Email content, banners, CTAs

This guide covers the shared email fields used across OmniLab notifications: Email Subject Line, Email Preheader, Email Banner, Email Content, Email CTA Label, and Email CTA Link.

The shared email block

Every notification type uses the same email structure. What changes from one type to another is the trigger and the selected scope, not the fields themselves.

That makes these content rules reusable whether you are editing Winner, Touchpoint Unlocked, or a booking notification.

Email Subject Line

Use Email Subject Line to tell the recipient what happened before they open the email.

Good subject lines are:

• specific about the outcome
• short enough to stay readable on mobile inboxes
• clear even without the preheader

{{ contact_firstname }}, your booking for {{ event_title }} is confirmed
You won {{ reward_display_name }}
Your reward from {{ enterprise_name }} is ready

Email Preheader

Email Preheader is the short text many inboxes show next to the subject line. It is not mandatory for delivery, but it is strongly recommended because it improves context and often improves open rates.

Use it to add the next most useful detail, such as a date, location, or action:

• the booked slot
• the reward redemption step
• the reason to open now

Email Banner

Email Banner gives the message visual context at the top of the email.

Current banner guidance for notification emails:

• Recommended size: 900 x 600 px
• Ratio: 3:2
• Supported formats: JPEG, WEBP, PNG

Use the specs link in the upload control when you need example dimensions. Keep the focal point centered and avoid putting essential tiny text inside the banner image.

Email Content

Email Content is the main body of the message. Lead with the outcome, then immediately tell the recipient what to do next.

Best practices:

• Put the main outcome in the first two lines.
• Keep paragraphs short for mobile reading.
• Use clear headings or short sections when the message is longer.
• Do not hide critical information only inside the banner image.

All text fields support Liquid variables, so you can personalise the message with contact, reward, booking, or Touchpoint data. See Liquid templates and variable bindings.

CTA label and link

Use a CTA only when the email needs a clear next action, such as opening a landing page, viewing booking details, or starting redemption.

Rules:

• Email CTA Label and Email CTA Link must be used together.
• Email CTA Link must start with http:// or https://.
• Use action-based labels such as View my booking, Redeem my reward, or Open campaign.

If the email is purely informative, leave both CTA fields empty.

Mobile, dark mode, and readability

Most notification emails are read on phones, so optimise for quick scanning:

• keep the most important information above the fold
• avoid long image-heavy layouts
• make sure links and CTAs are understandable out of context
• test the message in your email platform before launch, especially if you use strong brand colours or image-led banners
