What is Mailshake?
Mailshake is a B2B sales engagement platform trusted by over 100,000 companies to automate and scale cold outreach across email, LinkedIn, and phone. Built with a focus on deliverability and simplicity, Mailshake enables sales teams to build multi-channel campaigns in minutes, track engagement with pipeline-focused analytics, and surface the hottest prospects through its Lead Catcher dashboard.
Whether you’re a solo founder running your first cold email campaign or a sales team coordinating outreach across dozens of mailboxes, Mailshake provides the automation, AI assistance, and deliverability tools needed to book more meetings without sacrificing personalization.
Key Features
AI-Powered Email Writing with SHAKEspeare
Mailshake’s proprietary SHAKEspeare AI writer helps teams generate personalized cold email copy in seconds. Instead of staring at a blank screen, sales reps can input their value proposition and let the AI craft subject lines, opening hooks, and calls to action. Combined with Spintax randomization, every email looks handwritten rather than mass-produced.
Multi-Channel Outreach
Mailshake consolidates email, LinkedIn, and phone outreach into a single platform. Sales teams can build sequences that automatically send LinkedIn connection requests, follow up with InMail messages, trigger cold calls through the power dialer, and send email follow-ups—all from one campaign workflow. This multi-touch approach dramatically increases reply rates compared to email-only outreach.
Deliverability Optimization
Mailshake takes inbox placement seriously with a suite of deliverability tools included in every plan:
- Free Email Warmup: Gradually increases sending volume to build sender reputation
- List Cleaning: Removes invalid, catch-all, and risky email addresses before sending
- Domain Setup Assistant: Guides users through SPF, DKIM, and DMARC configuration
- Custom Tracking Domains: Prevents shared domain blacklisting
- Spam Word Analysis: Flags phrases that trigger spam filters
These features help customers achieve open rates of 83% or higher—far above industry averages.
Lead Catcher Dashboard
Not all prospects are created equal. Mailshake’s Lead Catcher automatically surfaces engaged contacts who opened your email multiple times, clicked your link, or replied. Sales reps can prioritize follow-up with hot leads rather than wasting time on cold contacts who never engaged.
Advanced Split Testing
Unlike most cold email platforms, Mailshake offers robust A/B testing for subject lines, email body copy, and entire campaign sequences. Teams can test variables like send time, personalization tactics, and messaging angles to continuously optimize campaign performance.
Data Finder for Prospecting
Mailshake’s Data Finder tool filters prospects by role, location, and company, then enriches contact records with verified email addresses. The Sales Engagement plan includes 2,500 free credits per month, eliminating the need for separate lead generation tools.
CRM and Tool Integrations
Mailshake integrates natively with Salesforce, HubSpot, Pipedrive, and dozens of other CRMs. Zapier connectivity extends compatibility to 1,000+ tools. The unified inbox consolidates replies from multiple mailboxes, and email rotation distributes sends across addresses to prevent hitting daily limits.
