Email infrastructure, simplified.

Connect your email providers, manage your subscriber lists, send campaigns, build automations, monitor reputation and control everything from one place.

Mailstampede gives you one consistent platform across Amazon SES, SendGrid, Mailgun and any server via custom SMTP.

You keep control of your providers. Mailstampede makes them easier to manage.

The problem

Email infrastructure gets complicated fast.

Sending an email is easy. Operating professional email infrastructure is not. Businesses need to manage provider accounts, API credentials, sending limits, bounces, complaints, webhooks, reputation, analytics, retries and provider failures.

Every provider has its own API, its own dashboard, its own configuration and its own way of handling events. Mailstampede brings these moving parts together into one consistent platform.

The platform

One platform. Multiple email providers.

Connect multiple supported email providers and manage them from one place. Use different providers for different purposes, add backup providers, or change providers without rebuilding your entire email infrastructure.

You log in, build your lists, campaigns and automations, and Mailstampede manages the provider layer underneath. You are not tied to one provider or one delivery network.

MAILSTAMPEDE built to scale · engines, events and workspaces multiply as you grow Lists & segments Templates Campaigns Automations Sending engine routing · failover · warmup quotas · rate limits · tracking Amazon SES SendGrid Mailgun Custom SMTP Live events deliveries · opens · clicks · bounces outgoing email live feedback
Everything scales: engines, live events and workspaces.

You should never have to care which provider sends an email. You build the campaign and Mailstampede picks the right provider based on your routing rules, respects each provider's limits, and falls back when one can't be used. The provider layer is configuration you can change at any time, not something your campaigns are built around.

Campaign safety

Every campaign passes a safety check before it goes out.

Mailstampede validates the complete sending path, sender, domain authentication, provider, reputation, volume and audience, before a single email leaves the platform. Problems surface as clear statuses instead of failed campaigns.

Pre-flight check March newsletter
Sender identity Verified
Domain authentication DKIM · SPF · DMARC Passed
Provider health credentials · quota Healthy
Reputation signals domain · IP · provider Good standing
Sending volume Within safe range
Audience suppressed & invalid removed Clean
All checks passed Send campaign

Every campaign gets a clear verdict before sending: Ready Warning Blocked and anything critical stays blocked until it is fixed.

Fewer failed campaigns. Fewer configuration mistakes. Better sender reputation. Safer email delivery.

Template editor

Design your emails right inside Mailstampede.

A built-in template editor lets you design campaign emails without any external tools. Start from one of the professionally designed templates or build your own from scratch.

Every template you create is reusable across campaigns and automations, so your brand stays consistent in every send.

  • Visual editor built into the platform
  • Ready-made designed templates to start from
  • Reusable across campaigns and automations
Automations

Customer journeys that run themselves.

Build automated flows with triggers, delays, conditions, splits and email actions. Set the rules once and Mailstampede handles every subscriber from there.

  • Trigger on signups and subscriber events
  • Wait steps, conditions and branching splits
  • React to behavior like opens and clicks
  • Safeguards pause flows cleanly when a sender or provider changes

Why Mailstampede

Built around the infrastructure behind email.

Most tools bolt providers on. Mailstampede is built around them: your accounts stay yours, providers become configuration you can change at any time, and switching never means rebuilding your campaigns, automations or lists.

Traditional email infrastructure

  • Separate provider accounts to juggle
  • Events and stats scattered everywhere
  • Separate dashboards
  • Provider-specific quirks and limits
  • Separate monitoring
  • Manual provider switching
  • Campaigns tied to one provider
  • Single-provider dependency

Mailstampede

  • One sending layer
  • Multiple providers
  • Unified provider management
  • Unified event handling
  • Centralized analytics
  • Routing and failover
  • One login for everything
  • Flexible provider infrastructure
Who it's for

One platform, three ways to use it.

Built for businesses

Manage subscriber lists, campaigns, templates, automations, providers, analytics and reputation without building all of the supporting infrastructure yourself.

Built for agencies

Manage multiple customers through separate workspaces while keeping their providers, campaigns, automations and data isolated.

Built for high-volume senders

Spread big sends across several providers, stay inside every quota and rate limit, and keep delivering even when one provider has a bad day.

Your providers. Your infrastructure. One platform.

Mailstampede gives you one layer between your business and your email providers, making email easier to configure, manage and scale. Change your infrastructure without rebuilding your email stack.
