply.io adds domain and mailbox buying, warm-up and rotation plus the Jason AI SDR, but bills LinkedIn and calls per account on top. Choose lemlist for one all-in price; Reply.io for built-in sending infrastructure.
vs Smartlead
Smartlead is built for cold email at volume — unlimited mailboxes, warm-up, sender rotation and a master inbox — from $39 a month, priced by plan rather than per user. Reply.io adds LinkedIn, calls, SMS and WhatsApp to the same sequence. Choose Smartlead if deliverability across many mailboxes is the whole job; Reply.io if multichannel sequences matter to your team.
vs Salesforge
Salesforge is built around Agent Frank, an AI SDR that prospects, writes and books meetings, from $499 a month (annual) with email-infrastructure add-ons on top. Reply.io is a sequencing platform first, with Jason as an option from $500 a month. Choose Salesforge if the agent is the point; Reply.io if reps run sequences themselves and may add AI later.
vs Instantly
Instantly is a cold-email sequencer with unlimited sending accounts, warm-up and a unified inbox, from $37.60 a month (annual), with its lead database and CRM sold as add-ons. Reply.io costs more but puts LinkedIn, calls and SMS in the same sequence. Choose Instantly for low-cost email volume; Reply.io when one sequence has to span channels.
