If you send from more than two mailboxes, the cheaper Mailshake alternative is usually a tool that does not charge per mailbox. Smartlead and Saleshandy sell plans by sending volume and connect unlimited email accounts. Woodpecker bills per contacted prospect and lists email accounts as free.
At 20 mailboxes on monthly billing, at the time of writing, Mailshake's software fee is $198 or $396 a month, depending on which of its own documents you read. Smartlead Pro costs $94, Saleshandy Pro costs $99, and Woodpecker comes to about EUR 154 at the volume I model below.
If you run one or two mailboxes and your replies are fine, stay where you are. The price gap is small, and a new platform does not change who answers you.
Every price below is the one listed at the time of writing, on monthly billing, in USD unless it says EUR.
Disclosure: cold email and LinkedIn produce most of the meetings my team books, and we do no pure cold calling, so Mailshake's dialer gets no verdict from me and nothing below leans on phone figures.
Which Mailshake alternative fits your mailbox count?
Pick by the unit you pay for. Mailshake charges per user. Smartlead and Saleshandy charge for a sending tier. Woodpecker charges for the prospects you contact. The right tool is the one whose unit grows slowest in your setup.
- 1 to 2 mailboxes. Stay on Mailshake unless something else is broken. Starter covers 1 address and Email Outreach covers 2.
- 3 to 10 mailboxes. Smartlead Base or Saleshandy Starter, as long as your monthly sends stay under their 6,000 cap. This is where per-user pricing starts to hurt.
- Small lists with long sequences. Woodpecker. The bill follows prospects contacted, so extra follow-up steps inside one campaign do not add to the count. Adding the same person to a second campaign does.
- 20 mailboxes and up. The sending tier decides your price more than the mailbox count does. Plan on Smartlead Pro or Saleshandy Pro, and do the sends math first.
How does Mailshake actually bill, and how many mailboxes can it connect?
Mailshake bills per user, and each plan caps the email addresses one user can connect (Mailshake pricing).
| Plan | Monthly billing | Yearly billing, per month | Email addresses per the pricing page | What else the plan lists |
|---|---|---|---|---|
| Starter | $29 | $25 | 1 | 1,500 sends a month |
| Email Outreach | $49 | $45 | 2 | Unlimited sends, CRM integrations, unified inbox |
| Sales Engagement | $99 | $85 | 10 | Power dialer, 5 phone numbers, 2,500 Data Finder credits |
An Agency Plan sits behind a "Talk to Sales" button, so it has no public price.
Two add-ons sit on top, at the time of writing: Data Finder at $19 a month and Ready to Use Mailboxes at $12 a month. The pricing page does not say how many mailboxes that $12 buys.
The two mailbox caps that disagree
The pricing page and the help center disagree on Sales Engagement. The pricing page lists "10 email addresses per account" on Sales Engagement. Mailshake's own help article says that plan allows "up to five mail accounts" per user (Mailshake Help, Pricing explained).
The difference doubles your bill at scale:
- Pricing page reading (10 per seat): 20 mailboxes need 2 Sales Engagement seats.
- Help article reading (5 per seat): 20 mailboxes need 4 seats.
The help article has a second problem. Its Starter example reads "4 users X $299 = $897 / year". Four times $299 is $1,196. When a vendor's examples do not add up, trust the live pricing page over the help center, and get the mailbox cap for your plan from Mailshake in writing before you pay.
Billing terms that decide when you can leave
The same help article sets four rules:
- You are charged in advance, and billing dates cannot be changed.
- A subscription cannot be paused.
- There are no refunds, and no pro-rated refunds on cancellation.
- Mailshake erases all your campaign data 30 days after the subscription ends.
Put together, a missed renewal date costs you a full billing period. Waiting more than 30 days past expiry costs you your campaign history.
What does each mailbox cost on Mailshake versus Smartlead, Saleshandy and Woodpecker?
Start with software fees alone. To make volume caps comparable, I assume each mailbox sends 20 emails per sending day across 22 sending days. That is 440 sends per mailbox a month. I also assume a 4-step cold email sequence, so every prospect gets 4 emails:
- 5 mailboxes -> 2,200 sends and 550 prospects a month
- 10 mailboxes -> 4,400 sends and 1,100 prospects a month
- 20 mailboxes -> 8,800 sends and 2,200 prospects a month
The 20-mailbox line crosses the 6,000-send cap on both Smartlead Base and Saleshandy Starter, so that column moves both tools up a tier.
Vendor rules behind the table, at the time of writing:
- Smartlead: Base is $39 a month for 6,000 sends and 2,000 contacts, and Pro is $94 for 90,000 sends. Connecting more email accounts costs nothing on any plan, and the number is unlimited (Smartlead pricing).
- Saleshandy: Starter is $41 monthly ($34 billed yearly) for 6,000 sends and 2,000 active prospects, Pro is $99 monthly ($76 yearly), and email accounts are unlimited with no per-inbox fee (Saleshandy pricing).
- Woodpecker: from EUR 7 per 100 contacted prospects, excluding VAT, with unlimited email accounts listed as free. The same prospect added to 5 campaigns counts as 5 contacted prospects (Woodpecker pricing).
| Tool | Billing unit | 5 mailboxes | 10 mailboxes | 20 mailboxes |
|---|---|---|---|---|
| Mailshake, pricing page reading | Per user | $99 ($19.80 each) | $99 ($9.90 each) | $198 ($9.90 each) |
| Mailshake, help article reading | Per user | $99 ($19.80 each) | $198 ($19.80 each) | $396 ($19.80 each) |
| Smartlead | Sending tier | $39 Base ($7.80 each) | $39 Base ($3.90 each) | $94 Pro ($4.70 each) |
| Saleshandy | Sending tier | $41 Starter ($8.20 each) | $41 Starter ($4.10 each) | $99 Pro ($4.95 each) |
| Woodpecker | Contacted prospects | about EUR 38.50 (EUR 7.70 each) | about EUR 77 (EUR 7.70 each) | about EUR 154 (EUR 7.70 each) |
Woodpecker's cost per mailbox stays flat because mailboxes are not what you pay for. Contact twice as many people and the bill doubles, whatever your inbox count.
The other names on comparison lists
Most roundups also mention these tools. Their entry plans, from each vendor's own pricing page on monthly billing, at the time of writing:
| Tool | Entry plan, monthly billing | What it includes |
|---|---|---|
| Instantly | Growth, $47 a month (Instantly pricing) | Unlimited email accounts, with caps of 5,000 emails and 1,000 uploaded contacts per month |
| lemlist | Email, $69 a month (lemlist pricing) | Unlimited senders; price scales with the number of users |
| QuickMail | Starter, $49 a month (QuickMail pricing) | 5,000 emails a month, unlimited senders and users |
| Salesforge | Pro, $40 a month (Salesforge pricing) | 5,000 emails and 1,000 active contacts a month, unlimited mailboxes |
| Apollo | Free plan (Apollo pricing); paid tiers not priced here | Email campaigns from Gmail accounts only on the free tier |
Each of them sells by volume or by user, so the same rule applies: find your monthly sends first, then compare the tier that covers them. If you are choosing a platform from scratch, that is a separate question about picking a cold email platform. If Instantly and Apollo are your two finalists, they are lined up in Instantly vs Apollo, and if you really want inbox tracking, weigh the Yesware alternatives first.
Add the mailboxes themselves
Most pages stop at the software seat. If you buy ready-made mailboxes from the same vendor, at the time of writing:
| Tool | Ready-made mailbox fee | Domain fee | All-in at 20 mailboxes on 10 domains |
|---|---|---|---|
| Mailshake | $12 a month add-on, mailbox count not stated | None listed | $198 or $396 a month, plus the add-on |
| Smartlead | $4.5 a month per Google mailbox | $13 per domain a year | $184 a month, plus $130 a year |
| Saleshandy | From $2.99 a month per mailbox (annual mailbox plan) | $14 per domain a year | From $158.80 a month on the annual mailbox plan, plus $140 a year |
| Woodpecker | EUR 6 per Google or Microsoft address | None listed | About EUR 274, plus VAT |
Woodpecker also lists extra warm-ups at EUR 5 per email account, if you need more than the plan gives you.
The 10-domain assumption matches the footprint I describe in the deliverability section below. Mailboxes you already own on your own domains can move to any of these tools, so this table matters most when you are building from scratch.
The sender is one layer. Data, verification and a CRM sit beside it, and I break those down in the other layers of a cold email stack.
Will a different tool improve deliverability?
A different tool will not change the rules that matter most, because they live in your domain and DNS records.
| Mailbox provider | Who it applies to | What you need |
|---|---|---|
| Gmail | All senders | SPF or DKIM, plus TLS (Google Workspace Admin Help) |
| Gmail | About 5,000+ messages a day to personal Gmail accounts | SPF and DKIM, DMARC (a monitoring-only policy, p=none, is enough), a From domain that aligns with one of the two, spam rate below 0.10% and never reaching 0.30%, one-click unsubscribe on marketing mail, unsubscribes processed within 48 hours (Google bulk sender guidelines) |
| Outlook.com consumer domains | Over 5,000 emails daily | SPF and DKIM must pass, DMARC at least p=none and aligned; non-compliant mail is rejected with the error code 550 5.7.515 (Microsoft Defender for Office 365 blog, "Outlook's new requirements for high-volume senders") |
| Yahoo | Senders to Yahoo addresses | Yahoo publishes its own sender best practices |
Two details catch teams out. Gmail's bulk sender status has no expiration date, so one heavy day keeps you on the stricter rules for good. And Microsoft says plainly that authentication is tied to your domain even when someone else sends for you. A new platform sends from the same domains with the same records.
The foundations I insist on, in order:
- Put SPF, DKIM and DMARC records on every domain before any volume goes out.
- Give each new mailbox 10 to 14 days of warm-up, minimum, ahead of its first prospect email. If you are buying fresh mailboxes for the switch, read how long to warm up a new domain before you set a migration date.
- I budget 20 to 40 mailboxes spread over 10 to 20 domains for a typical cold email program, and more for bigger companies.
On client campaigns my team runs dedicated sending IPs, separate even across different domains, so a client can sit on 10 to 20 IPs, and we handle the domains, authentication records, warm-up and monitoring. None of that came with a sending tool. It is work on the infrastructure under the tool.
Treat published tool shoot-outs with caution. Per Gmail Help, Google does not track open rates, so low opens say little about whether mail is delivered (Gmail Help). Open-rate shoot-outs run by vendors on different lists, from different senders, prove almost nothing about the tool.
What does a setup with dozens of mailboxes look like in practice?
Take a program above the 20 to 40 mailbox range I plan for: 50 email accounts.
At that size the billing unit starts to matter. On Mailshake, 50 mailboxes means 5 Sales Engagement seats on the pricing page reading or 10 on the help article reading. That is $495 or $990 a month in software, before a single mailbox is bought.
Still, the tool bill is the smallest decision in a setup like this. The domains, records and warm-up are the real work. Those costs grow with you. Volume comes last. A funnel that fails at 1,000 sends will fail at 100,000, and a cheaper seat does not change that.
Who pays matters too. When my team runs outbound for a client, the client pays tools, sending domains, mailboxes and data directly, separate from our fee. That keeps the stack the client's asset, and it means we have no reason to push one platform over another.
If you are deciding whether to run all of this in-house, count what running cold email yourself really costs first.
When should you not switch away from Mailshake?
Weak reply rates rarely come from the platform. Copy cannot fix a bad list or a weak sender, and a new dashboard cannot either. Which CRM, automation or AI platform you pay for makes no difference to prospects. They see one email from one sender.
| What you see | Switch or stay | What to do first |
|---|---|---|
| 1 or 2 mailboxes, replies are fine | Stay | Nothing. The saving is a few dollars a month |
| Bounces keep climbing | Stay for now | Fix the list; bounces follow you to any tool |
| Replies dropped after you raised volume | Stay for now | Check sender health: records, spam rate, warm-up on any new mailboxes |
| Replies are near zero, whatever your open numbers say | Stay | Fix the offer and the sender profile ahead of any copy edits |
| Seat bill grows every time you add a mailbox | Switch | Price your next 6 months at the tier your sends require |
| Renewal date is close | Decide after export | Export first, then choose with time to spare |
The bounce row deserves a second look. A bad list bounces the same way on every platform, which is why the list deserves a look before anyone touches settings.
Move the same offer, the same list and the same sender profile onto a popular automation platform and you usually get the same silence on a new dashboard, plus weeks of setup.
Prospects check the sender's profile, website and proof before they answer, and silence after a failed check looks exactly like weak copy. If a buyer cannot tell who you are or what you have proven, a better sender tool will not make them reply. Fix the profile, the offer and the proof first. Then compare tools.
The migration timing rule
If the table says switch, Mailshake's billing terms set the order:
- Write down your renewal date. Since there are no refunds and no pausing, that date is your real deadline.
- At least 3 weeks before it, export campaigns, replies, unsubscribes and lead status.
- Connect your existing, already warmed mailboxes to the new tool. Their standing belongs to the mailbox and its domain. The sending tool does not own it.
- If you are adding fresh mailboxes, buy them now so they finish 10 to 14 days of warm-up before you need them.
- Run the new tool alongside Mailshake until your sequences finish, then cancel before the renewal date.
- Never plan to export after expiry.
Gmail's own help page says user spam reports lower your domain's reputation over time. SMTP.com explains that Gmail's score follows the domain in your From address. The sending IP is only part of it.
Which compliance basics move with you whatever tool you pick?
If you email people in the United States, CAN-SPAM applies whichever platform you use. Under CAN-SPAM, B2B email is not exempt.
- Honor an opt-out within 10 business days.
- Your unsubscribe link must keep working for 30 days or longer after each send.
- Include a valid physical postal address.
- A single violating email can cost up to $53,088 in fines.
- You cannot contract your legal responsibility away to the tool or the agency sending for you; both can be held responsible.
That covers US law only. Other countries have their own rules, and none of them care which sender software you chose. When you migrate, carry your unsubscribe list over first, before any campaign goes live. This is not legal advice.
Thinking about switching sending tools and doubting it will change your replies? Book a call and I will look at your setup with you.
Questions people ask before leaving Mailshake
Does Mailshake offer a free trial?
No free trial is offered. The pricing page states that payment is collected up front, and you cancel before the renewal date to avoid the next charge. To test before paying, Saleshandy lists a 7-day trial with no credit card, and Woodpecker lists a 14-day free trial. Smartlead's pricing page lists no lock-in contracts.
Is there a Mailshake lifetime deal?
The pricing page lists none at the time of writing: plans are billed monthly or yearly. So the money question is the monthly fee and the billing rules above. There is no one-time purchase.
Which tool suits agencies better than Mailshake?
Look at the per-client fee. On Pro and up, Smartlead sells white-labeling as an add-on at $29 a month for each client workspace, so 8 clients adds $232 a month. Woodpecker's Agency Panel costs EUR 27 per active client, plus EUR 5 per active client for white label, so 8 clients adds EUR 256. Mailshake's Agency Plan has no public price.
Do I need Mailshake's phone dialer?
Only if your reps actually phone prospects from the platform. A team that books meetings by email alone and buys the $99 Sales Engagement seat only for its mailbox allowance pays for a dialer it never opens. In that case a tool priced by sends usually fits better, because Email Outreach connects only 2 addresses.
What happens when I go over a plan limit on Woodpecker or Smartlead?
On Woodpecker, a campaign stops sending to new prospects once you pass your plan limit, and the plan does not upgrade itself; you upgrade or wait for the limit to renew. Smartlead counts contacts and email sends as separate counters, so you can hit one before the other.
