We thank the contributing authors for creating these themes.
If you want to supply your own custom theme or add a new built-in theme, check out THEME.md for instructions.
To change the default text direction (left-to-right), simply override it as follows:
var mailGenerator =theme: 'salted'// Custom text directiontextDirection: 'rtl';
To customize the e-mail greeting (Hi) or signature (Yours truly), supply custom strings within the e-mail
var email =body:greeting: 'Dear'signature: 'Sincerely';
To use a custom title string rather than a greeting/name introduction, provide it instead of
var email =body:// Title will override `name`title: 'Welcome to Mailgen!';
To customize the
copyright, override it when initializing
Mailgen within your
product as follows:
// Configure mailgenvar mailGenerator =theme: 'salted'product:name: 'Mailgen'link: ''// Custom copyright noticecopyright: 'Copyright © 2016 Mailgen. All rights reserved.';
To inject multiple lines of text for the
outro, simply supply an array of strings:
var email =body:intro: 'Welcome to Mailgen!' 'We\'re very excited to have you on board.'outro: 'Need help, or have questions?' 'Just reply to this email, we\'d love to help.';
Mailgen supports injecting custom elements such as dictionaries, tables and action buttons into e-mails.
To inject an action button in to the e-mail, supply the
action object as follows:
var email =body:action:instructions: 'To get started with Mailgen, please click here:'button:color: '#48cfad' // Optional action button colortext: 'Confirm your account'link: '';
To inject multiple action buttons in to the e-mail, supply the
action object as follows:
var email =body:action:instructions: 'To get started with Mailgen, please click here:'button:color: '#22BC66'text: 'Confirm your account'link: ''instructions: 'To read our frequently asked questions, please click here:'button:text: 'Read our FAQ'link: '';
To inject a table into the e-mail, supply the
table object as follows:
Note: Tables are currently not supported in plaintext versions of e-mails.
To inject key-value pairs of data into the e-mail, supply the
dictionary object as follows:
var email =body:dictionary:date: 'June 11th, 2016'address: '123 Park Avenue, Miami, Florida';
You can make use of Gmail's Go-To Actions within your e-mails by suppling the
goToAction object as follows:
var email =body:// Optionally configure a Go-To Action buttongoToAction:text: 'Go to Dashboard'link: ''description: 'Check the status of your order in your dashboard';
Note that you need to get your sender address whitelisted before your Go-To Actions will show up in Gmail.
- After sending multiple e-mails to the same Gmail / Inbox address, they become grouped and truncated since they contain similar text, breaking the responsive e-mail layout.
Simply sending the
X-Entity-Ref-IDheader with your e-mails will prevent grouping / truncation.
