Mailshake

Mailshake is a sales engagement and cold outreach platform built around a connected email account. It automates email campaigns and adds a browser-based VoIP dialer, plus scheduled manual tasks for phone, social, and general outreach.

Because email is sent through the connected account, buyers retain responsibility for the account and its sender setup rather than using Mailshake as the sending infrastructure.

Email is the automated core: campaigns support configurable delays, automated follow-ups, drip messages, click-triggered messages, reply-based stopping, A/B tests, and prospect imports from CSV, manual entry, or lists. Sales engagement sequences can also schedule calls, LinkedIn activities, social media tasks, and general tasks.

The multichannel model has a clear boundary. Mailshake can queue LinkedIn messages, connection requests, follows, unfollows, and profile views, but the user completes those actions in LinkedIn. Calling is supported through its browser-based dialer.

Text Replacements support mail-merge personalization, and users can edit messages for individual prospects before launch. SHAKEspeare adds AI-generated email variants, rewrites, follow-ups, A/B test variations, and Spintax-based text randomization.

For sender protection, Mailshake includes warm-up, verification or list cleaning, sending address rotation, scheduling, daily limits, throttling, and automatic quota pauses. Rotation supports up to 50 sending addresses. These controls help operationalize sending, but provider quotas, SPF/DKIM or DMARC authentication, reputation, list quality, and campaign practices remain important determinants of inbox placement.

Mailshake natively connects with HubSpot, Salesforce, Pipedrive, Slack, SMTP, Vidyard, and Microsoft Email, and its directory also includes services like Google Calendar, Calendly, Twilio, and Nimble. Zapier expands the integration options, while the public API supports API keys or OAuth 2, campaign and recipient endpoints, activity data, rate limits, and webhooks.

Reporting covers sends, opens, clicks, replies, unsubscribes, bounces, campaign comparisons, lead status and drivers, completed tasks, and call outcomes. CRM workflows can import records, create or update contacts and deals, and move records through pipeline stages, though custom fields are not synced when Mailshake creates a person record.

Mailshake fits sales teams, outbound marketers, growing teams, and agencies that want structured email outreach with calling, task-managed social touches, CRM synchronization, and reporting. The Starter plan is designed for businesses just beginning an outreach program, while the Sales Engagement plan is built for advanced multichannel programs.

It is less suitable for buyers that require fully automated social network messaging. Teams should also be prepared to manage their connected email accounts, authentication, reputation, and recipient list quality.
