Deliverability

Catch the spam-folder mistakes before you send.

Run a spam analysis on a composed broadcast right in the editor. It scans the same things filters scan — subject patterns, content structure, trigger-word density, compliance markers — and returns a score with specific fixes, while you can still make them.

How it helps

Before, not after.

Catch it before you send

Run the analysis on the composed broadcast and find the content and structure problems that hurt placement while you can still fix them — not in a bounce report after the send has already gone out.

Scans what filters scan

Subject-line patterns, content structure and text-to-image balance, spam-trigger word density, and the presence of required compliance markers — the same signals receiving filters weigh when they decide inbox or spam.

A score with reasons

You get a number and, more usefully, the specific recommendations behind it — so you know exactly what to change. Fix the flagged items, re-run, and ship with confidence.

Where it lives

One button, in the editor.

The analyzer sits in the broadcast editor's preview-and-test panel. Compose as usual, hit Analyze Spam Score, read the notes, adjust, and re-run — a tight loop that turns "I hope this lands" into "I checked, and it should."

It's a content check, not a substitute for the fundamentals — authentication, clean lists, and good sending reputation still do the heavy lifting. But it catches the avoidable content mistakes that send an otherwise-fine campaign to the promotions tab or the spam folder.

What it prevents

The own-goals you find out about too late.

  • Spam-trigger words you didn't notice

    A subject stuffed with "free" and "act now" reads as spam to filters. The analyzer flags trigger-word density so you can soften the copy before sending.

  • Image-heavy emails with no text

    An all-image email trips content filters. The structure check warns on a poor text-to-image ratio while you can still add copy.

  • Missing compliance markers

    A send without a physical address or unsubscribe link is both non-compliant and spam-flagged. The analyzer confirms they're present.

  • Finding out from the bounce report

    A content problem discovered after the send is a wasted campaign. The pre-send score surfaces it while it's still fixable.

What the score catches

The content own-goals, caught pre-send.

  • A shouty subject

    In the draft
    ALL-CAPS or "FREE!!! ACT NOW" in the subject line.
    What the analyzer does
    Flags the pattern and trigger-word density so you soften it before filters read it the way you didn't intend.

  • An all-image email

    In the draft
    A beautiful design with almost no real text.
    What the analyzer does
    Warns on the text-to-image ratio that trips content filters — add copy while you still can.

  • Missing compliance bits

    In the draft
    No physical address or unsubscribe link in the footer.
    What the analyzer does
    Confirms the required markers are present, so the send is both compliant and not auto-flagged as spam.

  • A high-stakes launch

    In the draft
    A campaign you can't afford to land in spam.
    What the analyzer does
    Run the score, fix the flagged items, re-run to confirm it dropped, and schedule knowing the content side is clean.
“It's saved me from myself more than once. I'd written a launch subject in caps with three exclamation marks because it felt punchy — the analyzer flagged it, I toned it down, and the score dropped into the green. It doesn't replace good authentication, but it catches the dumb content mistakes before they cost a campaign.”

Common questions

What buyers usually ask.

What does the analyzer check?

Subject-line patterns (ALL-CAPS, excess punctuation), content structure and text-to-image balance, spam-trigger word density, and required compliance markers like a physical address and unsubscribe link — the content signals filters weigh.

Where do I run it?

In the broadcast editor's preview-and-test panel. Compose the email, hit Analyze Spam Score, review the recommendations, adjust, and re-run — all before you schedule.

Does a good score guarantee inbox placement?

No — it's a content check, not a guarantee. Authentication, list hygiene, and sender reputation are the bigger factors. The analyzer catches the avoidable content mistakes that can sink an otherwise-healthy send.

What do I do with the result?

Each flagged item comes with a specific recommendation — soften this subject, add text here, drop these trigger words. Fix the items that matter, re-run to confirm the score improved, then send.
