Action

Create A/B test variation

Creates a new a/b test variation for an existing hubspot email, using its `contentid`; this action only creates the variation, it does not start the a/b test or send emails.

Why this helps

A/B testing emails requires manually creating variations in Hubspot, which disrupts marketing workflows. Your team discusses ideas in Slack but creating the test variation feels like bureaucracy.

  • Create email test variations without leaving Slack
  • Speed up testing cycles and iteration
  • Keep marketing team focused on strategy, not setup
  • Empower faster experimentation and learning

Setup

Build it in a few focused steps.

  • 1Connect Slack and Hubspot to Notis.
  • 2Create an automation: 'When someone reacts with a test emoji to an email idea in #marketing, create an A/B test variation in Hubspot.'
  • 3Choose your test emoji (e.g., test tube, fork, or custom).
  • 4Your marketing team discusses email ideas and reacts to flag which ones to test.
  • 5Notis creates the variation in Hubspot, ready for your team to customize and launch.

Questions about this workflow

Does Notis create different subject lines or just the body?

You specify what should vary in the test (subject line, body text, images, CTA). Notis creates the variation framework.

Do I need to link the variation to the original email?

Notis handles the linkage automatically, setting up the A/B test relationship in Hubspot.

Can I run multiple A/B tests on the same email?

Yes. React multiple times with different variations to create multiple test branches.
