Mailto hyperlinks


Using Hyperlinks (in Twixl .publications or .articles in InDesign), you can launch the reader's mail client and create a new mail message. This article explains how to use the mailto: syntax (so you can prefill some fields for your reader) and tackles some difficulties for Android devices.


For more info about other Hyperlinks, see this article: Hyperlinks

1. General Example

1.1. What?

Let's say you want to achieve the following result: A clickable hyperlink that will prepare a new email for your reader with some prefilled text.

Field Value
To: to@email.com
CC: cc@email.com
BCC: bcc@email.com
Subject: This is the Subject.
Body: This is the Body.

1.2. Syntax

The syntax for this example is as follows:  



Syntax Description
This is the startpoint, it opens the reader's mail-client with a new empty mail and the To: Field prefilled with the address to@email.com
This syntax tells that you want to add an option to this url. In this case you want the CC: Field prefilled with the address cc@email.com . Extra options after the first option needs to be added with & as a prefix. The first option after mailto always needs the prefix ? . The following options can also be added:
Option to prefill the BCC: Field
Option to prefill the Subject: Field. Don’t forget to replace each space by %20.
Option to prefill the Body: Field. Don’t forget to replace each space by %20.

2. Example with a url in the prefilled Body.

Adding a url to the Body can be tricky. If you do this with the standard syntax, it will not work on Android devices.

2.1. What?

mailto url in the body
Field Value
To: to@email.com
Subject: A Body with a url.
Body: https://www.twixlmedia.com

2.2. Syntax

The correct syntax for this example is as follows:


So, the tricky part is the url. You can't use a standard url like https://www.twixlmedia.com . You will need to encode that url first. You can encode a url by using one of these free online tools:

The result for https://www.twixlmedia.com will be https%3A%2F%2Fwww.twixlmedia.com . It's this encoded url that you need to embed in the syntax of your mailto: url.


Always test before you publish! More info about Preview on device can be found here.
