Email Theme Customizer

Every platform sends email: verification, password resets, notifications, account updates. Email Theme Customizer makes those look like they came from you rather than from generic defaults.

Find it at Settings > Email Theme once the add-on is active.

This is design, not delivery

Who the email comes from is set in Email Setup. This add-on controls what it looks like once it arrives. Configure the sender first, otherwise you are branding emails that still come from a fallback address.

Publishing

You edit a draft, preview it against real templates, and publish one approved design. Until you publish, your platform keeps sending the SpaceMedia defaults, so there is no in-between state that reaches customers half-finished.

If the license is not active yet, you can still edit and preview. Publishing unlocks once it is.

Getting it right

Email rendering is far less forgiving than the web. A few things that consistently matter:

  • Use a hosted logo URL that is publicly reachable. Anything behind a login shows as a broken image.
  • Keep the logo modest. Many clients scale images unpredictably, and a huge header pushes your actual message below the fold.
  • Check contrast on the button. Button text over your brand color is the single most common readability failure.
  • Assume images are blocked. A meaningful proportion of recipients see text only, so the email must still make sense without the logo.
  • Preview on a phone. Most platform email is opened on mobile.

Send yourself a real password reset before you publish. The preview is accurate, but a real message in a real inbox catches things the preview cannot.

If you deactivate it

Editing stops and the sidebar entry disappears. If nothing has been published, the SpaceMedia default design stays in place, which means emails always send correctly regardless of what happens to the theme.

Common questions

Can I edit the wording of the emails? No. This controls the visual design. The content of platform emails is standard.

Does this affect emails I send from my own systems? No, only emails the platform sends.

Will this improve deliverability? No. Deliverability comes from domain authentication in Email Setup.

Can I publish more than one design? One published design applies to your whole platform.
