Proactive Coach
The Proactive Coach gives you live feedback as you write — spam risks, accessibility issues, reading level, and more. It's there to help you catch problems before they reach your audience, not to block you from sending.
Where it appears
On wide screens the Coach panel docks to the right of your message. On narrower screens it collapses into a small badge near the bottom of the page — tap it to open the full panel as an overlay. Either way, it shows the same information.
Summary indicator
At the top of the panel, a colored dot and short label tell you the overall state of your message:
- Green — Looks good — No issues detected.
- Blue — Tips — Suggestions to consider, nothing urgent.
- Amber — Issues — Worth reviewing before you send.
- Red — Critical issues — Something likely to cause problems. Fix these before sending.
Inbox preview
Shows how your subject, preheader, and from-name will appear in a mobile inbox like Gmail. A too-long subject, missing preheader, or generic from-name will be flagged here.
Deliverability
Checks whether your message is likely to land in the inbox or the spam folder:
- Spam-trigger words (free, act now, limited time, etc.)
- Link shorteners (bit.ly, tinyurl) that raise spam scores
- Text-to-image ratio — emails that are mostly images often get flagged
- Malformed link text (the word "click" by itself, or URLs shown as plain text)
- Hyperlinks that don't match what they actually link to
Accessibility
Helps you write messages that work for everyone, including people using screen readers:
- Images missing alt text
- Vague link text like "click here" or "read more"
- Empty links that would confuse a screen reader
- Heading levels skipping (jumping from H1 to H4)
- Text smaller than 14px in body content
- Low color contrast between text and background
Reading
Gives you a feel for how your message reads:
- Word count — Total words in your message
- Reading time — Estimated time to read at an average pace
- Flesch grade level — How complex the language is. Grade 8–10 is comfortable for most audiences.
- Tone — Whether the language reads as casual, neutral, or formal
In-editor markers
The eye icon in the panel header toggles inline markers inside the editor itself. When on, spam-trigger words get a red underline and missing-alt images get a persistent amber outline. Click the eye to turn them off if they're distracting.
Clicking an issue
Each issue in the panel lets you click to jump to the relevant part of your message. For images without alt text, it highlights the image briefly. For spam words, it scrolls to the first occurrence.
Is every flag serious?
No. The Coach is conservative on purpose — it flags things worth looking at, but you know your audience and your context better than any tool can. Use it as a checklist, not a rulebook.
