HippoMango Email Check
Sample report A worked example on a fictional brand, so you can see the output before finding an email of your own. Produced by scanning an uploaded .eml file; pasting HTML runs fewer checks. A real scan looks identical without this banner.

We inspect HTML without rendering it, so we cannot fully determine which elements are visible across devices and email clients.

The offer check is running one of its three rules. The other two have never been confirmed against real email, so they are held back rather than shown to you unproven.

What to fix

High priorityNo mailing address

No physical mailing address found in footer

US commercial email is required to carry a complete postal address: a street or PO box with a city, state and postal code. We searched the HTML text and the image descriptions.

How to fixAdd your postal address to the footer. Every major sending platform has one setting for this that applies to all of your emails at once.
End of the emailWelcome to Tidewater Goods. We make coastal homewares in small runs, and we are glad you are here. Your discount applies automatically at checkout, no code needed. Start with our linen throws , woven on the same looms we have used since 2014, then work your way through the rest of the house. Thanks for reading — the Tidewater Goods team.

High priorityTwo offers that contradict

Image description gives code "SETTLEIN" but the email also says "no code needed"

The email states both that a code is required and that none is. Whichever a reader acts on, the checkout may not behave the way the email said it would.

How to fixDecide which is true. If the discount applies automatically, take the code out of the image. If it needs a code, remove the wording that says none is needed.

Medium priorityA link the copy promised but never got

The copy intended a link on "linen throws" and it was never given a destination

Nothing here looks clickable, so no reader hits a dead end. The phrase was written to send people to a page and the link was never finished, so those clicks are not being offered at all.

How to fixAdd the destination, or remove the link formatting so the phrase reads as ordinary text.
Link textlinen throws
Medium priorityNo plain-text version

Email has no plain-text version

A plain-text version provides an alternative for readers who cannot use the HTML version. Some spam filters also treat formatting-only email as a negative signal.

How to fixTurn on the plain-text version in your sending platform. Most will generate it from your HTML once the setting is on.
Medium priorityAn unsubscribe nobody can see

Unsubscribe link has no visible text

The link is in the email but renders as nothing, so a reader looking for a way out cannot find it. A hard-to-find unsubscribe option may lead to spam complaints.

How to fixGive the link visible text. The word “Unsubscribe” is enough, and screen readers need it too.
Link addresshttps://tidewatergoods.example/unsubscribe/8c21f
Low priorityLeftover template text

3 images use placeholder image description "Image"

This is the description the template shipped with. It is read aloud by screen readers and shown whenever images fail to load.

How to fixReplace it with a short description of what each image shows.
