How grading works
A second opinion before you hit send.
Before you send that email, let us grade it. We’ll review your email across 12 categories and give you feedback on what’s working well and what needs a second look.

12 categories
Score your email across 12 categories.
Each email you grade is scored across 12 categories inboxes and subscribers care about most.
Subject line
Length, clarity, and whether it survives a phone screen.
Preview text
Whether the preview adds to the subject or just repeats it.
Sender
From name and address, the first thing anyone reads.
Copy
Length, scannability, and whether it talks about the reader.
CTA
One clear ask, named specifically, placed where it gets seen.
Personalization
Relevance past a first name, and merge tags that won't break.
Layout
Structure, mobile-readiness, file weight, and Gmail's clipping limit.
Images
Alt text, image-to-text balance, and what shows with images off.
Accessibility
Contrast, text size, dark mode, and how a screen reader hears it.
Deliverability
Links, hidden text, and the content signals that shape where it lands.
Trust & compliance
Unsubscribe, mailing address, and the things that keep you out of spam.
Purpose fit
Whether the email does the job this kind of send exists to do.
Sending it in
Three ways to send it in.

Paste the HTML from your email platform, or drop in an .html or .eml file.

Send a test
Every account gets a grading address. Send a test there from your platform and it arrives exactly as subscribers get it, so your sending setup is graded too.
Forward it
Forward one of your own sends from your inbox to the same address. We work out the email type for you, and you can change it and re-grade.
Your grading address is on My Emails once you sign in, with Google or a link we email you. Everything you grade stays private to your account.
What you get
What comes back.
Your grade
A score out of 100, a letter grade, and one line on what's working and what isn't.
Suggested fixes, ranked
Each suggestion shows how many points it adds to your score, so you know where to start.
Suggested rewrites
For your subject line, preview text and button, only when we think they beat yours.
Where it's likely to land
Primary, Promotions or Updates, and how much spam risk it carries. A prediction, not a promise.
Your sending setup
SPF, DKIM and DMARC checked against your domain when you send a test or upload an .eml, with what to change and where.
Your account
Everything you grade and save, in one place.
Sign in and My Emails keeps every email you’ve graded with its report, every email you’ve saved from the gallery, and your grading address. See something you like while you browse? Save it. It’s the swipe file you’ll actually come back to.
Making the gallery
Make the grade, make the gallery.
Every email in the gallery earned a B− or better on this same review. When yours makes the grade, nominate it right from your report. A person reads every nomination, and if it’s approved your email goes live with its grade, the categories it’s strongest in and a note on why it works, where email marketers come looking for their next idea.
