TL;DR

  • Risky means the email couldn't be definitively confirmed, but it's not automatically invalid.

  • The most common cause of a Risky label is a catch-all domain.

  • Risky addresses can be exported and used — just with slightly more caution than Good addresses.

  • Consider isolating Risky addresses into their own campaign if deliverability is highly sensitive.

When you'd use this / Why it matters

Seeing "Risky" in your verification results can feel like a red flag, but it doesn't mean the same thing as "Bad." This article helps you decide confidently whether to export and use Risky addresses in your outreach.

What does Risky actually mean?

Risky is ListKit's label for emails that couldn't be verified with full certainty — usually because the domain is a catch-all (see "What is a catch-all email address and should I send to it?" for the full explanation). It does not mean the email is confirmed invalid.

ListKit runs deeper checks than most standard verification tools, which is why these are labeled Risky rather than simply excluded or marked Bad. In most cases, the email likely exists and can receive mail — the domain configuration is just what makes certainty harder.

Should I export Risky addresses?

In most cases, yes. Risky addresses can be included in your export and used in campaigns. The key is understanding the tradeoff:

Reasons to include them:

  • Maximizes your total addressable list size

  • Many Risky/catch-all addresses perform normally in outreach

  • Excluding them entirely can meaningfully shrink your available leads

Reasons to be cautious:

  • If you're highly sensitive to bounce rate or domain reputation, isolating them reduces risk

  • New or unwarmed sending domains may benefit from starting with only Good addresses first

Best practice approach

  1. Export your list including Good and Risky addresses

  2. Run Good addresses in your primary campaign

  3. Test Risky addresses in a separate, smaller campaign

  4. Monitor bounce and reply performance before scaling Risky sends further

Expected outcome

You should now be able to:

  • Explain what a Risky label means and why it's assigned

  • Decide whether to export and use Risky addresses

  • Apply a segmented testing approach to manage any added uncertainty

Troubleshooting / FAQs

Is Risky the same as unverifiable?
Close, but not identical. It means ListKit couldn't confirm the address with full certainty — most commonly due to catch-all domain behavior — not that it's invalid.

Will including Risky addresses increase my bounce rate?
It may increase it slightly, but typically stays within normal, healthy benchmarks. See "Why do my bounce rates matter and what should I aim for?" for expected ranges.

Should new domains avoid Risky addresses?
It's a reasonable precaution while warming up a new domain — start with Good addresses, then introduce Risky ones once your sending reputation is established.
