# Responsive HTML mail signatures
|
|
### Let's punch email clients in the stomach!
|
|
Responsive templates for mail signatures. <br/>
|
|
|
|
When you need some basic signatures that work on mobile.<br/>
|
|
...and your colleagues need them too.<br/>
|
|
...but you don't want to deal with tables and inline styles.
|
|
|
|
## Preview
|
|
Here's how the samples look:
|
|
|
|
|
|
|
|
|
|
## Motivation
|
|
Let's make writing HTML emails & email signatures easier. We won't fix all email clients, but we can surely make the process of satisfying them a tad nicer. <br/>
|
|
See a fairly comprehensive rant on the subject (and not only) [in this article](http://fadeit.dk/blog/post/html-emails-and-email-signatures-how-hard-can-it-be).
|
|
|
|
|
|
## What does it do
|
|
- [x] config-based template generation
|
|
- [x] allows generating multiple templates (for your colleagues too!)
|
|
- [x] transforms linked (`<link>`) CSS into inline styles
|
|
- [x] embeds local `img[src]` into the template (base64).*
|
|
- [x] minifies the template
|
|
- [x] media queries for mail clients that support them
|
|
- [x] can build templates from multiple sources
|
|
- [x] watches HTML/CSS files for changes and re-builds
|
|
|
|
|
|
**Some mail clients don't support them, so an external URL might be a good idea.*
|
|
|
|
|
|
## Getting started
|
|
```
|
|
$ npm install
|
|
$ gulp
|
|
```
|
|
|
|
Take a look at `src/fadeit/` for an example. Copy / Paste, rename it and change `src/fadeit/conf.js` to suite your needs. Run `gulp` to build the templates (into `/dist`). The gulp task will watch HTML & CSS files by default.
|
|
|
|
## Overview
|
|
This diagram shows what happens to your templates.
|
|
|
|
|
|
|
|
## CSS Support
|
|
Remember, it's HTML mails, so you need to check a big-ass table to find out nothing's gonna work.
|
|
See [this](https://www.campaignmonitor.com/css/). To convert CSS files to inline styles [gulp-inline-css](https://www.npmjs.com/package/gulp-inline-css) is being used.
|
|
|
|
|
|
## TODO
|
|
- [x] closing `inline-css` issue [#8](https://github.com/jonkemp/inline-css/issues/8#issuecomment-149025428) would greatly improve this repo
|
|
- [ ] preprocessor support (simplifies BEM)
|
|
- [ ] use github pages to show live demos
|
|
- [ ] check [gulp-inline-css](https://github.com/jonkemp/inline-css) for new features
|
|

## Usage with different e-mail clients
|
|
|
|
### Thunderbird
|
|
There are several Thunderbird plugins which can automatically insert signatures when composing e-mails. We recommend [SmartTemplate4](https://addons.mozilla.org/en-us/thunderbird/addon/smarttemplate4) as one of the options. It can use different templates for new e-mails, replies and forwarded e-mails.
|
|
|
|
|
|
### Apple Mail / OS X (oh boy)
|
|
|
|
#### Solution 1
|
|
- Open Mail.app and go to `Mail` -> `Preferences` -> `Signatures`
|
|
- Create a new signature and write some placeholder text (doesn't matter what it is, but you have to identify it later).
|
|
- Close Mail.app.
|
|
- Open terminal, then open the signature files using TextEdit (might be different for iCloud drive check the article below).
|
|
```
|
|
$ open -a TextEdit ~/Library/Mobile\ Documents/com~apple~mail/Data/V3/MailData/Signatures/ubiquitous_*.mailsignature
|
|
```
|
|
- Keep the file with the placeholder open, close the other ones.
|
|
- Replace the `<body>...</body>` and it's contents with the template of your choice. *Don't remove the meta information at the top!*
|
|
- Open Mail.app and compose a new mail. Select the signature from the list to test it out.
|
|
|
|
**NB**: Images won't appear in the signature preview, but will work fine when you compose a message.
|
|
|
|
|
|
####Solution 2
|
|
You can also open the HTML files in `/dist` in a browser, CMD + A, CMD + C and then paste into the signature box. This won't copy the `<html>` part or the `<style>` part that includes media queries. Follow the guide if you want it.
|
|
|
|
|
|
#### Troubleshooting
|
|
|
|
If solution #1 doesn't work, you can repeat the steps and lock the signature files before you open Mail.app again.
|
|
Lock Files:
|
|
```
|
|
$ chflags uchg ~/Library/Mail/V3/MailData/Signatures/*.mailsignature
|
|
```
|
|
|
|
If you want to do changes later, you have to unlock the files:
|
|
```
|
|
$ chflags nouchg ~/Library/Mail/V3/MailData/Signatures/*.mailsignature
|
|
```
|
|
|
|
