Whistle for Klaviyo

Send with confidence with automated Klaviyo account monitoring.

Whistle keeps an eye on your Klaviyo accounts and tells you when something breaks. It's built for agencies and marketers running busy accounts who don't have time to check everything by hand.

Whistle's in the works.

We're building Whistle now. Leave your email and we'll let you know when it's ready.

Whistle's pre-send checks flag placeholder text, a wrong link domain, and missing audience exclusions in a scheduled Klaviyo campaign.

For busy teams that need to operate with confidence.
