Why HTML email signatures break, and how we fix it

Email apps are not web browsers. Outlook on Windows uses Microsoft Word to display email, Gmail strips many styles, and some apps block images by default. A signature that looks fine in a web page can arrive broken. SignTry is built around those limits:

  • Email-safe layout. Every template is made to hold up in Gmail, Outlook, Apple Mail and Yahoo Mail.
  • Hosted images. Photos and logos are optimized and hosted when you save, so they load instead of arriving as attachments.
  • Mobile check. Switch the live preview to phone view before you save.

How to add your HTML email signature

Click Copy on your signature, then paste it into your email app's signature settings. Here is where to find them:

Email appWhere to paste your signatureGuide
GmailSettings → See all settings → General → SignatureGmail guide
Outlook (new and web)Settings → Account → SignaturesOutlook guide
Outlook (classic, Windows)File → Options → Mail → SignaturesClassic Outlook
Apple Mail (Mac)Mail → Settings → SignaturesApple Mail guide
iPhone and iPadSettings → Apps → Mail → SignatureiPhone guide
Yahoo MailSettings → More Settings → Writing email → SignatureYahoo guide

Paste with Ctrl+V (or Cmd+V on Mac), not “paste as plain text”, or the formatting and images will be lost.

Need the raw HTML code?

Each signature in your library has a code button that gives you the HTML. Use it to deploy signatures through your own tools or to paste into apps that only accept HTML, such as Apple Mail on a Mac or some CRM and help desk tools.

Frequently asked questions

What is an HTML email signature?

An HTML email signature is a signature built with HTML code, so it can include formatting, a photo, a logo, colored text and clickable links and icons, instead of plain text only.

How do I add an HTML signature to Gmail?

Copy your signature in SignTry, then in Gmail open Settings, See all settings, General, Signature, create a new signature and paste it. Our Gmail signature guide has screenshots.

How do I add an HTML signature to Apple Mail?

On a Mac, open Mail, Settings, Signatures, add a new signature and paste. On iPhone, go to Settings, Apps, Mail, Signature and paste. See our iPhone and Apple Mail guide.
