Reachkit vs Mailshake

I’d pick Mailshake for a small sales team that wants email, calls and LinkedIn tasks in one sequence, and Reachkit for anyone sending from many inboxes without paying per seat. Both include unlimited warmup and sell done-for-you mailboxes, but Mailshake ties mailboxes to seats. I checked these facts in October 2026.

Pick Mailshake if:

• You want calls and LinkedIn tasks next to your emails, which its $99 plan adds with a built-in dialer.
• You send from one or two mailboxes and want SHAKEspeare, its AI copywriter, to draft sequences.
• Your CRM is Salesforce or Pipedrive, which Mailshake syncs natively and Reachkit doesn’t.

Pick Reachkit if:

• You’ll send from 10 or more inboxes and don’t want to buy seats to connect them.
• You want one sentence to become a drafted sequence, verified leads and Google or Microsoft inboxes, all set up for you.
• You want to try it first: Reachkit has a 30-day trial with no card, and Mailshake has none.

By default, Mailshake assumes you bring your own mailboxes and sells ready-made ones on the side, while Reachkit offers to build the sending side as part of your first campaign.

On Mailshake’s classic path, you buy domains and mailboxes, set SPF, DKIM and DMARC from its guides, connect each mailbox and turn on warmup. Its Ready to Use Mailboxes, sold since July 2025, skip that: Mailshake registers a lookalike domain, sets the DNS and adds five mailboxes for $12 a month. It doesn’t say which email provider runs them or who owns the domains.

Reachkit starts from the campaign: write one sentence about who you’re after, and the AI drafts a sequence and finds matching people in a database of 500M+ profiles. Then order Google Workspace or Microsoft 365 inboxes, and Reachkit registers new lookalike domains, configures SPF, DKIM and DMARC, creates the mailboxes with you as the named sender, photo included, and switches warmup on. Inboxes are $5 a month each and domains $15 a year.

Mailshake’s mailboxes are cheaper at $2.40 a month each, but always five to a domain; Reachkit’s checkout defaults to three per domain. I’d warm any new domain for at least three weeks either way.

Mailshake’s price is set by seats, and seats are also how you buy room for more mailboxes. Its pricing FAQ spells it out: “With each user you pay for, your team may connect 1 mail account. So you might choose to pay for 3 users but only have 1 person on your team so that you can connect 3 mail accounts.”

The plan cards and help center allow more on bigger plans, and disagree on the top one:

• Starter, $29 a month ($25 billed yearly): one mailbox and 1,500 sends a month.
• Email Outreach, $49 ($45): two mailboxes per seat.
• Sales Engagement, $99 ($85): 10 addresses on the plan card, up to five per user in the help center.
• Agency: priced by sales.

So seats follow mailboxes, not people. Deleting a mailbox even prompts you to drop a seat.

Reachkit prices the workspace instead: Growth at $39 a month ($29 yearly) or Scale from $99 ($79), both with unlimited inboxes and teammates. Limits sit on stored contacts and monthly emails, 5,000 and 15,000 on Growth.

That’s deliberate. At about 20 emails per inbox a day, volume comes from adding inboxes, and I don’t think each one should cost a seat. Domains and inboxes are separate line items; as one customer in the UK told me, “…you’re super transparent: you’re getting these domains and that’s what you’re paying for.”

Mailshake and Reachkit both send through your own provider with unlimited warmup, so the difference is in the defaults.

Mailshake gives you the parts:

• Warmup on its own network of addresses, which reply and rescue your mail from spam.
• Rotation across up to 50 addresses per campaign, from Email Outreach up.
• A suggested ramp from 20 emails a day per address in week one to 100 by week five, its advised maximum.
• Opens and clicks tracked on shared domains by default, unlimited list cleaning, and blacklist monitoring.

Reachkit sets them for you:

• A new inbox starts with 3 campaign emails a day and steps up by 3 daily until it reaches 20.
• Warmup switches on by itself, with each warmup message written by AI.
• Opens aren’t tracked by default and clicks never are, since pixels and tracked links can hurt placement.
• Uploaded lists get verified on import, and a campaign whose bounces pass 5% pauses itself.

The real gap is volume per inbox, 20 a day against Mailshake’s 100. I’d rather run five inboxes at 20 than one at 100, which is cheaper when inboxes don’t come with seats. In-app blacklist monitoring is one thing Mailshake has and Reachkit doesn’t.

Mailshake sorts replies by rules and Reachkit by AI, but the bigger daily difference is what it costs to add a person.

Mailshake’s Lead Catcher, from Email Outreach up, makes anyone who replies a lead by default, with optional rules on opens, clicks and replies. Leads can be assigned and marked won or lost, and follow-ups stop once someone is a lead.

Reachkit’s Unibox, on every plan, puts one of 12 AI labels on each reply, like Interested, Not Now or Wrong Person. Whichever tool you use, answer like a person: in my experience, most positive replies die when the response is a bare Calendly link.

In Mailshake each person is a seat, a User can add one mail account, and permissions can’t be customized. For agencies, Mailshake suggests a separate team per client, or its sales-led Agency Plan. Reachkit has no seat fees, so a client or a VA can join with access set per feature, though each client workspace needs its own plan.

Mailshake’s AI writes copy, and Reachkit’s works across the campaign, replies included. Neither answers leads for you.

Mailshake’s SHAKEspeare turns your website, a description and case studies into a six-email sequence, in English, and AI Sequence Suggestions drafts four or five follow-ups after your first email. Reachkit’s AI drafts the campaign from a sentence, finds and verifies the leads, writes the warmup and labels each reply, and campaigns stay drafts until someone launches them.

Mailshake’s REST API dates to 2017 and has webhooks for opens, clicks, replies, sends and new leads, but its docs say a campaign created through the API can’t be sent until someone finishes the campaign wizard in Mailshake’s app. There’s no official Mailshake MCP server as of October 2026, only third-party wrappers. (MCP lets assistants like Claude or ChatGPT use other apps.)

Reachkit’s MCP server works on all plans, the trial too, and it’s built to preview every email and ask before it launches a campaign. Its API, webhooks and CRM sync need Scale, from $99, while Mailshake syncs Salesforce, HubSpot and Pipedrive on its $49 plan. If you run on Salesforce or Pipedrive, that’s a real point for Mailshake.

Prices below come from each vendor’s public pricing page, October 2026, billed monthly and before tax. Mailshake’s mailboxes come five to a domain, so I used the nearest match, and I assumed they count toward seats like other mailboxes; its docs don’t say. Lead data assumes every new prospect comes from each tool’s database: 1 credit each in Reachkit, with extra credits at $25 per 1,000, and Mailshake’s $19 Data Finder unless Sales Engagement’s 2,500 included credits cover the month (its plan card doesn’t say they renew).

A founder starting out: 1 user with 10 inboxes on 5 domains, sending about 4,000 emails a month to roughly 1,500 new prospects.

The range reflects Mailshake’s 10-or-5 conflict and the credit question, and matching five domains adds at least $36. If bought mailboxes don’t count toward seats, Email Outreach with two packs and Data Finder costs $92, less than Reachkit. With your own inboxes and list, it’s $39 against $99 or more. Growth holds 5,000 contacts, so expect to prune finished campaigns from month four.

An agency or growing team: 3 users with 60 inboxes on 20 domains, sending about 25,000 emails a month to roughly 10,000 new prospects.

Only three of those seats are people. Mailshake’s Data Finder is sold as unlimited for $19 and its contact storage is unlimited, while Reachkit’s Scale plan stores 25,000, full after roughly two and a half months; the $239 tier, with 12,500 credits, brings Reachkit to about $564. Mailshake’s Agency plan might change its side, but only sales can say. Yearly billing cuts Reachkit to $29 or $79 a month and a Sales Engagement seat to $85 (see Reachkit pricing).

Mailshake reviews well, mostly for ease of use and support. On Trustpilot it scores 4.7 out of 5 across 100 reviews, and on G2 about 4.7 across more than 370 (October 2026), where G2’s AI summary names ease of use, quick setup and unlimited campaigns and contacts as the main benefits.

Users like:

• Support staff they know by name, weekly office hours and live training.
• Deliverability help: an October 2026 Trustpilot review calls it “…the best service we can find when it comes to deliverability…”
• A track record going back to 2015.

They complain about:

• Cost as mailboxes grow, as in this Reddit thread on alternatives.
• No trial, and a no-refund policy that two Trustpilot reviews, from 2023 and 2024, complain about.
• Rough edges: a February 2026 Trustpilot review says “…some flows take extra clicks and feel less intuitive than they should,” and G2’s summary lists bugs and limits with larger volumes of data.

Another Reddit poster spent about six months convinced Mailshake was the problem, switched to Smartlead, and found it “…did not fix our deliverability. Like, at all.” Placement mostly comes down to domains, volume and the list, which is why I judge a sending tool by what it does when you change nothing.

These are the cases where I’d tell you to choose Mailshake:

• Your outreach mixes email, phone and LinkedIn. Sales Engagement puts calls and LinkedIn tasks in one sequence with your emails, plus a power dialer, phone scripts and free calls to North American numbers. You do the LinkedIn steps by hand, but Mailshake schedules them. Reachkit is email only.
• You send from one or two mailboxes and want help with copy. Starter at $29 or Email Outreach at $49 gets a solo seller warmup, list cleaning and SHAKEspeare’s six-email drafts, and at that size seats cost you little.
• You want a long-standing tool with people to ask. Mailshake has been around since 2015, runs weekly office hours and live training, and its Salesforce, HubSpot and Pipedrive syncs are well established.

If you’re planning on 10 or more inboxes, or want the campaign, leads and Google or Microsoft inboxes set up in one place, Reachkit fits better.

If every mailbox you use is your own, you can move in a day; mailboxes bought from Mailshake add about three weeks while their replacements warm. In order:

1. Export before you cancel. Mailshake exports up to 20 campaigns at a time (prospects with stats, sent messages, list cleaning), and the unsubscribe list separately. There’s no one-click export of everything, and campaign data is deleted 30 days after the subscription ends. On a yearly plan, time the move for renewal; there are no refunds.
2. Reconnect mailboxes you own. Sign in once to connect each Google Workspace or Microsoft 365 mailbox; other providers connect over IMAP and SMTP. A mailbox’s reputation and warmup history stay with it and its domain. Turn off Mailshake’s warmup on those addresses first, since its own guide says to stick with one platform while warming.
3. Ask about bought mailboxes. Mailshake doesn’t document whether they or their domains can be transferred. If they can’t, replace them with Reachkit inboxes or mailboxes you set up yourself, and leave the Mailshake ones running until the new ones are warm.
4. Rebuild the campaign. Upload your prospect list, which Reachkit checks for bad addresses as it imports, then bring over the sequence or let the AI write a new draft. Load your unsubscribes into the blocklist before anything sends.

Mailshake is a solid, long-running tool with real people behind its support, and for a small team mixing email, calls and LinkedIn tasks from a couple of mailboxes, it’s a sensible pick. Where it pinches is growth: more inboxes means more seats, even when nobody new joins. Reachkit is built for the other shape of outbound, many inboxes each sending a modest amount, on one flat price, with inboxes set up for you at $5 each. If that’s your shape, run a campaign on the 30-day trial, no card needed, and compare.

For other options, I’ve compared Reachkit with Woodpecker, Reply.io and Saleshandy. For the budget side, see what to budget for beyond the subscription.
