By the end, you will know which tool fits your sales process.
What is Instantly?
Instantly is a cold email outreach platform built for high-volume sending.
It lets you connect unlimited email accounts on every paid plan.
Those accounts share the load through inbox rotation, so no single domain burns out.
The platform also bundles a lead finder, a unified inbox, and campaign analytics.
Instantly CRM sits inside the same account as a separate module.
Most businesses pick it to send thousands of cold emails without landing in spam folders.
Here is a walkthrough of how the platform works in practice.
🏆 Winner: Instantly
Connect unlimited email accounts and rotate sends across them. The built-in lead finder pulls contact details without a second tool.
Instantly Pricing
Instantly runs four tiers. Here is what each one costs.
| Plan | Price | Best For |
|---|---|---|
| Growth | $30/month | Solo founders testing cold email |
| Hypergrowth | $77.60/month | Small business sales teams |
| Light Speed | $286.30/month | Agencies running multiple campaigns |
| Enterprise | Custom | Large outbound departments |
Pricing verified August 2026.
Free trial: Yes. Instantly offers a 14-day free trial so you can test the campaign builder first.
Money-back guarantee: No published refund window. Cancel before renewal to avoid the next charge.
📌 Note: Sending seats and lead credits are billed separately. The Growth plan covers unlimited email warmups and unlimited email accounts, but lead credits and the CRM module are priced as add ons. A Hyper CRM tier adds advanced features and multi-channel support.
⚠️ Pricing conflict: Our research notes list Instantly CRM at $97 per month for unlimited seats and access to all the features. That figure is not in the sending plans above, which come from our own pricing records. Check the vendor page before you buy, since the CRM module bills separately from campaigns.
Key Benefits of Instantly
Here is what makes Instantly worth a look:
- Unlimited sending accounts: Every paid tier supports unlimited email accounts. Inbox rotation spreads volume so you avoid spam filters.
- Built-in B2B lead finder: The integrated database holds over 450 million contacts. Multiple filters let you narrow by role, industry, and company size.
- Unibox for every mailbox: Replies from multiple email accounts land in one unified inbox. That single place keeps your sales team from missing warm replies.
- Website visitor tracking: A tracking pixel identifies US-based visitors. Those turn into actionable growth leads for your next campaign.
- AI personalization: The platform analyzes each prospect and drafts relevant openers from company insights. It cuts the repetitive tasks out of writing personalized messages.
- Campaign analytics: Reporting tracks opens, replies, and bounce rates over time. You can fine tune subject lines before scaling a winner.

What is Mailshake?
Mailshake is a sales engagement tool built for cold outreach.
It helps sales reps send personalized cold emails from their own email provider.
Sending from your existing inbox is what protects deliverability here.
The platform then layers LinkedIn messages and cold calling on top of email.
An email domain setup assistant walks you through DNS records during onboarding.
Mailshake has been used by over 49,000 companies worldwide.
The review below shows the dashboard and campaign setup.
🥈 Runner Up: Mailshake
Runs email, LinkedIn outreach, and phone calls from one dashboard. The power phone dialer folds cold calling into the same sequence.
Mailshake Pricing
Mailshake bills per user. Here is what our pricing records show.
| Plan | Price | Best For |
|---|---|---|
| Starter | $25/month | Solo sales representatives |
| Email Outreach | $45/month | Growing teams running email campaigns |
Pricing verified August 2026.
Free trial: No. Mailshake asks you to pay upfront, which is a real gap next to a 14-day free trial.
Money-back guarantee: A 30-day refund window is offered on annual billing.
📌 Note: Prices above are the annual rate per seat. Monthly billing runs higher, so costs climb as your sales team grows.
⚠️ Pricing conflict: Our research notes describe a third tier, the Sales Engagement plan, at $85 per user annually or $99 monthly. It carries LinkedIn automation and unlimited free dialer minutes. That tier is absent from the pricing records above, so confirm the current lineup on the vendor site.
Key Benefits of Mailshake
Here is where Mailshake earns its place:
- Sends from your own inbox: You connect an existing email provider instead of renting shared servers. Prospect inboxes see a familiar sending domain.
- Multichannel sequences: One campaign can mix email, LinkedIn connection requests, and phone calls. That reach suits established teams working named accounts.
- SHAKEspeare AI writer: The AI drafts email copy and subject lines from your campaign goal. It speeds up writing without removing your edits.
- Lead Catcher: The dashboard surfaces your most engaged prospects first. Sales reps then spend time on leads that convert.
- Power phone dialer: Cold calling runs inside the same sequence as email. No switching between multiple different tools mid-task.
- CRM sync: Native links to Salesforce and HubSpot push activity into your existing CRM system automatically.
This short video breaks down those benefits in order.

Feature Comparison
Ten categories decide this matchup. Each one covers a job your sales team does every week.
| Feature | Instantly | Mailshake |
|---|---|---|
| Starting Price | $30/month | $25/month |
| Free Plan | ❌ | ❌ |
| Free Trial | ✅ 14 days | ❌ |
| Unlimited Email Accounts | ✅ | ❌ |
| Inbox Rotation | ✅ | ❌ |
| Built-in Lead Finder | ✅ | ✅ |
| LinkedIn Automation | ❌ | ✅ |
| Power Phone Dialer | ❌ | ✅ |
| Unified Inbox | ✅ | ❌ |
| Best For | High-volume cold emailing | Multichannel sales outreach |
1. Cold Email Campaigns
Instantly: Volume is the whole design. You connect unlimited email accounts, and the system spreads each campaign across them so no mailbox exceeds a safe daily count. Teams that need to send thousands of cold emails a week get there without buying extra seats.
Mailshake: Campaigns run through the mail accounts you already own. Multi-step sequences stop the moment a prospect replies, and automated follow ups fire on a schedule you set. Daily sending limits depend on your email provider and plan, which caps how far one Mailshake campaign can stretch.
2. Email Deliverability
Instantly: Unlimited email warmups run in the background on every paid tier. Inbox rotation then cycles sends between domains so reputation damage never lands on one mailbox.
A shared deliverability network sits behind the warm-up engine and feeds it real engagement signals.
Mailshake: Deliverability tools include email warm-up, address verification, and throttling that mimics natural sending patterns. Link tracking is built to stay spam-filter friendly. Even so, some reviewers report sudden dips in inbox placement.
⚠️ Warning: Reviewers of both platforms report deliverability drops after scaling too fast. Ramp volume slowly for the first month, whichever tool you pick.
3. Lead Finder and Contact Data
Instantly: The B2B lead finder ships with a database of over 450 million contacts. You can also connect accounts through Google or Outlook, or import a CSV file. Multiple filters narrow the list before you push it into a campaign, and a tracking pixel turns US-based site visitors into fresh growth leads.
Mailshake: The Data Finder pulls verified contact details for prospects you have already targeted. It runs on data finder credits rather than an unlimited pull, so heavy prospecting adds cost. You can filter prospects by title and company before spending them. Mailshake’s Data Finder works best as a top-up, not a primary source to generate leads.
4. Campaign Builder and Templates
Instantly: The builder handles A/B testing, spintax, and a deliverability score before you launch. Email templates save as reusable blocks, and scheduling controls when each step sends.
Mailshake: Mail merge lets you create personalized emails and LinkedIn messages at scale from one spreadsheet. Recipients per campaign are capped by plan, so agencies juggling multiple campaigns hit ceilings sooner than they expect.
5. AI Personalization
Instantly: AI reads company insights for each prospect and drafts an opener that matches. Personalized outreach campaigns then run without a writer touching every row.
Custom AI prompts give you tighter control over tone and angle per list.
Mailshake: SHAKEspeare AI generates copy and subject lines from your campaign goal. An in app copy analyzer flags weak lines before send. It writes well, but it personalizes from your data rather than researching each account itself.
6. Multichannel Outreach
Instantly: Email is the only native channel. Phone calls and LinkedIn outreach need separate tools, which is the main trade-off for its sending power.
Mailshake: One sequence can send an email, wait, fire LinkedIn connection requests, then queue a call task. Personalized campaigns can span phone, email, and social media from one build. The power phone dialer folds cold calling into the same list, and higher tiers include unlimited free dialer minutes. For a sales team working a small target audience, that beats email alone.
7. Lead Management and CRM
Instantly: Instantly CRM is a newer module that handles contact management, deal stages, and custom salesflows triggered by prospect behavior. It centralizes customer interactions so nothing sits in one rep’s inbox. Reps manage leads and deals from one screen. Pipeline depth still trails dedicated crm software, and customizable fields are thin.
Mailshake: There is no native customer relationship management layer. Lead Catcher acts as a triage queue for hot replies, and everything else pushes to Salesforce or HubSpot. That keeps customer relationships in the crm system you already trust.
8. Integrations
Instantly: Native connections cover email providers, webhooks, and Zapier. Direct links to other tools like Google Calendar are lighter, and reviewers describe minimal api integration depth next to older platforms.
Mailshake: Salesforce and HubSpot sync natively, with Zapier covering the rest. Calendar booking links drop straight into email campaigns, which shortens the path from reply to meeting.
9. Analytics and Reporting
Instantly: Campaign analytics track opens, replies, and clicks over time. Sales performance tracking adds pipeline value and closing rates, which helps with forecasting. Export limits apply on lower tiers.
Mailshake: The lead drivers dashboard shows opens, replies, and clicks per campaign. Reviewers call the reporting metrics limited, so teams that need to generate detailed reports often export to a spreadsheet.
10. Pricing & Cost
Here are both lineups side by side.
| Tier | Instantly | Mailshake |
|---|---|---|
| Entry | Growth — $30/month | Starter — $25/month |
| Mid | Hypergrowth — $77.60/month | Email Outreach — $45/month |
| High | Light Speed — $286.30/month | ❌ |
| Custom | Enterprise — Custom | ❌ |
Instantly: Growth costs $5 more than the Mailshake entry plan but adds unlimited mailboxes. Light Speed at $286.30 is aimed at agencies, not a small business. Add ons for lead credits and the CRM module push the real bill higher than the sticker.
Mailshake: Starter is the cheapest way in at $25 per seat. The catch is the per-user model, so a five-person sales team pays five times over. No free plan and no basic plan below Starter exist.
Different Scenarios
| If You Need… | Choose | Why |
|---|---|---|
| Highest sending volume | Instantly | Unlimited mailboxes plus rotation |
| LinkedIn and phone in one flow | Mailshake | Only one with a dialer |
| Prospect data included | Instantly | 450M+ contact database |
| Lowest entry price | Mailshake | $25 vs $30 per month |
| Try before you pay | Instantly | 14-day free trial |
| Salesforce or HubSpot shop | Mailshake | Native two-way sync |
💰 Your Budget
Mailshake wins on the first invoice, then loses as headcount grows. Instantly charges per workspace, so a five-rep team pays once instead of five times.
🔌 Your Tech Stack
Already paying for Salesforce or HubSpot? Mailshake slots in beside them. Running lean with no CRM at all? Instantly covers both jobs in a single place.
📝 Your Outreach Style
Spray-and-refine work across a wide list favors Instantly. Named-account selling with 200 targets and real research favors Mailshake.
🎓 Your Experience Level
Instantly gets praised for a beginner-friendly, user friendly interface. Mailshake carries a steeper learning curve that rewards technical skills and patience.
🆓 Free Trials and Demos
Only one of these lets you look before you pay. Run a 50-contact test on the trial and check reply rate before scaling.
🛟 Support Options
Both support teams draw complaints about slow replies. Slow tickets stall outreach efforts mid-campaign, so budget your own troubleshooting time.

What Our Review Didn’t Cover
This comparison focused on small business and mid-market outbound work. We did not test enterprise contracts, custom API builds, or deliverability across non-English markets. Reviewers report trouble uploading leads correctly on both platforms, and we did not stress-test large imports ourselves. Figures reflect August 2026 pricing, so confirm current terms before you buy.

🏆 WINNER: INSTANTLY
Instantly wins 5 out of 8 categories.
Best for: High-volume cold emailing, agencies managing multiple campaigns, and teams that want prospect data and sending in one tool.
These two products solve different halves of the same problem. Instantly is sales software built around sending capacity and prospect data. Mailshake is a sales engagement platform built around working a shorter list harder.
Sales automation only pays off when it puts real customers in front of reps who are closing deals. Mailshake earns its 4.0 rating on multichannel reach. If your reps close more deals through LinkedIn and phone calls than through email marketing alone, it is the better fit.
For everyone else, Instantly takes it. Unlimited mailboxes, a real lead finder, and a free trial mean you can prove the channel works before you spend much. That combination is why it edges ahead on sales productivity for most businesses.
