Suppression, and removing a prospect
The do-not-contact list is the one control that stops Kai reaching someone, whatever the source, whoever imported them. It lives under Settings > Sending. This article covers what it blocks, what fills it automatically, and how to get a single person out of a campaign that is already running.
What suppression does
Suppression is checked at intake. A suppressed email or domain never becomes a contact in the first place, so it cannot be researched, cannot be written to, and cannot be pushed to your outreach platform. It does not matter whether the address arrived from a CSV, a HubSpot list, an always-on campaign, or a rep adding someone by hand. The check happens before any of that.
This is why it is the right tool for the categories you never want to contact: competitors, existing customers handled by another team, partners, and anyone who has previously asked not to hear from you.
Adding entries
Open Settings > Sending. Paste emails or domains into the box, one per line, add an optional reason, and click Add to list.
- An email blocks that one address.
- A domain blocks every address at that domain.
competitor.comstops all of them at once.
Domains are normalised as they are saved, so a scheme, a path, or a leading www. all reduce to the bare host. Pasting https://www.competitor.com/careers stores competitor.com and works as you would expect.
The reason field is optional and worth filling in. Six months later, "existing customer, owned by AM team" is the difference between trusting a rule and deleting it because nobody remembers why it is there.
What fills the list on its own
Kai adds entries automatically when a reply is classified as not interested or as an unsubscribe. That happens without anyone doing anything, and it is the main reason the list grows over time. Those entries show their source in the table, so you can tell an automatic addition from one somebody typed.
Reviewing and removing entries
The Current entries table below the box shows the most recent 500 rules with their type, reason, and source. Each row has a Remove button.
Getting one person out of a live campaign
Suppression blocks contacts at intake, so it does not by itself pull someone who is already in a running campaign. Which control you want depends on where they are.
They are waiting in the approval queue
Open the three-dot menu on their row. Remove from queue parks the contact and keeps the research, so the work is not lost. Delete contact removes them and their research permanently. See The approval flow for the full comparison.
They are in the campaign but not sequenced yet
Open the campaign and use Remove on their row. They come out of the campaign without touching anything else.
They are already in sequence
This is the case that catches people out. Kai has pushed them to your outreach platform, and the sending schedule now lives there. Removing them in Kai stops Kai from doing anything further, but it does not always stop mail that your outreach platform has already queued. To be certain someone stops receiving email today, stop them in your outreach platform as well.
A monthly habit worth having
- Add your customer domains. The most common embarrassing send is a prospecting email to an existing customer. One domain rule per customer prevents all of them.
- Add your competitors. They will find their way into sourced lists otherwise, and it is not a good look.
- Add your own domain. Colleagues appear in enriched lists more often than you would think.
- Skim the automatic entries. A spike in unsubscribes on one campaign is a message about the campaign, not about the list.
Who can manage it
Suppression requires a role with sending permissions: manager, admin, or superadmin. Standard seats do not see the Sending tab at all. See Users & roles.
