It’s easy to start campaigns, set follow-ups, and send emails straight from Gmail or Outlook, making these tools especially popular among Gmail users who benefit from seamless integration and tailored features.

But after a while, most users hit the same wall, Mailshake feels too basic for what they’re paying.

Many reviews say the same thing: it’s easy to use, but the design looks dated, features feel limited, and the price doesn’t match the value.

Why Consider an Alternative to Mailshake?

Mailshake is simple to set up and works well for small teams using Gmail or Outlook.

But once you start scaling, it can feel a bit limited. These limitations can hinder efficient sales processes for growing sales teams, making it harder to automate and manage complex workflows.

Here’s what most users notice before switching:

1. Too basic for the price

Even at $99/month, Mailshake lacks newer essentials like AI personalization, inbox rotation, or deliverability tracking, and is missing advanced features found in other platforms.

2. Outdated experience

The dashboard works but feels clunky. Managing templates or sequences takes more clicks than it should.

3. Hard to scale

You can only connect a few inboxes, which limits growth if you handle multiple clients or domains.

4. Inconsistent deliverability

Built-in warm-up helps, but you can't fully control DNS or rotation, so spam issues can still happen.

5. Support can be slow

Users report delays or small bugs that interrupt campaigns, a real problem if you send daily.

If you've ever thought, “Mailshake is fine, but I wish it did more,” you're not wrong.

That's why many teams are moving to modern tools that offer more power, control, and better deliverability for the same or lower cost.

Let’s look at the 5 best Mailshake alternatives in 2025 that actually make scaling easier.

5 Mailshake Alternatives for 2025

1. Salesforge – Best Mailshake Alternative for Cold Email and Deliverability 

Let’s start with the one that solves a lot of the problems you might’ve had with Mailshake, that is, Salesforge.

If you’ve been using Mailshake and feel like you’re stuck with limits, deliverability issues, or just paying too much as you grow, this tool is worth checking out. Salesforge offers robust sales automation and sales engagement features, making it easy to manage and scale your outreach campaigns across multiple channels.

Key features include automated follow ups, the ability to create multi-step email sequences, and advanced tools for streamlining your outreach efforts.

Why is Salesforge a Better Choice Than Mailshake?

Mailshake is simple and works fine when you’re just starting out.

But once you try to send more emails, manage more inboxes, or scale across LinkedIn and other channels, it gets frustrating fast.

That’s where Salesforge comes in. And it just makes things easier.

• No limits on mailboxes or senders

You don’t have to pay extra for each user.

You can add unlimited email accounts and LinkedIn senders. Salesforge also supports unlimited team members, so your whole team can collaborate on outreach without extra costs.

That means you can scale without getting punished for growing.

• Free warm-up that actually works

Every plan includes a warm-up through Warmforge, which uses real inboxes (not fake SMTP ones). So your emails land in your inbox, not spam.

• One inbox for all replies

Salesforge has something called Prime Box™. It pulls in replies from all your emails and LinkedIn in one place, simplifying managing campaigns across multiple channels.

Even if someone replies from a different email, you won’t miss it.

• Built-in deliverability tools

You can check things like SPF, DKIM, DMARC, inbox placement, and domain health, all without leaving the platform.

• Optional AI SDR (Agent Frank)

Don’t want to write or manage campaigns yourself? Agent Frank can do it for you.

But if you prefer to stay hands-on, you can run it yourself, totally up to you.

Salesforge Pricing (Quick Overview)

Salesforge offers three pricing plans tailored to different needs, including a dedicated email outreach plan:

• Pro Plan –

$40/month (billed yearly)

For solo users. You get 1,000 contacts, 5,000 emails per month, and 1 inbox with warm-up. Campaign reports are included to help you track performance.

• Growth Plan –

$80/month (billed yearly)

For growing teams. You get 10,000 contacts, 50,000 emails, unlimited inboxes, LinkedIn outreach, and Primebox. Campaign reports are available for detailed email engagement metrics.

• Agent Frank (AI SDR) –

$416/month (billed yearly)

This is the AI option. It handles your outreach for you, start to finish. Campaign reports are included for comprehensive campaign analysis.

No per-seat pricing. You only pay for what you need.

Mailshake vs Salesforge 

Should You Use Salesforge?

Here's when Salesforge makes more sense than Mailshake:

• You're using more than one inbox ‍
  ‍
• You want to send emails and LinkedIn messages ‍
  ‍
• You care about inbox placement and deliverability ‍
  ‍
• You're tired of paying per seat ‍
  ‍
• You don't want to deal with 4 different tools just to fix email issues

If Mailshake feels too limited or too expensive for what you're trying to do, Salesforge gives you more room to grow, better results, and fewer tools to manage. 

It just makes sense, especially if you're scaling fast or running outreach for clients.

👉 Let's move to the next one, Smartlead.ai, and see how it compares.

2. Smartlead.ai – A Mailshake Alternative with Inbox Rotation (But Comes With Tradeoffs)

If you’ve been exploring Mailshake alternatives, you’ve probably come across Smartlead.ai.

Smartlead.ai is known for its cold email automation capabilities and can also serve as a prospecting tool for outbound sales teams.

It’s known for offering unlimited inboxes, warm-up, and advanced automation, all at a pretty low price. It also integrates with Google Sheets for easy contact management.

But from what real users say, it’s not all smooth sailing.

Let me walk you through it.

Why is Smartlead better than Mailshake?

• Unlimited inboxes and warm-up included

Just like Mailshake's top plans, Smartlead lets you connect unlimited email accounts and run unlimited warm-up, even on their basic plan.

• Simple Clay integration

If you use Clay for lead data or CSV uploads, Smartlead makes it easy to connect and sync campaigns.

• API access and custom filters

Some users liked the API setup and being able to tag replies however they want, good for agencies or custom workflows.

• Dedicated IPs & dynamic sending

Smartlead offers SmartSender and SmartDelivery features to help rotate senders and land in inbox, though some users question the actual results.

• Affordable pricing

Many users said the price is fair for the features offered (starting at $39/month).

What Users Say Needs Work on Smartlead?

Even with all these features, a lot of people said Smartlead didn’t live up to the promise.

• Way too many bugs

Many users called it “buggy” or “frustrating.” 

Issues with campaign setup, adding variables, viewing replies, and deleting variants came up again and again.

• Slow or unhelpful support

Support replies can take a day or more. 

Some users said their bugs were ignored or blamed on email providers.

• Warm-up results not matching reality

Some said Smartlead showed “100% deliverability”, but their emails still went to spam or bounced. 

One reviewer said the warm-up pool might be hurting domains, not helping.

• No security controls

If you run a team, Smartlead doesn’t let you block staff from downloading lead lists or deleting data. 

That’s a big issue for agencies or large teams.

• Missing or limited analytics

One user pointed out you can only see results from 5 campaigns at a time, and even that data was incomplete.

Smartlead.ai Pricing

Smartlead offers 3 main plans:

• Basic Plan – $39/month

2,000 leads, 6,000 emails/month, unlimited inboxes and warm-up, plus API access.

• Pro Plan – $94/month

30,000 leads, 150,000 emails/month, ChatGPT4 integration, webhooks, and unlimited seats.

• Custom Plan – From $174/month

For agencies or large teams. Up to 12M leads and 60M emails/month, plus all features unlocked.

👉 No per-inbox fees. All plans include unlimited warm-up.

Mailshake vs Smartlead.ai: Key Differences

Should You Use Smartlead?

Smartlead might be a good Mailshake alternative if you’re a solo user, don’t need LinkedIn outreach, and want unlimited inboxes on a budget.

It may also appeal to lead generation agencies managing multiple campaigns who need outreach automation and premium deliverability.

But based on reviews:

• It’s not great for teams that care about security or need strong support ‍
  ‍
• The platform has a lot of bugs and missing features ‍
  ‍
• You might spend more time fixing issues than running outreach

Smartlead.ai sounds good, but in real use, it has too many issues right now for most teams.

If you want something more stable, with better support and full control, there are better Mailshake alternatives out there.

5 Smartlead Alternatives & Competitors in 2025

👉 Next up: Let’s compare Lemlist, known for its personalization and visual email outreach.

3. Lemlist – Mailshake Alternative With Multichannel Features (But Many User Complaints)

If you’re looking for a Mailshake alternative that offers multichannel campaigns, LinkedIn outreach, and email warm-up in one place, Lemlist might catch your eye.

Lemlist stands out for its ability to send personalized mass emails and include personalized images in outreach, helping users boost engagement. It also enables highly personalized outreach campaigns by allowing users to customize images, videos, and landing pages, creating a one-to-one feeling with prospects at scale.

But let me be honest with you, a lot of users say Lemlist looks better on the outside than it works on the inside.

Why is Lemlist a Mailshake alternative?

• Built-in multichannel features

Lemlist includes email, LinkedIn, and even WhatsApp messaging in higher-tier plans.

That’s something Mailshake doesn’t offer.

• Warm-up included (lemwarm)

You get access to their built-in warm-up tool, which is meant to help improve deliverability over time.

• Large lead database

You can pull leads from a 600M+ database and enrich them with job titles, phone numbers, and LinkedIn URLs.

What Users Struggle With Lemlist?

Despite the features, users reported serious issues:

• Customer support is slow and unhelpful

Many reviews mention delays of 10+ hours, poor issue resolution, and a lack of follow-up. 

Some even struggled to get refunds.

• Buggy and unstable

Users said the software breaks frequently. 

Weekly bugs, broken sending, or campaigns not running on time were common complaints.

• Clunky UI and poor user experience

Lemlist has been called "confusing" and "hard to figure out." 

Some users had to test things on dummy accounts just to understand how it works.

• Email tracking is misleading

Lemlist may count your own clicks or opens as engagement, which gives a false sense of performance.

• Drafts can't be edited after queuing

You can't go back to review or change a queued email, which is frustrating during live campaigns.

• Refund issues and billing concerns

Users reported being double-charged, blocked from their accounts after disputes, or stuck on plans they couldn't downgrade.

Lemlist Pricing

• Email Pro Plan – from $69/user/month

Includes automated email outreach, AI personalization, warm-up, and 3 inboxes per user.

• Multichannel Expert Plan – from $99/user/month

Adds LinkedIn, WhatsApp, in-app calling, and 5 inboxes per user.

• Enterprise Plan – Custom pricing

Designed for larger teams with extras like SSO, account managers, and advanced permissions.

Mailshake vs Lemlist: What’s Different?

Should You Pick Lemlist Over Mailshake?

Choose Lemlist only if you need multichannel outreach (like LinkedIn + WhatsApp) in one tool.

But if you care about:

• Stability
  ‍
• Clear tracking
  ‍
• Good customer support
  ‍
• A UI that doesn’t confuse you

...then it might not be the right move.

A lot of users switched after hitting too many bugs, bad support, and billing issues.

Next up: Let’s explore Apollo.io, a tool that adds data enrichment and CRM features to the mix.

4. Apollo.io – Feature-Rich but Frustrating Mailshake Alternative

If you’ve been using Mailshake and wish it came with a built-in B2B contact database, Apollo.io might catch your attention.

It combines lead data, automation, and outreach in one platform, leveraging intent data to improve targeting for email marketing and email campaigns. However, the user experience isn’t as smooth as it sounds.

Why is Apollo.io a Mailshake alternative?

• AI Features: 

The platform offers automation, AI-powered email writing, and workflow customization. 

Many users appreciated these, especially for the price.

• Wide Data Access: 

You get access to a massive B2B contact database and enrichment tools.

• Low Starting Price: 

Apollo is one of the most affordable platforms out there, especially for startups.

What’s Not Working Well in Apollo.io?

• No Real Customer Support: 

Users say support is mostly bots. 

Even when escalated to email, it’s slow and unhelpful. 

Some users never got replies at all.

• Bad Data Quality: 

Users reported outdated or missing company and contact data. 

One review even mentioned their own team was listed incorrectly.

• Unstable Features: 

The UI is slow and buggy. Uploading lists often fails. Some experienced platform downtime.

• Shady Billing Practices: 

Several users were auto-upgraded to new pricing without notice. Others lost discounts or were charged for unused LinkedIn seats. Refunds were hard to get.

• Poor CRM & Outreach Integration: 

The Salesforce integration was called a “nightmare.” Email deliverability is also a concern, with users being flagged by Google for spam sending.

Apollo.io Pricing 

• Free Plan: $0/mo – 100 credits, 2 sequences
  ‍
• Basic Plan: $59/mo per user – 2,500 credits, CRM integrations, enrichment
  ‍
• Professional Plan: $99/mo per user – 4,000 credits, workflows, dialer, AI tools
  ‍
• Organization Plan: $149/mo per user (min 3 users) – 6,000 credits, advanced security, international dialer

Plans are billed monthly (or discounted annually), but keep in mind: many users warned of unannounced changes.

Mailshake vs Apollo.io

Should You Pick Apollo.io Over Mailshake?

If you’re on a tight budget and want tons of features, Apollo might look tempting. 

But the real user experience tells another story, one filled with billing issues, bad data, poor support, and technical headaches.

For many users, Apollo.io became more trouble than it was worth. 

Unless you’re ready to deal with constant friction, you might want to stick with a more stable Mailshake alternative.

5. Reply.io – Multichannel Cold Outreach Tool With Too Many Red Flags

If you’re considering Reply.io as a Mailshake alternative, here’s what you need to know before jumping in.

Reply.io stands out as one of the leading sales engagement platforms, offering multichannel outreach with built-in LinkedIn automation features and integration with LinkedIn Sales Navigator for advanced prospecting and outreach.

It does let you send cold emails, LinkedIn messages, texts, and even make calls.

But the moment you look deeper, you’ll notice problems that are hard to ignore.

Let’s break it down clearly so you don’t get stuck with surprise charges, poor support, or broken features.

Why is Reply.io a better Mailshake alternative?

• Multichannel Outreach: 

You can reach people through email, LinkedIn, SMS, and phone, all from one place.

• Email Reporting: 

The reports are easy to read. 

You can quickly see how well a campaign is performing.

• Warm-up Tool: 

They offer unlimited email warm-up through their Mailtoaster feature (though users raised concerns about its effectiveness).

• Agency Use Case: 

Some users liked that it can handle multiple domains in one dashboard, helpful for lead gen agencies.

What’s Not Working Well in Reply.io?

• Interface Issues: 

Many found the interface clunky, confusing, and buggy, especially when using sequences. 

Sequences don’t always show where you expect them to, and editing them is frustrating.

• Poor Deliverability & Integration Problems: 

LinkedIn accounts often disconnect. Emails land in spam. 

HubSpot integration is buggy, and support struggles to help.

• Hidden & Unauthorized Charges: 

Several users reported being charged without consent or after cancellation. 

One user said they were locked into a $6K annual contract without notice.

• Lack of Support: 

Customer support is a major complaint, described as rude, unresponsive, or slow.

Many reported being ignored even after repeated emails.

• Inconsistent Features: 

Basic things like uploading contacts or viewing lists don’t work as expected. 

Users reported needing to contact support often just to get things functioning.

Reply.io Pricing 

• Email Volume Plan: Starts at $179/month (unlimited users, 10K contacts/month)
  ‍
• Multichannel Plan: Starts at $99/month per user (includes LinkedIn, SMS, calls)
  ‍
• AI SDR (Jason AI): Starts at $500/month (fully automated outreach agent)
  ‍
• Add-Ons: LinkedIn ($69/mo/account), SMS & Calls ($29/mo/account)

You’ll want to read the fine print, multiple users mentioned billing surprises and auto-renewals that were hard to cancel.

Mailshake vs Reply.io

Should You Pick Reply.io Over Mailshake?

If multichannel is your main priority, Reply.io does offer that. 

But it comes with serious risks, billing concerns, broken LinkedIn outreach, and poor support make it a tough tool to rely on. 

Most users ended up switching after constant bugs and frustrations.

For a Mailshake alternative you can trust long-term, you might want to look elsewhere.
