Customize Email Notifications In Sublium Subscription
Step 1: Click on the email notification to set up its details
Select the email notification you want to customize by clicking on its name. This will open the settings and allow you to begin editing.

Configure the following fields:

- Reply-To Email: The address where recipients can respond.

Step 2: Set personalized subject line and preview text
Next, it’s time to set the subject line and preview text.
To personalize the email and subject line, you can use a Merge tag to add dynamic information.
To add any merge tag, hit the “{ } Merge Tag” button, then search for the merge tag you like, copy it, and then paste it to add it to your subject line and preview text.

For this notification, configure these two options:
- Subject: Set the subject line of the email.
- Preview Text: Set the text displayed in the inbox before opening the email.

Step 3: Choose email template type
Sublium offers two template types for email customization:
- Rich Text: Basic text editing with limited customization options
- Visual Builder (Recommended): Allows for advanced customization with drag-and-drop content block features. Provides full control over the design and layout of your subscription emails
Choose the one you prefer to start customizing the email body content.

Step 4: Customize email with Rich Text (method 1)
You get a prebuilt text-based template with Rich text template type.
Choose Rich Text and start editing.
Here are the customization options you get
- Font selection – Choose different fonts (e.g., Book Antiqua).
- Font size adjustment – Change text size (e.g., 14px).
- Text style/format – Apply paragraph styles, headings, etc.
- Bold text – Make text bold.
- Italic text – Make text italic.
- Numbered list – Create ordered/numbered lists.
- Bullet list – Create unordered/bulleted lists.
- Blockquote – Format text as a blockquote.

- Clear formatting – Remove existing formatting from text.
- Insert image – Add images to the content.
- Insert media/audio – Add audio or media files.
- Insert table/keyboard input – Add tables or specialized content like keyboard input.

Again, like the Subject line and Preview text, here you can use merge tags to personalize the message. Plus, to direct users to different dynamic links, like the My Account page, you can add merge tags in the links.
