Our story

Built by outreach obsessives

We spent a decade running cold-email campaigns for clients. Eventually we got sick of duct-taping Lemlist, Clay, and Zapier together, so we built the tool we always wanted.

Mission

Outreach infrastructure that scales with your agency

The tooling around cold email is what's broken. Agencies waste hours every week manually importing leads, writing prompt templates, monitoring reply threads, and generating client reports.

MailTantra puts lead enrichment, AI personalization, multi-account sending, deliverability monitoring, and ROI reporting into one platform built around how agencies actually work.

Who it's for

Built for agencies running cold email at scale

MailTantra isn't a general sales automation suite trying to cover every channel. It's built specifically for teams whose core workflow is cold email: agencies running outreach for multiple clients, and in-house teams booking their own meetings through cold email rather than inbound.

That focus is deliberate. Deliverability, inbox warm-up, and multi-mailbox sending behave differently at agency scale than they do for a single founder sending a few hundred emails a month, so we built around that reality instead of bolting cold email onto a broader sales automation product.

A good fit if you're
  • An agency running cold email campaigns for more than one client at a time
  • Managing multiple sending mailboxes and need warm-up and deliverability handled in one place
  • Tired of stitching together a separate warm-up tool, a separate enrichment tool, and a separate sequencer
  • Looking for pricing that doesn’t punish you for adding teammates or clients

How we think about the product

Speed over perfection

A good email sent today beats a perfect email never sent. We build tools that ship campaigns in minutes, not days.

Deliverability first

We are obsessed with inbox placement. Every feature we ship is tested against real providers before it reaches your campaigns.

Agencies, not individuals

Multi-client workspaces, role-based access, and white-label reporting, all built for teams managing more than one client.

Radical transparency

We tell you when something breaks, explain what happened, and keep you posted while we fix it.
