AI does the heavy lifting, people stay in charge

Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the stated task modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. One approved brand kit and licensed asset set; final brand, legal and deliverability checks remain with the marketing team. A model suggestion is never a verified fact, professional decision or authorization to act.

What your team sees

Primary screens: Campaign brief and references, Editable email preview, Client proof and delivery. Use a thumbnail gallery for campaigns, a large central editing canvas, and a right-hand panel for brand kit, constraints and comments. Let users compare versions side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant email block. Make the task-specific outcome reviewed, tested, send-ready emails visible beside its evidence, review state and value baseline.

Accounts and administration

Project ownership, asset versions, client comments, approval states, usage allowances, revision limits, download history and a rights record for supplied material. Add organization access boundaries, named reviewers, usage caps, data retention controls, export logs and explicit approval for external actions.

Integrations and data access

Buyer-owned brand assets, ESP accounts and permitted web sources. Cloud asset storage, design-file import/export and ESP destinations. Start with file exchange and validate destination specifications before promising direct sending. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.

    Monthly

    We host, monitor and improve it for a fixed monthly fee, or hand it over to your team. How the retainer works.

Why we start with an MVP

An MVP, or minimum viable product, is the smallest version that your users can actually work with. It is not a cheap version of the full solution. It is a test, built to answer the questions that decide whether the rest is worth building.

  1. Pick the riskiest assumption. Here: will marketing teams and agencies producing recurring on-brand email campaigns use it to solve "email design, copy, brand styling, testing and sending are split across several rented tools, so campaigns are slow and off-brand"?
  2. Build only what tests it. One team, one use case, a few core modules. People do the rest by hand for now.
  3. Run a paid pilot. Agree quality and outcome thresholds before the pilot using this measure: Approved emails per production hour and corrections after send.
  4. Measure, then decide. Track approved emails per production hour and corrections after send; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase. Then expand, change course or stop, with evidence instead of opinions.

MVP scope for this solution. Pilot scope: One approved brand kit and licensed asset set; final brand, legal and deliverability checks remain with the marketing team. Implement one approved input format, a bounded representative case set and the first two task modules: generate complete emails or templates from simple text prompts; apply brand colors, fonts and styles automatically. Support the remaining modules with operator review: produce responsive emails; push or integrate with ESPs. Include source references, corrections, basic organization access, approval states, export and value measurement. Use managed operator assistance for unresolved exceptions. The cost estimate covers this narrow prototype, not unrestricted multi-tenant scale, complex production integrations, specialist certification or physical operations.

After the MVP. Once paid pilots prove usefulness, automate repeatable reviewed steps and add one verified ESP integration. Expand supported inputs and case volume only after new evaluation cases pass. Build reusable customer configurations and recurring value reports around reviewed, tested, send-ready emails. Retain the explicit scope boundary: One approved brand kit and licensed asset set; final brand, legal and deliverability checks remain with the marketing team.

What the build depends on. Asset upload and preview, asynchronous generation jobs, editable version history, reviewer access and tested export formats. High-fidelity production requires specialist creative QA. Obtain representative authorized cases, baseline measurements, qualified reviewers and a buyer-side decision owner. Specific limitation: One approved brand kit and licensed asset set; final brand, legal and deliverability checks remain with the marketing team.

Run it or resell it

Internally

For your own team

Marketing teams and agencies producing recurring on-brand email campaigns run it inside the business: brand kits, prompts, links, Figma files, audience lists and ESP credentials in, reviewed, tested, send-ready emails linked to the buyer's ESP out, reviewed by your people.

For your clients

As part of your offer

Agencies, consultancies and software companies can offer it to their own clients under their brand. We build and maintain it; you sell and deliver it.

Your brand, or this one

Pricing to test

Test a USD 300-1,500 fixed pilot for one defined campaign package. Offer a monthly production allowance after repeat demand. Quote complex localization, video or specialist design separately. These are test prices, not market benchmarks. Package the initial sale as one bounded reviewed, tested, send-ready email. Recurring fees must specify volume, review depth and integration support. For exchanges, test a disclosed coordination or successful-service fee rather than holding customer funds. Reprice only after measuring real delivery labor; platform-build cost is separate from a commercial pilot fee.

Message to test

Reduce campaign production time while keeping every email on-brand. Demonstrate a concrete reviewed, tested, send-ready email using the buyer's approved example and show the baseline, corrections and actual delivery effort.

Where to find buyers

Marketing teams and agencies producing recurring on-brand email campaigns professional communities; specialist consultants serving this buyer; permissioned partner introductions; practical demonstrations at relevant trade or practitioner events.

Lead magnet

A reviewed sample reviewed, tested, send-ready email from a small authorized input set, with a transparent calculation of approved emails per production hour and corrections after send and no promised savings.

The first 30 days

  1. Week 1: interview five marketing teams and agencies producing recurring on-brand email campaigns and inspect a recent example of email design, copy, brand styling, testing and sending split across several rented tools.
  2. Week 2: prepare a consented or synthetic demonstration of the task modules.
  3. Week 3: seek one bounded paid pilot with agreed baseline and acceptance criteria.
  4. Week 4: measure approved emails per production hour and corrections after send, reviewer effort and repeat-purchase interest. This is a demand-validation plan, not a thirty-day full-product delivery promise.

Paid pilot

Agree quality and outcome thresholds before the pilot using this measure: Approved emails per production hour and corrections after send. Continue only if the buyer accepts the actual output, the intended job outcome improves without unacceptable errors, and measured delivery cost fits willingness to pay. Revise or stop if access is unavailable, qualified review cannot be provided, or apparent savings disappear after corrections and support. Use held-out cases when comparing model quality; use a properly reviewed comparison design before making causal claims. Record missing cases and negative results alongside successful outputs.

Success metrics

Approved emails per production hour and corrections after send; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase.

Retention and expansion

Repeat the workflow when the buyer again needs reviewed, tested, send-ready emails. Retain permissioned settings and reviewed examples, report realized value honestly, and sell increased volume or adjacent approved workflows only after contribution margin and quality remain acceptable.

Why clients would pick it

A reusable library of approved brand kits, component layouts and review examples, together with reliable delivery for a narrow marketing niche. Build a permissioned library of representative campaign cases, reviewer corrections and verified operating constraints for marketing teams and agencies producing recurring on-brand email campaigns. Repeatable delivery and useful integrations matter more than access to a base model.

Alternatives and positioning

Migma AI, Bluor AI, AI Email Template Generator, MagicMail: AI email generator and Newsletter Pilot, plus freelancers, agencies and generic design tools. Compare this product with the buyer's present method on approved emails per production hour and corrections after send. Offer a bounded paid workflow instead of claiming broad autonomous expertise. Market uniqueness and competitor coverage are not verified.

Main delivery costs

Generation attempts, image processing, storage, reviewer hours, client revision rounds and licensed source assets. Additional initial validation requires representative authorized sample preparation, buyer interviews, buyer-side evaluation and bounded validation of reviewed, tested, send-ready emails. Track cost per accepted output, including correction work, unsuccessful cases and support.

06

Safeguards

Preserve brand voice, source attribution, quotation accuracy and usage permissions. Marketing owners approve substantive changes and send scope. One approved brand kit and licensed asset set; final brand, legal and deliverability checks remain with the marketing team. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
