What Is Mailshake and What Is It Used For?

Mailshake is a sales engagement and cold outreach automation platform. It is used to run personalized outreach campaigns across email, phone, and social channels from a single sequence and dashboard. It fits teams that want to start sending campaigns quickly—Mailshake states a new rep can be sending on their first day—and that want to use their own email provider rather than switch inboxes.

Core capabilities

Mailshake's feature set is built around getting a message in front of a prospect and then following up automatically:

• Email cadences and automation — build multi-step outreach sequences that send and follow up on a schedule.
• Mail merge — send one customized email to an entire group rather than writing each message individually.
• Automated follow-ups — increase response rates without manually tracking who has replied.
• Multi-channel outreach — combine email, phone (via an integrated dialer), and social messages in one sequence.
• Social automation — send messages automatically on social networks for multi-channel social selling.
• Lead Catcher — surfaces your most engaged leads so reps can focus on prospects most likely to convert.
• Pipeline-focused analytics — track opens, replies, and clicks at the team level.
• AI Email Writer — auto-generate email copy in under a minute.
• Data Finder — find prospect emails.
• Deliverability tooling — purpose-built features aimed at landing in the inbox rather than spam.
• Integrations and CRM sync — use your own email provider and populate your CRM with the leads you engage.

Who it is for

Mailshake positions the product around three audiences:

The common thread is volume outreach that still needs to feel personal—teams sending many sequences but wanting replies and meetings rather than just sends.

What outcomes does it claim?

Mailshake frames its value as a chain: more emails landing in prospect inboxes, plus more replies, plus more meetings booked, equals more revenue per rep. The site cites customer results including an 83% open rate at Virtuance using personalized emails, a 10x increase in email volume at BrandStar, and over $800K generated by New Reach Marketing through personalization at scale. These are vendor-published customer claims, not independent benchmarks—treat them as illustrations of intended use rather than guarantees.

When Mailshake is a good fit

• You already have an email provider you want to keep and need outreach automation layered on top.
• You want email, calling, and social touches managed in one sequence instead of separate tools.
• You need reps productive quickly, with shared team templates to speed setup.
• You are an agency or sales team running high-volume campaigns and need engagement analytics to manage performance.

When to look elsewhere

• You need a full CRM as the system of record—Mailshake is built to populate your CRM, not replace it.
• Your outreach is low-volume and highly bespoke, where automation adds little.
• You need pricing details before deciding: Mailshake publishes a pricing page, but plan costs, limits, and any login requirements should be checked there directly rather than assumed.

Getting started

1. Connect your own email provider so outreach sends from your existing address.
2. Build a campaign using shared team templates or the AI Email Writer, then personalize with mail merge fields.
3. Add follow-up steps and, if relevant, dialer and social steps to the same sequence.
4. Launch and monitor opens, replies, and clicks; use Lead Catcher to prioritize engaged prospects.
5. Sync engaged leads into your CRM.

The main things to verify before committing are your plan's sending limits and how your email provider's sending rules interact with campaign volume—both affect deliverability, which is the outcome the whole workflow depends on.
