AI email design

A designed HTML email from the brief. In the client’s brand. In seconds.

The client’s brand preset holds the identity. The campaign preset holds the offer, the audience, the message, the proof and the tone. From those, the platform designs a complete HTML email — hero, sections, offer band, proof, footer — in several creative variants, ready to send. Your clients will assume you hired a designer and a copywriter. You filled in a brief.

Why this changes the economics

The bottleneck in agency email was never the sending. It was the making.

An agency running twelve clients’ email produces forty or fifty campaigns a month. Each needs a subject line that earns the open, a design that earns the click and a version or two to test. That work lands on a designer and a copywriter who have other jobs, gets done late, and drifts from client to client because nobody has time to re-read the brand guidelines.

Generic AI tools do not fix this, because they do not know the client. They produce a competent, forgettable block of text in the same voice for everyone — and then someone has to design it anyway.

SendTo’s AI knows the client because the brand preset tells it: the logo, the colours, the tone, the words the client uses and the ones they never would. The campaign preset tells it the offer, the audience, the key message, the call to action and the proof. From that structured brief it produces a designed email a client can approve on sight — and it produces the creative variants in the same pass, so the test is ready when the design is.

Designs, plural. Every client, its own look — and its own layout.

A dental practice gets a clean clinical hero layout in teal and white. A boutique gets an editorial, text-first layout in black and pink. A property agency gets a split layout with the listing beside the headline. A restaurant gets a magazine grid. The platform designs the layout as well as the styling, to the brand preset — so no two clients’ emails look alike, and no two campaigns for the same client are cut from the same template.

  • Layouts designed per campaign, never one template
  • Colours, fonts and voice from the brand preset
  • Photography chosen to suit the brief

Presets do the remembering

A brand preset holds the client’s identity: logo, colours, tone, vocabulary. A campaign preset holds the offer kit: headline, call to action, proof points, audience. Set them up once when you create the client and every future campaign starts from them. Update the preset and every future draft follows. The fortieth campaign sounds like the first.

  • One brand preset per client, reused forever
  • Campaign presets for recurring offers
  • Feeds the email and the landing page together

Then the editor is yours

The draft lands in the editor. Regenerate a section, tighten a headline, swap the hero photo from the media library, rewrite the close by hand. The AI is a colleague with a strong first draft, never a black box with a button — and every edit stays inside the brand.

  • Regenerate any section on its own
  • Media library with stock photography built in
  • Edit anything, keep the design

For your business

The margin on every campaign just changed.

A day of production becomes an afternoon

Your account managers draft with the AI and hand the creative team a design to finish, instead of a blank page to start. Same team, twice the clients.

Design work you can sell on subscription

Clients who would never pay for a designer per campaign will pay every month for a platform that designs every campaign. That is the retainer.

Charge for the outcome, keep the time

Bill the client for campaigns that look like this. Spend the time you saved on the next client.

½ dayper campaign, from a full day

The drafts are good enough that our copywriter now edits instead of writes. That is not a small change in an agency.

Priya RamanCreative Director, Fieldnote Digital
FAQ

Questions

How good are the designs, honestly?

Good enough that partners edit rather than rebuild. Because the platform works from the client’s brand preset and a structured campaign preset rather than a prompt, the result is specific to the client — layout included. The gallery on this page is the kind of output it produces.

Does it write in my client’s voice?

Yes, from the brand preset: tone, vocabulary, words to avoid. The more the preset says, the more specific the draft.

Can I use my own designs?

Yes. Build in the editor, import your own HTML, or start from the AI and change everything. The AI is there when you want it.

Does the AI see my client’s subscriber data?

No. It works from the brand preset, the campaign preset and your brief. It never reads a list.

Does it produce the landing page too?

Yes — that is the next step in the campaign builder, generated from the same brief so the page and the email agree with each other.

Fill in the brief. Ship the campaign.
