Campaign Probe

Campaign Probe is built for the moment when a campaign leaves staging and starts behaving like a real send. It gives teams a controlled way to capture campaign output, inspect what arrived, and review quality before problems spread across a full audience.

When to use Campaign Probe​

Use it when you need to:

  • review live campaign output from your ESP or application
  • verify that the correct subject lines, senders, and variants are going out
  • capture samples from an active send for QA or marketing sign-off
  • keep ongoing visibility into campaign quality after launch

What makes it different from deliverability tests​

  • Deliverability tests answer "did the selected cohort receive what we expected?"
  • Campaign Probe answers "what is actually being delivered right now, and does it look correct?"

Teams often use both together during major launches.

Typical operating model​

  1. Set up the capture addresses or monitoring path for the campaign.
  2. Start the send from your ESP or application.
  3. Review the captured output for sender, subject, content, and variant quality.
  4. Escalate issues before widening the audience or approving the next campaign stage.

Best paired workflows​

Good use cases​

  • canary launches
  • release-day campaign QA
  • lifecycle journey reviews
  • high-risk transactional message changes
