How it works

Personalized calendars in 3 steps

Built inside the Personalized Image editor you already know.

1

Add a calendar layer

Open the Personalized Image editor and add a calendar component. Configure the month, layout, and styling.

2

Set highlighted dates

Mark specific dates with colors, icons, or markers. Use merge tags or Data Sources to personalize per subscriber.

3

Paste & send

Drop the image URL into your email. Each subscriber sees a calendar with their own dates highlighted at open.

Use cases

Calendars that drive action

Event highlights

Webinars, conferences, product launches, or sales periods — show subscribers exactly when it happens on a visual calendar.

Renewal & billing dates

Show each subscriber their upcoming renewal, billing cycle, or trial end date highlighted on a personalized calendar.

Seasonal promotions

Holiday campaigns, multi-day sales, or content calendars — visualize the entire promotion window at a glance.

B2B milestones

Internal communications with project milestones, contract dates, or quarterly deadlines visualized for each recipient.

Course schedules

Show class dates, assignment deadlines, or exam schedules personalized per student or cohort.

Sale countdowns

Highlight sale start and end dates on a calendar alongside countdown timers and personalized offers in a single image.

Ecosystem

Calendars inside personalized images

Calendars are built as layers in the Personalized Image editor — not a separate tool. Combine a calendar with a subscriber's name, a countdown timer, a chart, and a coupon code all in a single image. One URL, one creative, fully personalized.

Localization

Calendars in any language

Select a language or culture setting to automatically localize weekday and month labels. Serve calendars to global audiences without maintaining separate templates per region.
