Reachkit vs Reply.io

My short version: Reply.io fits when email is one of several channels, and Reachkit fits when cold email is the channel. Reply.io runs email, LinkedIn, calls and SMS from one sequence and sells an AI SDR on top; Reachkit sends email only and sets up the campaign, audience and inboxes in one place.

Reply.io’s terms don’t allow direct competitors to use it without permission, so I haven’t used it myself. Everything here about Reply.io comes from its public pricing page, help center, docs and user reviews, checked October 2026.

Pick Reply.io if:

• Your sequences mix email with LinkedIn steps, calls or SMS.
• You’d pay for an AI SDR to find prospects, write the emails and answer replies (Jason AI SDR, from $500 a month billed annually).
• Your sales team needs two-way sync with Salesforce or Pipedrive.

Pick Reachkit if:

• You want one price per workspace, with unlimited teammates.
• You’d like one sentence turned into a sequence and an audience, with Google or Microsoft inboxes set up for you in the same app.
• You want lead data included: 1,000 verified-lead credits a month from the $39 plan up, against Reply.io’s 50 data credits.

Both tools buy domains and set up Google or Microsoft inboxes for you; the difference is where you start. Reply.io is organized around mailboxes, lists and sequences, which you write yourself or draft with the AI sequence builder included on every plan.

Reply.io’s domains start at $6 a year and mailboxes cost $5 a month, with SPF, DKIM and DMARC set up and everything connected within 48 hours. New mailboxes go to MailToaster, Reply.io’s own warmup tool, with one warmup seat per mailbox on paid plans.

Reachkit runs the other way round. One sentence about who you’re targeting becomes a draft sequence and an audience count from 500M+ profiles, before any inbox exists. Order inboxes and Reachkit registers fresh lookalike domains, sets the SPF, DKIM and DMARC records, and connects Google Workspace or Microsoft 365 mailboxes that already show your name and photo, with warmup running.

Reply.io is ahead in two ways: domains from $6 a year against Reachkit’s $15, and pre-warmed bundles (a domain from $25 a year plus three mailboxes at $15 each a month) that can start sending right away, while Reachkit inboxes need at least three weeks of warmup. Whichever you pick, judge it on at least four weeks of real sending; three weeks in, you’ve mostly tested warmup.

Reply.io’s defaults let each inbox send far more, while Reachkit’s keep every inbox light and spread volume across more of them. Both ramp new inboxes slowly:

• Reply.io: 10 emails a day, adding 3 a day up to 100, under a cap of 400 per mailbox. A sending step stops for the day at 8% bounces after 200 sends.
• Reachkit: 3 campaign emails a day, adding 3 a day up to 20, follow-ups included. A campaign pauses past 5% bounces and alerts the team.

Reply.io’s defaults deserve credit: opens and clicks aren’t tracked unless you turn them on, new sequences send as plain text, and it adds Google Postmaster monitoring and a DNS health checker. Reachkit leans on defaults more than dashboards: AI-written warmup, open tracking off by default with no click tracking, verified CSV imports and a workspace-wide unsubscribe blocklist.

Twenty a day looks timid next to 100. I’d still add inboxes before pushing each one harder, because a burned domain costs every week you spent warming it.

Both tools pull replies into one inbox with AI labels. Reply.io’s Unified Inbox also holds LinkedIn replies and sorts threads into categories such as Interested or Not now, while Reachkit’s Unibox sorts email replies into 12 labels.

Out-of-office replies show the defaults at work: Reply.io resumes a paused contact after one fixed number of days for the whole account, while Reachkit holds follow-ups until the return date when the auto-reply gives one.

On teams, Reply.io’s help center lists one user on Email Volume below 10,000 active contacts and Multichannel is per user, though annual plans include onboarding with a customer success manager. Reachkit includes unlimited teammates, with access set per feature.

For agencies, Reply.io adds an agency dashboard and optional white label. Reachkit has neither, so each client gets a separate workspace on its own plan.

Reply.io has more AI, and its most autonomous piece, Jason AI SDR, is a separate plan. Every Reply.io plan includes an AI email assistant and sequence builder, AI variables, reply categorization and Agentic Chat, an in-app assistant that runs more than 30 actions from plain-language requests.

Reachkit keeps its AI to drafting and sorting: sequences and audiences from a sentence, warmup emails, reply labels. Replying to leads and booking meetings stay with you.

Both have an official MCP server (Model Context Protocol, how assistants like Claude and ChatGPT plug into outside software):

• Reply.io’s has 70 tools and comes with every plan, the trial included. It can start sequences, handle inbox threads and steer Jason AI SDR, but creating a sequence takes the REST API.
• Reachkit’s connects on any plan, the free trial included, and can assemble and launch a campaign from a chat. It’s built to show each email and ask before launching, and replying through an assistant needs Scale.

Reply.io’s REST API, webhooks, Zapier, Make, n8n and two-way CRM sync (Salesforce, HubSpot, Pipedrive, Copper) come with every plan. Reachkit’s API, webhooks, Zapier, n8n and one-way CRM sync (HubSpot, Zoho, Odoo, GoHighLevel) start on Scale at $99.

Multichannel outreach is what Reply.io is built around, and the clearest reason to choose it over email-only Reachkit. One Reply.io sequence can mix email with LinkedIn actions (connection requests, messages, InMails, voice messages), calls through a built-in dialer, SMS and WhatsApp tasks, with conditional branches.

On Email Volume, LinkedIn costs $69 a month per account and Calls & SMS $29 per account, plus a usage wallet for calls and texts. Multichannel bundles one LinkedIn account and calling per user at $99 a month ($89 billed annually).

Jason AI SDR is sold through a sales demo at $500 to $3,000 a month on annual billing ($800 to $5,000 monthly) for 1,000 to 10,000 active contacts. Point it at your website and it builds an offer, sources prospects from your ICP and intent signals, writes a researched message per contact, answers replies and books meetings, with your approval or on autopilot. Every tier includes unlimited users and mailboxes and done-for-you deliverability.

I’d weigh Jason against an SDR’s salary or an agency retainer, not a sending tool. If that’s your decision, read what running cold email in-house involves.

Reply.io’s Email Volume plan bills by active contacts, and a contact counts again in any month that sends it a follow-up, so a three-step sequence over two weeks bills about 1.4 to 1.5 times your new prospects. October 2026 list prices, billed monthly, before tax, from each vendor’s public pricing page, with Reply.io domains at their $6 starting price. Lead data assumes every new prospect’s email comes from the vendor’s own database: 1 credit each on Reachkit, with top-ups at $25 per 1,000 once the plan’s credits run out, and 2 credits each on Reply.io, bought in monthly packs.

Solo founder: 1,500 new prospects and about 4,000 emails a month, sent by one user from 10 inboxes on 5 domains (2,100 to 2,250 active contacts).

Reply.io’s $69 tier (2,000 contacts) only works if every follow-up lands in the same billing month. On Reachkit, Growth caps stored contacts at 5,000, which means deleting finished campaigns around month four or upgrading to Scale.

Agency or growing team: 10,000 new prospects and about 25,000 emails a month, sent by three users from 60 inboxes on 20 domains (14,000 to 15,000 active contacts).

The Reply.io data figures assume its credit packs can be combined, which the pricing page doesn’t confirm. Seats cost nothing extra on either side here, because Reply.io’s tiers from 10,000 contacts include unlimited users. Reachkit’s first Scale tier holds 25,000 contacts, which fills up in about two and a half months of new prospects; the $239 tier holds 60,000 and includes 12,500 credits a month, for $564 all in.

Reply.io’s G2 listing shows 4.6 out of 5 from 1,500+ reviews, and Capterra shows 4.6 from 95, checked October 2026. G2’s summary says users praise its ease of use and multichannel outreach, and one Reddit user wrote: “I kind of feel Reply.io is among the most easy to use…”

Cost for small teams is the complaint that recurs. G2’s pricing summary says most reviewers call it good value next to Outreach or Salesloft, but that pricing can feel steep for very small teams or solo founders, and a Capterra reviewer called the membership fee very high.

Many Reddit threads about Reply.io carry comments promoting rival tools, so I’d weigh them below the review sites.

I’d tell you to pick Reply.io in three cases:

• Your outreach runs on more than email. If LinkedIn requests, calls and texts belong in the same sequence as your emails, Reply.io runs them together, with branches between steps. Reachkit sends email only.
• You have the budget for a managed AI SDR. At $500 to $3,000 a month on annual billing, Jason AI SDR finds prospects, writes each message, answers replies and books meetings, with deliverability handled for you. Reachkit’s AI drafts and labels, and a person stays in charge.
• You run a larger sales team. Two-way sync with Salesforce, HubSpot, Pipedrive or Copper, single sign-on through Okta or Entra, a SOC 2 report from the Multichannel plan up and unlimited users from 10,000 active contacts all suit a sales org. Reachkit pushes positive replies one way to HubSpot, Zoho, Odoo or GoHighLevel, with no Salesforce option.

If none of that applies and your outbound is cold email, Reachkit is the shorter path.

The switch is mostly exporting and reconnecting; inboxes you bought through Reply.io are the slow part. Here’s the order I’d follow:

1. Export while your plan is active. Export contacts as CSV with “All fields” selected, or columns go missing. Sequences and threads have no one-click export that I could find, so copy steps by hand or pull them through the API, and save reports, since stats don’t transfer.
2. Bring over the inboxes on your own domains. Google and Microsoft mailboxes reconnect through a sign-in, anything else through IMAP and SMTP, with no cap and no charge. Reputation stays with the mailbox; take each one out of MailToaster once Reachkit’s warmup runs.
3. Plan around domains bought through Reply.io. Its help center says they aren’t tied to your subscription, but its product docs (not yet confirmed against the live app, they note) say cancelling or dropping to a free plan deletes Reply.io’s records of them immediately, and neither describes a way to transfer one out. Ask support about yours first, then warm replacement inboxes for about three weeks while Reply.io keeps sending.
4. Recreate the sequence. Upload the contact CSV, which Reachkit checks for bad addresses by default, paste in your old steps or ask the AI for a fresh draft, and load your do-not-contact list as a blocklist.
5. Cancel before the renewal date. Fees are non-refundable, with no grace period after a renewal charge. Email Volume and Multichannel cancel in the billing settings, AI SDR and Agency plans through support; data is deleted 30 days later unless you keep the $7 a month Data Storage plan.

Reply.io is a capable sales engagement platform, and if your outreach runs across email, LinkedIn and the phone, or you want an AI SDR to run it, it does things Reachkit doesn’t try to do. If your outbound is cold email, the job is narrower: properly configured inboxes, a clean list and replies you handle yourself, on a bill that doesn’t grow with each teammate.

That’s the job I built Reachkit for. A 30-day trial with no card is long enough to set it up next to Reply.io and see how it fits.
