Variable selection hard to discover

[sefsh]

Description

A user should be able discover the variable selection of the email composer with more ease.

Estimated size (S, M, L)

I think this issue is M because it may include some overhead of designing and building a more generalized approach to "first-run UX".

Prerequisites

Requirements

• define what a "user not having composed an email before" is
• decide when not showing modal
• design the modal

Possible implementations

When entering the composer, display a modal with image/animation and text explaining the composer core principles (including how to add variables) for users not having composed an email before.
