Changelog

WhatsApp campaign A/B testing is now generally available

After a 6-week beta with 80 merchants, A/B testing is rolling out to all WhatsApp campaigns. Run up to 4 variants, set a confidence threshold, and Helio will auto-promote the winner.

We saw an average lift of 23% in reply-to-purchase rate from beta merchants who used multivariate tests.

• Up to 4 variants per campaign (was 2)
• Confidence threshold configurable from 80–99%
• Auto-promote winner option
• Per-variant revenue attribution in the dashboard

Faster product sync for stores with 10k+ SKUs

We rewrote the Shopify product sync pipeline. Initial sync is 4× faster on stores with large catalogs, and incremental syncs run every 90 seconds (down from 5 minutes).

Fixed: brand voice settings reverting after import

If you imported a brand voice template, your custom tone settings could be overwritten on the next agent retrain. This is fixed — your custom settings now always take precedence.

Instagram story replies in beta

Helio can now respond to Instagram story mentions and replies, not just DMs. Customers who react to your story get a personalized follow-up that links back to the product they're interested in.

• Auto-reply to story mentions
• Pull product context from the story
• Opt-in beta — toggle in Channels → Instagram

Klaviyo deep integration

Two-way sync between Helio and Klaviyo. Conversations and conversions now flow into Klaviyo segments, and Klaviyo audiences are available as triggers in Helio campaigns.

Dashboard performance and accessibility pass

The campaigns dashboard now loads 60% faster. Also: full keyboard navigation, improved screen reader labels, and a new high-contrast theme toggle.
