Horizon makes it easy to create beautiful, mobile-friendly emails. This could include newsletters, auto-response or triggered emails and internal messages to staff.
How to create an email message
1. Click the | Content | tab
2.Click | Add new message content |
3. Give your message a name. Try to use a consistent naming scheme for your messages to make it easy to find them again.
4. Select a message template as the starting point for your message or follow steps 5 to 11 below. You can create message templates to make creating a message easier. To do this, go to 'Re-usable templates' under 'Message content'. Set up is the same process as below.
5. Tick the opt-in categories that are relevant to this message. Horizon will then ensure that it is only sent to contacts if they have subscribed to receive messages from one of the selected categories. For more information, see Setting up your Opt-in Categories.
6. Tick "Email".
7. Select the email address that this message will be sent from. If you're a new Horizon customer this will probably be an address ending in "htkhorizon.com", however Horizon can be setup to send emails from your own domain name - Please contact us for further details.
8. Enter the "sender name" that subscribers should see. This should be something that subscribers will recognise. You shouldn't change the sender name too often, as this leads to confusion with subscribers, resulting in lost customers and spam complaints. Always warn customers of any changes.
9. Select the email address that any email replies will go to (if a subscriber receives your email and clicks "reply"). Contact us if you'd like any additional reply address to be added.
10. Think about an engaging subject line that will encourage your contacts to open the email.
You can personalise the subject line using things like the first name of each contact. To do this, click the person icon. You can also apply a variable subject line, allowing customers of different groups see a different subject line. To do this, click the edit/pencil icon.
11. Select an email layout as the starting point for your email design. If this email is to be sent as part of a campaign, make sure you use an email layout that contains an "unsubscribe" link or be sure to add an "unsubscribe" subscriber action link yourself. For more information see Setting up your Subscriber Preference Centre.
12. If you selected an email layout that supports Themes, select a theme from the dropdown list (themes are a quick way to select things like the default colours and fonts).
If you'd like a custom theme that matches your website branding, let us know. We can either create one for you or advise your design agency or internal team on how to do this.
If you're using the new content editor, you'll see the custom blocks as below. If not, skip the old editor section.
Adding custom blocks
When creating an email in Horizon, you can add building blocks by dragging them onto your email from the list of “custom blocks” on the left.
You can also move rows within the email once they have been added, by clicking the left-hand 
“drag” icon and dragging the selected row to a new position:

Allows you to clone the custom block.
Allows you to delete the custom block. It will ask you to select Yes to confirm this, so as to avoid accidental deletion.
If you'd like other kinds other custom blocks to be available, let us know - the ones in our standard email layouts are there for starters, but it's very easy for someone with HTML skills to add new ones. We can either create them for you or advise your design agency or internal team on how to do this.
