Design your email
Once your domain and sender are ready, you can start creating your email. Just click Add email to get started:

When setting up your email, you’ll need to fill out the following:
Field | Description |
---|---|
Email name | A name for internal reference |
Associated app | Link the email to an app (optional but helps with organization and reporting) |
Sender | The email address you’ll use to send the email |
Recipients | Choose who gets the email based on different conditions: • App events: installs, uninstalls, etc. • Customer info: email, tags, lifetime value (LTV), and more • Subscription details: status, plan, amount, and other subscription data • Segments: use pre-defined segments from your customer view (In the image, we’re using a segment called “Trials”) |
Sending schedule | Decide whether to send manually, set it up to send automatically based on triggers (like an app install, uninstall, review, or subscription change), or trigger it as part of a flow. |
Unsubscribe group | Select the appropriate unsubscribe group for this email |
After setting up the email details, click Continue to start designing your email’s look and feel.

Mantle gives you the ability to create and edit your emails the way you’d like to.
- Use Mantle’s easy to use drag and drop editor to add sections and create your email from scratch.
- Add your own emails by dropping in your own HTML and CSS.
- Create email templates called Layouts that will save
Layouts
Create reusable layouts for your emails (totally optional!) - Just design a base layout with your branding, go-to links, and other stuff you use all the time.
Save it as a layout, and you’re set - for each new campaign, you can start with your saved layout and just add the unique bits.
It’s a great way to keep your emails looking consistent without starting from scratch every time, but you can always create emails from scratch if you prefer.
To create a layout:
- Navigate to Email in the main menu
- Select Layouts from the dropdown
- Click Add layout
The highlighted area in your layout shows where your dynamic content will appear. When you create an email using a layout, any content you create - whether using the rich text editor, email editor, or custom HTML - will automatically populate in this section.
This makes it easy to maintain consistent branding while customizing the main content for each campaign.

Ready to use your layout? Just pick it when creating your email, and your content will automatically pop into the dynamic content section:

Adding and customizing content
Mantle’s email builder gives you powerful tools for creating stunning marketing emails quickly. Whether you start with a beautiful template or build from scratch, you can combine various content blocks and personalize your message with custom images, text, and branding.

Click on the email preview to open the email editor, where you can customize your message and make it uniquely yours:

Adding blocks
Mantle’s email editor offers a diverse range of content blocks to help you create engaging and visually appealing emails. From simple text and image blocks to more complex layouts with logos, CTAs, and social icons, you have all the tools you need to craft professional-looking emails that match your brand.

To edit the block you’ve added, click Edit on the block itself:

Once blocks are added, simply click into the block to edit visual settings and add content:

You can modify any part of your content and incorporate liquid variables to create dynamic, personalized emails:

Conditional blocks
Want to make a block show up only sometimes? Here’s how:
- Add the block you want to your email
- Click Edit on the block
- Click the Show block conditionally button:

- Pick the conditions that decide when the block shows up

For example, you could create a block containing a specific discount code that only appears for a targeted segment of customers.
Moving, hiding & inspecting elements
Our editor features a built-in inspector mode, allowing you to click on any element to view and edit its properties:

At any point, you can change the view of your email to see how it would look on desktop, tablet and mobile devices:
