SMALL DETAILS. REAL FRICTION.

Catch the mistakes between
a click and a customer.

A clear finding, the evidence behind it, and a practical next step.

A promotion with nowhere to click

The “Shop the Fall Collection” image has no link attached.
THE FIX
Give the promotional image a destination.

One offer. Two different instructions.

The image description says “use code SETTLEIN.” The email also says “no code needed.”
THE FIX
Make the discount instructions consistent.

A product link left unfinished

The email mentions “linen throws,” but the intended link has no destination.
THE FIX
Connect the product mention to the right page.

Example findings. Available checks depend on your input and permissions.

HOW EMAIL CHECK WORKS

From email file to a list of fixes.

A useful review shouldn’t bury the answer or pretend to test what it can’t.

01 · Bring your email

Paste HTML or upload an email message. The checks available depend on what you provide.

02 · Review the findings

See what ran, what couldn’t run, and any supported issues the scan uncovered.

03 · Make the fix

Get a concise explanation and the next action, without vague scores or inflated claims.

CLEAR ABOUT COVERAGE

What your scan
can and can’t check.

Paste HTML

Review supported content checks using the HTML you provide. Paste cannot supply email MIME structure.

Upload an .eml file

Include the message structure needed for additional checks, such as whether a plain-text part is present.

Read the coverage summary

Each report identifies what ran and what couldn’t. A scan does not verify rendering across email clients.

Live link visits, product availability and platform-connected flow checks require access beyond the basic paste/upload scan.

Before you run a check.

Can I share the report?

Download an HTML report to share with a colleague. The print-friendly layout also supports saving to PDF through your browser.

Does a clean scan mean my email is error-free?

No. It means no issues were found by the checks performed. Coverage tells you what those checks included.

Do I need to connect Klaviyo?

No account, credentials or OAuth connection is needed for the paste/upload checker.

What happens to my email?

Email content is discarded after processing. Reports are not published as public pages.
