Reply.io: what it is, how it works and what it costs in 2026

Reply.io at a glance

Reply.io is a multichannel prospecting platform that puts email and LinkedIn automation inside the same sequence. Plans start at 59 dollars a month per user if you stay on email only, multichannel starts at 99 and the AI agent at 500. The trial lasts 14 days.

The figures published on its site and on its public profile today:

What is Reply.io and what is it for?

Reply.io started life as a cold email tool, the kind you plug into your inbox so it builds sequences with automatic follow-ups. Today it is something else. It is what the industry calls a sales engagement platform, which basically means the place where your whole prospecting operation lives: lists, sequences, emails, LinkedIn messages, calls and replies.

The difference from Instantly or Smartlead, which are very good specialists at what they do, is scope. Reply does not want you to leave its interface. You can open a conversation with a LinkedIn connection request, follow it with an email if nobody answers, drop a call into step five and close with an SMS. All of that with conditions like "if they open but do not reply, jump to the next channel". In practice it is close to building a small sales CRM without exporting anything anywhere.

Who it is for, plainly. It works well for sales teams of between three and twenty people who want to stop jumping between five tabs, for founders who prospect themselves and need a single dashboard, and for agencies running accounts for several clients from one workspace. If you are a solo operator who only sends cold email, there are cheaper and simpler ways to start. And if LinkedIn is your main channel, same story, though I get into that below.

One detail I value: it works the same with a free LinkedIn account as with Sales Navigator or Recruiter. You are not forced to pay the LinkedIn subscription to use the social side.

How Reply.io works under the hood

Sequences that decide on their own where to go next

The engine of the tool is conditional sequences. You draw the path and every step carries its own conditions and timings. If the prospect accepts the request, one route follows. If they have not accepted within four days, the system tries something else. If they reply, they leave the sequence and land in the unified inbox with a tag.

What gets the most use in practice is channel splitting. Plenty of people build a very short first email round, two or three touches, and move whoever does not answer over to LinkedIn. Others do the opposite, opening with a profile view and a like to warm the prospect up before writing. The tool lets you automate those warm-up steps, which is one of those things that sounds like a cheap trick and works more often than it should.

Jason AI, the artificial sales rep

The AI SDR plan leans on Jason, an agent the company presents as an SDR inside the software. It is supposed to learn what you sell, find the prospects that fit, write the messages, answer the replies and book meetings.

I want to be clear here, because I have spent far too long watching promises of this kind. An agent answering emails in your name makes sense on the first filter: it handles simple questions, asks for a slot in the calendar and rules out anyone with no interest. What I would not do is let it write the first sentence to a stranger without reviewing it. I have tested this with other tools and you can tell when a machine wrote a message. It is fine for filling in variables, for keeping the follow-up tidy and for not losing anyone along the way. For selling, not yet.

That said, having an agent that chases the people who do not answer and only stops when someone says yes is exactly the work nobody wants to do by hand. That part makes sense to me, and it is why the 500 dollar plan does not strike me as outrageous for someone who already has volume.

A database of more than a billion contacts

Reply bundles its own B2B database into the same package. The company talks about more than 1 billion contacts across 150 countries, 60 million company accounts, 220 million contacts in the United States alone and a bounce rate below 3 percent. The numbers are theirs and they sit in the same ballpark Apollo advertises, so treat them with the same distance you apply to the rest.

The interesting part is not the size, it is where the data lives. You can build a list with job title, industry and company size filters and launch it without leaving the campaign, or enrich the contacts you already have with the Chrome extension they use for LinkedIn, called Findy. For small teams that do not want to pay two subscriptions, one for data and one for sending, this saves real money every month. For anyone already paying for Apollo or Lusha, it is one more layer that overlaps.

Deliverability, warm-up and validation

The infrastructure side is the least visible and the one that matters most. Reply includes SPF, DKIM and DMARC checks, an inbox warmer that runs on Mailtoaster, address validation before sending and a custom domain for open tracking, so you do not mix your site domain with your sending domain.

You can also buy a new domain straight from the tool, starting at 6 dollars a year plus 5 per mailbox a month, or a pre-warmed one starting at 25 dollars a year plus 15 per mailbox. That is real convenience if you do not want to fight with DNS, though it costs more than setting it up yourself. If cold email is going to be your main channel, it is worth reading how to warm up a domain step by step first, because no tool saves you from a badly configured domain.

What it does to keep your LinkedIn account alive

The social side has three layers. The first is the daily limits you set yourself for connection requests and messages. The second is a monitor that watches your activity and eases off if it sees anything odd. And the third is the option to connect several LinkedIn accounts and spread the work across them, which is what agencies need.

It is worth saying without exaggeration. No tool in this category can promise you immunity, because LinkedIn is the one that decides and it changes the rules whenever it likes. In the reviews some people say they spent years on other platforms and saw not a single warning with this one, and some have run into trouble. The lesson is the usual one: conservative limits protect you more than the promises on the dashboard.

How much does Reply.io cost in 2026?

Reply does not have a single plan, it has four different doors and quite a few add-ons on top. The starting prices:

And on top of that, the add-ons almost nobody looks at when comparing and which change the final bill. The LinkedIn module costs 69 dollars a month per connected account, though the higher plans include one. Calls and SMS are 29 dollars a month per user. Each extra mailbox is 29 dollars a month. A new domain starts at 6 dollars a year plus 5 per mailbox a month, and a pre-warmed one at 25 plus 15. Email validations and AI credits are bought separately.

Translated into practice: if you are coming from comparing it with Waalaxy, which starts at 19 euros and covers LinkedIn and nothing else, the Reply price only makes sense if you are also going to use email. When you run the numbers, the usual mistake is comparing the 59 dollar email plan with a tool that also gives you LinkedIn and concluding Reply is cheaper. Add the social module before you decide.

That said, there is an advantage that does not show in the table and that an agency cares about a lot: users are unlimited on several plans. You do not pay per head, you pay for email volume, contacts and mailboxes. For a team of ten salespeople the difference from a per-seat model is significant.

Is there a free plan or trial on Reply.io?

There is no permanent free plan, but there is a 14-day trial that gives you access to the main features with no card required. For anyone who wants to understand how the platform feels before signing, fourteen days is enough if you use them well.

My advice is not to spend them wandering through the menus. Connect your inbox, build a three-step sequence with twenty real prospects, drop a LinkedIn step in the middle and watch two things: whether the replies land in the unified inbox in order, and whether the AI agent survives a short conversation without putting its foot in it. That will tell you if the product fits you. Sales results cannot be judged in two weeks, and anyone who promises otherwise is selling you smoke.

If what you want is to start without paying anything, Reply is not the cheapest door. Waalaxy has a free plan forever and lets you try all its features for 14 days, and if email is your channel, Instantly gives you 14 days free for new users with a more focused tool.

Reply.io vs Instantly, Smartlead and Waalaxy

These four tools overlap and split the market with fairly clear criteria. Side by side:

How I read it. If email is your only channel and what matters is sending a lot without landing in spam, Instantly and Smartlead are still better buys for the money, I compare them in detail in the Instantly.ai review and in the Smartlead review. Reply starts to win when you need both channels in the same sequence and do not want to stitch them together with Zapier. And if you are starting out and LinkedIn is your turf, Waalaxy costs a third of the price and does not force you into email you may not use yet. The detail is in what Waalaxy is and how it works.

What do the Reply.io reviews say?

On Trustpilot it scores 4.6 out of 5 from 264 reviews, and the most recent ones I read are from September 2026. On G2 the company publishes a 4.6 with 1,448 ratings, though I could not verify that figure first hand because the site blocks access. With the Trustpilot data, which I did read in full, there is more than enough to go on.

What the positive reviews repeat: support. It shows up in almost all of them, and not in passing. One business development lead with years of experience wrote that he had used around five prospecting platforms and that this was the best in terms of functionality and usability, with an interesting caveat: he had seen no warnings and no LinkedIn account issues, which gave him confidence to push volume. Another review from an agency says they compared Reply with Apollo and stayed here precisely because of the sequence logic and the ability to separate mailboxes and sender profiles when running several clients at once.

The negative reviews are just as specific and worth reading. One user complains that he could not find the button to cancel the subscription anywhere and ended up paying six months for a service he no longer used. Another, fairly angry, says he was marking contacts as finished and messages kept going out. And the most repeated complaint, no contest, is the learning curve: the tool has a lot of pieces and newcomers find it hard to see how they fit together. One review puts it well: I give it nine out of ten, but you have to put the time in.

That is the pattern of a powerful and somewhat dense tool. Nobody says it does not work. Plenty say you have to study how it works.

The drawbacks I see

The first is the curve. Reply has more surface area than any specialist and you pay for that in time. If you are coming from a simple email tool, your first week will feel lost. It is not a serious fault, but it rules out the "I will set it up in an afternoon" idea.

The second is the price once you add pieces. The LinkedIn module at 69 dollars a month per account and extra mailboxes at 29 mean the 99 dollar plan falls short quickly. The final bill for an agency with three social accounts and several mailboxes does not look like the number the comparison started with.

The third is cancellation. With a single user saying it I would not draw conclusions, but with the complaint that there is no button to cancel, it is worth knowing before signing. Ask how you cancel before you enter your card.

The fourth, and for me the most important, is transparency. The site has no team page and no decent about section, it does not publish its founding year, and everything I know about them comes from their own material or their Trustpilot profile, which places them in San Jose, California. It is not a product problem, but when I am about to connect my inbox and my LinkedIn account I need to know who is on the other side. It is the exact opposite of what other tools on this blog do, the ones that show their faces.

Verdict: is Reply.io worth it in 2026?

Reply.io is a good tool for anyone who needs both channels in one place, and a questionable buy for anyone who does not. If your team already sells through LinkedIn and email at the same time and is tired of stitching tools together with automations, the pitch fits and unlimited users make the per-head price work out well for mid-sized teams. The multichannel branch can be tried for 14 days without a card, so you can check it against your own prospects before deciding.

If email is your main channel, I would start with a cheaper and simpler specialist, such as Instantly or Smartlead, which do what Reply's 59 dollar plan does for less money. And if you are just starting out and LinkedIn is your turf, do not overthink it: Waalaxy costs a third, has a free plan and lets you try all its features for 14 days without spending anything. The detail is in what Waalaxy is and how it works.

The question Reply answers is a specific one: I want mail and social in the same sequence and I do not want to pay for two tools. If that sentence describes you, it is among the sensible options. If not, there are better and cheaper paths, and it is worth not paying for features you will not use.
