Preparation of email/marketing templates in SendGrid (Design Library - drag&drop editor / HTML code).

I am looking for someone to prepare email/marketing templates in the external SendGrid application (Design Library - drag&drop editor / HTML code). https://mc.sendgrid.com/

Technical requirements:

Full drag-and-drop compatibility: Templates must be built using SendGrid markup (role=“modules-container”, role="module" with data-type: image, text, imagetext, columns, button, etc.) so that each component can be edited in the Design Library editor without coding.

Responsiveness and correct display on major email clients: web browsers (Gmail, Outlook.com), mobile apps (Gmail, iOS Mail, Android), desktop programs (Outlook, Apple Mail).

100% compliance with mockups in desktop and mobile versions (within the limits of HTML email).

Table-based structure with inline CSS (priority: Outlook Windows).

Easy content editing by our team at SendGrid after implementation (drag-and-drop modules).

Basic dark mode support (contrasts).

​

Testing and acceptance:

Drag-and-drop testing: Verification that all modules (images, text, buttons, columns) are editable in SendGrid Design Editor after import.

- Rendering testing in email clients.

Delivery: Finished designs in SendGrid + HTML export.
