Marketing

Email Platform for Marketing Teams

Visual campaign builder, AI composer, and real analytics. No code required. No developer bottleneck.

The Challenges

Why Marketing email is hard

Developer Dependency

Need a developer to change a template, update a list, or debug a bounce. Marketing shouldn't need a PR to send a campaign.

Bloated Feature Tax

Enterprise platforms bundle CRM, SMS, landing pages, and chatbots you don't use. You pay for everything, use the email part.

Opaque Deliverability

Campaigns go out. Open rates drop. You have no visibility into why, and support says 'check your content.'

The Solution

How Transmit helps Marketing Teams

Visual Campaign Builder

WYSIWYG editor with HTML fallback. Build, preview, and schedule campaigns without writing code or filing tickets.

AI Composer (Coming Soon)

Describe what you want in plain text, get production HTML. Brand kits ensure every email matches your style guide. Multi-provider AI (Google, OpenAI, Anthropic).

Deliverability You Can See

Real-time opens, clicks, bounces, and complaints. Automated warmup prevents reputation damage. DNS health checks run continuously.

Developer Experience

No-Code? Use the Dashboard. Have an API? Even Better.

Our API is built for the modern edge. No heavyweight SDKs, just simple REST and standard protocols.

Frequently Asked Questions

Do I need a developer to use Transmit?

No. The dashboard has a visual campaign builder, list management, and template editor. Developers can use the API, but it's not required. AI Composer is coming soon.

How will the AI Composer work?

Coming soon. Describe your email in plain text and choose a provider (Google, OpenAI, or Anthropic). Set up a brand kit once with your colors, tone, and logo. Every generated email matches your brand.
