# Why your email looks different in some inboxes

> Why heading fonts, dark mode colors, spacing and images can look a little different in Gmail, Outlook and Apple Mail, and what AveryIQ does about each.

Every mail app draws email its own way. AveryIQ builds each email blast to
hold up in all of them, but a few differences are normal.

## Heading fonts

Apple Mail on iPhone, iPad and Mac shows your heading font. Gmail, Outlook
and most others don't load custom fonts, so they show a close standard font
instead. Your words, colors and layout stay the same. Body text always uses
a standard font, so it looks the same everywhere.

## Dark mode

When someone reads in dark mode, AveryIQ swaps your colors for dark versions
of the same branding. Some apps, Gmail especially, also change colors on
their own. AveryIQ's colors are never pure white or black, which keeps those
changes gentle, and your logo gets a version made for dark backgrounds.

## Spacing in Outlook

Outlook on Windows can add or trim a little space around pieces. Buttons are
built so they still show and work there.

## Long emails get cut off

Gmail cuts off emails over about 100 KB with a "View entire message" link,
which would hide your footer and its unsubscribe link. AveryIQ keeps
emails well under that, and if one gets too big (lots of pieces or very
long text), the checklist asks you to shorten it before it can be sent.

## Images turned off

Some people's mail apps don't load images until they ask. They see each
photo's description instead, which is why every photo needs one. Keep the
important words, like the price and the date, in text rather than inside a
picture.

## Phones

On a phone, side-by-side pieces stack one under the other. Check **Mobile**
in **Preview** to see it.
