Instant Release Notes | Q2 2026
SMS Prefix now supports up to 12 characters (for Australia)
Released 1st May
What's new?
- All SMS from Instant AI require a brand prefix
- This aligns with Australian requirements every SMS must have the business name
- You can select a short prefix or long prefix
- If selecting a short prefix, you'll be allowed up to 4 characters and can personalise the url link and your prefix name
- If selecting long prefix, you'll be allowed up to 10 characters, but no customisations of the url link

Improved breakdown of filters in past Campaigns
Released 1st May
What's new?
- Campaigns with long and complex filters are now easier to navigate with an easier UI

Upload Custom Fonts
Released 28th April 2026
What's new?
- You can now upload your own custom font file to use across your Instant AI emails
- Go to Settings > Email Settings > Custom Font, select Upload Font, and upload a WOFF2 file
- Add multiple weights (Regular, Bold, etc.) for the same font family
- Once uploaded, your custom font applies to all text in your emails — both headings and paragraphs
- Your Default Font is still required and acts as the fallback for email clients that don't support custom fonts
Add a Google Font
Released 20 April 2026
What's new?
- You can now pick one Google Font and apply it across every email Instant AI generates
- It applies to everything, including all text across Flows and campaigns Campaigns
- Set it under Settings > Email Settings > Style > Custom Font (Optional)
- Your existing Default Font remains as the fallback, so recipients in clients that don't support web fonts still see a clean, on-brand email

CSV Export
Released 14 April 2026
What's new?
- You can now export your Shoppers list as a CSV directly from the Shoppers page
- Go to Shoppers > Select Menu in the right corner > Export as CSV
- You can also export Flow Activity from any flow's Activity tab
- Go to Flows > Select Flow > Activity > Download button in right corner
- Both exports reflect whatever filters you have applied, so you can filter first and download exactly what you need
Custom Attribution Windows
Released 13th April 2026
What's new?
You can now customise the attribution window Instant uses to measure email and SMS revenue, directly from your settings.
- By default, Instant uses a 5-day open/click window for email and a 1-day click window for SMS, matching Klaviyo's standard settings
- Switch to Custom to set your own open and click windows independently for email and SMS
- Set either value to 0 to remove that interaction type entirely, for example, 0 open days and 1 click day gives you a 1-day click-only model
- Email and SMS are configured separately, reflecting how the two channels are measured differently across the industry
- Changes apply retroactively and immediately, your full dashboard and flow analytics update the moment you save, so you can compare what any period looks like under a different model
- Find it in Settings > Email Settings > Preferences > Attribution window

More ways to conditionally show email content with Rules
Released 10th April 2026
What's new?
- Instant AI now lets you manually create dynamic content within your emails
- Instead of one email for everyone, you can now tailor the design based on who's receiving it. Certain customers can get one image, others might get another.
- Use cases like, Show a sale banner only during your sale, then it auto-disappears, a different hero for repeat buyers, or exclusive content for subscription customers
- Rules are filters you apply to blocks inside your email, so we know which block we should use for which customer, without altering any flows
- There are two ways to use Rules: insert a new block that only appears when a condition is met, or replace an existing block with a different version for specific customers
- You can chain multiple conditions together — if the first isn't met, Instant tries the next, and so on
- Filter by location, purchase history, email activity, Shopify tag, or a scheduled date range
- Date-based Rules activate and expire automatically — set it once and your emails update themselves
- Replacing an existing block updates it everywhere it appears across all your emails at once
