Setting the fields the hygiene rules name is the only change it makes anywhere. That sentence bounds the agent more tightly than any harness choice could, and it leaves OpenClaw with a job that is mostly following your written rules. NoClick handles the hosting and the credentials on both sides.
Run a staged conversation — no account needed. The agent handles it for real while a simulated world answers its tool calls; nothing touches real accounts, and nothing is actually sent.

List hygiene rules
What a hard bounced address should become in HubSpot: which field to set, to which value, and where the bounce details get written. The agent only ever makes the changes this names.
Alert criteria
Which bounces are worth interrupting someone for, for example a paying customer domain, a VIP account, or more than five bounces on one domain in a day. Everything else stays silent.
Runs on OpenClaw
Preselected for this page — connect your OpenClaw account during setup, or switch to NoClick's built-in models with one click.
Watch it handle a test run
A staged conversation against a simulated world — then it’s live.
Which field, which value, where the bounce details are recorded: all of it comes from a variable you write in plain words.
Bounces fire at any hour and get handled without anyone running a script or watching a queue.
Whoever owns list hygiene, since the two variables are a hygiene policy and an alert threshold rather than anything technical. The connections are Mailgun, HubSpot and one Slack channel, set up once in the Setup tab. Changing what a bounce does to a contact is a text edit, not a rewiring job.
Free to start. Guided setup, a test run against staged conversations, and it's live.
