Reachkit vs Instantly

If I had to sum it up: Instantly is the bigger toolbox and the cheaper start, and Reachkit is the one that does more of the setup for you. Both let you connect as many of your own inboxes as you like (Instantly’s terms cap a workspace at 100 connected accounts), both set up done-for-you inboxes, and both have an official MCP server for AI assistants. The difference is what one plan covers, and how much you have to assemble and tune yourself. Everything here was checked in November 2026.

Pick Instantly if:

• You want AI agents that answer replies and book meetings for you.
• You run an agency and need white-label client portals.
• You want inbox placement tests, a CRM and website visitor tracking from the same vendor.
• You send a few hundred emails a day. At that volume Instantly costs well under Reachkit’s smallest plan.

Pick Reachkit if:

• You send around 1,200 emails a day and want one $597 plan with the 20 domains, 60 mailboxes, 20,000 lead credits a month, Unibox replies and unlimited teammates. On Instantly, replying and teammates start at $107, and inboxes and lead data are billed on their own.
• You’d rather describe a campaign in one sentence and get the sequence, the audience and Google or Microsoft inboxes set up for you.
• You want conservative sending defaults that protect your domains without tuning a settings page.

With Instantly, you assemble the stack yourself. You connect inboxes and set up DNS on your own domains (Instantly checks it with a domain test), turn on warmup for each account, buy lead credits or bring a list, and write the sequence or have Instantly AI draft the campaign. Instantly also sells done-for-you Google inboxes at $5 a month plus $15 a year per domain, delivered in 24 to 72 hours with DNS and warmup handled.

Reachkit keeps the campaign, the audience and the inboxes in one place. You can describe who you want to reach in one sentence on reachkit.ai before you even sign up, and the AI drafts the sequence and sizes a matching audience from 500M+ profiles. Once you pay, Reachkit sets up the domains your plan includes, 20 on Mega. It registers new lookalike domains just for sending, creates 3 Google Workspace or Microsoft 365 mailboxes on each, sets SPF, DKIM and DMARC, and starts warmup.

New inboxes still need time in both tools. Reachkit warms new mailboxes for about three weeks, then ramps them up. If you can’t wait that long, Instantly sells pre-warmed Google inboxes at $10 a month in batches of five, which is a real advantage when speed matters.

Instantly is built as modules you add as you grow. Sending lives on the Outreach plans: Growth at $47, Hypergrowth at $107 and Light Speed at $358 a month. Lead data, AI agents and website visitor identification run on Instantly Credits, a separate subscription from $9 to $1,700 a month. Inbox placement tests ($47 or $97) and done-for-you inboxes are each their own subscription too, while the CRM now comes with Hypergrowth and up.

The upside is real: you only pay for the modules you use, and the toolbox is large. The catch is the entry plan. Growth covers 5,000 emails a month, but it can’t reply from the Unibox, can’t add teammates and has no webhooks. Its 1,000 uploaded contacts are a fixed total, not a monthly allowance, that only frees up when you delete leads. For most teams I’d budget for Hypergrowth.

Reachkit has one plan per workspace with no seat fees, and its plans differ only in how much you send. Mega at $597 a month includes 20 domains with 60 mailboxes, warmup, Lead Finder with 20,000 credits a month, the Unibox with replies, the CRM, the REST API, webhooks and integrations, and unlimited teammates. There’s no smaller plan, so Instantly’s $47 entry is far lower if you only need a few inboxes.

Both tools give you the controls. The difference is what happens if you never touch them, which is how a lot of people run. That’s why I care more about defaults than settings.

Instantly recommends up to 30 campaign emails per inbox per day. Its slow ramp for new inboxes exists but is off by default. Open tracking is a per-campaign toggle that uses shared tracking domains unless you set your own, and Instantly itself advises against tracking the first email. Campaigns pause automatically if bounces pass 5% after 200 sends.

Warmup comes with every Instantly plan. Your inbox swaps mail with other Instantly customers’ inboxes, more than 1,000,000 by Instantly’s count, and its help center says every warmup email gets opened automatically. Instantly wants at least two weeks of it before an inbox joins a campaign.

Reachkit’s defaults lean conservative:

• New inboxes start at 3 campaign emails a day and add 3 a day until they reach 20.
• An AI writes every warmup email individually, and warmup runs on its own.
• Open tracking is off and there’s no click tracking, because tracking pixels are unreliable and can hurt spam scores.
• CSV imports are verified by default, and catch-all addresses are held for you to decide on.
• Unsubscribes are blocklisted across the workspace, and campaigns pause if bounces pass 5%.

Instantly does have tools Reachkit doesn’t: paid inbox placement tests, a Deliverability AI agent on Hypergrowth and up, and a premium warmup pool from $500 a month. If you want to measure placement inside the tool, that counts.

The reply is the hardest part of cold email, so look hard at where replies land and who can answer them. In Reachkit, replies land in the Unibox with one of 12 AI labels, such as Interested, Meeting Requested or Not Now. Anyone with Unibox access can answer from the inbox that sent the original, in the same thread, or schedule the reply for a better time. Inboxes running a live campaign are checked for replies about once a minute.

Instantly’s Unibox also collects replies and tags them with AI at no extra cost. The difference is who can answer there: replying inside it needs Hypergrowth, so on Growth you answer from each connected mailbox instead.

For agencies, Instantly is the better fit. Its white-label portal on Hypergrowth and up lets clients log in to your workspace on your own domain, without a subscription of their own. Reachkit is built for founders running their own outbound and has no white label. There you invite teammates and choose what each can see, feature by feature: inboxes, campaigns, the Unibox, settings and the CRM.

Instantly goes further on autonomous AI. Its AI Reply Agent drafts answers, handles objections and can book meetings through Calendly, on autopilot from Hypergrowth, at 5 credits per generated reply whether or not it’s sent. Its AI Sales Agent finds leads and writes and sends outreach at 5 credits per lead.

Reachkit’s AI drafts and you decide. It writes the campaign, finds the audience, writes your warmup and labels your replies. Today it doesn’t answer leads or book meetings for you.

Both have an official MCP server, the standard way AI assistants like Claude and ChatGPT work with other apps. Instantly’s exposes its full API and needs a plan with API access, from $47. Reachkit’s works on every plan with every tool, the Unibox included, signs in with your Reachkit account instead of an API key, and is built to show each email exactly as it will send and ask for your go before a campaign launches. Reachkit’s REST API and webhooks also come with every plan, while Instantly’s API starts at $47 and webhooks at $107.

Here’s the same sending volume priced in each tool, from each vendor’s public pricing page in November 2026, billed monthly. Assumptions: about 3 emails per new prospect, and one verified email per prospect, at 1 credit in Reachkit and Instantly’s published average of about 1.5 credits.

A founder starting out: 1 user, about 200 emails a day (about 4,300 a month) to about 1,400 new prospects, from 10 inboxes on 5 domains.

Instantly costs far less here, and about $163 if you bring your own list. Mega is Reachkit’s smallest plan, so at this volume about 50 of its mailboxes and most of its credits go unused. Instantly’s $47 Growth plan can’t reply from the Unibox and its 1,000 contacts run out in the first month, so Hypergrowth is the realistic plan.

A founder at full volume: 1 to 3 users, 1,200 emails a day from 60 inboxes on 20 domains, about 26,000 emails a month to about 8,700 new prospects.

Without lead data, Instantly is about $432 and stays cheaper. Instantly also advises up to 30 emails per inbox a day, and at that pace 40 inboxes on 8 domains cover the same volume: about $617 with lead data, $317 without. Hypergrowth’s 25,000 contacts fill in about three months, then each extra 25,000 is an $87 add-on; Mega stores 125,000. Annual billing lowers both plans: Mega to about $497.50 a month, Hypergrowth to $85.58.

Instantly is popular for good reasons. As of November 2026, it holds 4.8 out of 5 on G2 from more than 4,100 reviews, where ease of use is the top praise and many reviewers single out its support. On Trustpilot, where it has about 1,180 reviews, opinions are more mixed, though some of the one-star reviews there come from people who received spam sent through Instantly, not from customers.

The recurring complaints in 2026 are about how the product is packaged more than the sending itself:

• Replying gated to Hypergrowth, summed up in a Reddit thread titled “Avoid Using Instantly Growth Plan (you can’t reply to leads)”.
• Separate subscriptions and renewals people didn’t expect, under a no-refund policy.
• AI-first support that’s slow to reach a person, at least according to Trustpilot reviewers.

Reddit adds doubts about warmup, with one new subscriber writing that so far it seems “all it does is send and receive a bunch of random, spammy looking emails”. Instantly has fans there too, one of whom wrote that “Unlimited accounts on paid plans is great.” Threads asking for an Instantly alternative keep naming Smartlead and Lemlist, Lemlist mostly when you need LinkedIn steps.

On calls, people comparing the two describe the same tradeoff. A business owner who runs cold email outreach, testing Reachkit at the time, put it this way: “…I was not interested in something complicated like Instantly with the AI agent and all of that stuff. I was looking for something very simple to just get started with, and it has a very high level of deliverability.” A customer who runs an SEO business said: “I used to be with Instantly, and it was a bit of a mess for me… Why I switched was because Quinten held my hand through the whole process…”

I’d point you to Instantly in a few cases, and I mean it:

• You want AI to handle replies. Instantly’s Reply Agent drafts answers, handles objections and books meetings, and it can run on autopilot. Reachkit only labels replies today.
• You run an agency that needs white label. Instantly gives clients a portal on the agency’s own domain from Hypergrowth. Reachkit has client workspaces, not white label.
• You want everything from one vendor. Placement tests, a CRM with calling and SMS, website visitor identification and pre-warmed inboxes you can use this week all come from Instantly. Reachkit doesn’t do placement tests or visitor tracking.
• You send a few hundred emails a day. Hypergrowth with ten done-for-you inboxes is about $163 a month before lead data. Reachkit starts at $597.

If none of those are on your list, Reachkit gets you to the same campaigns with less to assemble and fewer plans to keep track of.

Moving over takes an afternoon if you own your inboxes, and about three weeks if you don’t. Do it in this order:

1. Export while your plan is active. Once you cancel, Instantly’s terms let it delete your data, with no obligation to keep any. Download your leads as CSV, plus your blocklist. Copy your sequences by hand or export them through Instantly’s API. Save any Unibox threads you need (the API can pull them in bulk), because threads on inboxes bought from Instantly can be deleted 24 hours after you cancel those inboxes.
2. Reconnect inboxes you own. Google Workspace and Microsoft 365 inboxes connect to Reachkit with a sign-in, and other providers over IMAP and SMTP. Reputation and warmup history live with the mailbox and domain, not the tool, so they come with you. Turn off Instantly’s warmup for those inboxes so they don’t warm in two places.
3. Replace done-for-you inboxes. Inboxes bought from Instantly can’t move. Use the domains your Reachkit plan includes or connect inboxes you set up yourself, let them warm for about three weeks, and keep Instantly running on the old ones until then.
4. Rebuild the campaign. Import the CSV (Reachkit verifies it on the way in), paste your sequence or let the AI draft a new one, and add your blocklist before the first send.

Instantly is a good product with a big toolbox. If you want AI agents answering your replies or white-label portals for clients, it’s the better pick today, and at a few hundred emails a day it’s also the cheaper one. What I hear on calls is usually simpler: people want to describe a campaign, get inboxes that are set up properly, and answer the replies without moving up a tier first. That’s what Reachkit is built for, and /build shows you the sequence and audience it drafts before you pay.
