Run a Marketing agency headless

A marketing agency runs on the same operational work every day. Mailable gives you a team of agents to run it: Content, SEO, campaigns and reporting, shipped on a schedule. You set direction and approve the calls that matter.

Your marketing agency agent team

Lifecycle marketers

Run sequences and funnels without a dedicated email specialist.

Content & brand

Ship newsletters that look designed, every single week.

Demand gen

Pair campaigns with matching high-converting landing pages.

What runs itself

  • Newsletters and weekly sends that look designed
  • Launch campaigns with matching landing pages
  • Nurture and drip sequences from a single brief
  • Webinar and event invitations
  • AI-generated A/B variants of copy, layout, and CTA
  • Repurpose winners into your brand kit

The old way

  • Every campaign competes for the designer’s time
  • The email and its landing page never quite match
  • A/B testing rarely gets past a subject line

Headless, a marketing agency hands all of this to a team of agents, and your people move to the work only they can do.
