Send this to your assistant

Create a ClickRuntime automation: every day at 8am, email me the addresses that bounced yesterday on each of my Campaign Monitor lists, grouped by list.

Paste it into your assistant. It tells you what it will send or change before it runs live.

First time? Adding ClickRuntime to your assistant takes about two minutes.

Why use it

Why teams use this automation

Anyone who sends newsletters through Campaign Monitor knows the slow damage of a dirty list. People change jobs, mailboxes fill up and domains lapse, and each bounced address counts against the sender's reputation. Left alone for months, a list full of dead addresses pushes more mail into spam folders, and the readers who do want your emails stop receiving them without anyone noticing.

Every morning, ClickRuntime asks Campaign Monitor for the subscribers that bounced since yesterday, list by list, and emails you one tidy digest of addresses and lists. You can remove or correct them while the cause is recent. The digest is a short daily to-do for list hygiene.

List owners at agencies, associations and small publishers, who manage several lists at once, find it most helpful. Small lists benefit as much as large ones, because a few bad addresses hurt a small sender quickly.

What you get out of it

  • Sender reputation is protected daily

    Removing bounced addresses promptly keeps your bounce rate low, which mailbox providers watch closely. A clean list means your campaigns keep landing in inboxes instead of spam. Healthy standing with mailbox providers is slow to build and quick to lose, which makes daily housekeeping worth the minute it takes.

  • Lost customers can be reached another way

    A bounce on a client address often means the person left or changed domains. Seeing it the next day lets an account manager find the new contact before the relationship goes cold.

  • List cleaning becomes a small daily habit

    Handling a handful of addresses each morning is easy. Waiting for a quarterly cleanup means thousands of dead contacts and an afternoon of tedious work. Fixing a typo the same week means the subscriber still gets the welcome message they were promised.

  • Typos at signup get corrected

    Some bounces come from a mistyped address on a form. Spotting them quickly gives you the chance to email the person another way and fix their record so they receive the welcome message.

  • Data for form and import problems

    A sudden burst of bounces after a list import points to bad source data. Seeing it the very next morning lets you stop the problem before it harms the next campaign.

How it works

What happens, step by step

  1. Once a day, ClickRuntime goes through each of your Campaign Monitor lists.

  2. For each list it collects the email addresses that bounced yesterday.

  3. If there were any bounces, you get one email grouped by list, with the addresses ready to remove.

Build your own

Need it to work differently?

This template is a starting point. Copy the prompt and change it, or describe a different automation from scratch, with your own conditions, more apps or an AI step. Your assistant writes it, tests it and runs it on ClickRuntime.
  • Your own rules

    Conditions, thresholds, filters and exceptions, written the way you'd explain them to a colleague.

  • Any number of apps

    One automation can read from one app and update several others. Over 248 apps are ready, and anything with an API works too.

  • AI where it helps

    Summaries, classification, extraction and drafts use ClickRuntime's built-in AI, with no extra key.

  • On a schedule or on each event

    Runs as often as every 5 minutes, or the moment an app sends an event, and keeps track of what it already handled.

Changes you can ask for

  • Run it at a different time, more or less often, or only on weekdays
  • Add an AI step, for example to summarize, sort or draft a reply
  • Add another app, for example also send it to Slack
  • Combine it with other Campaign Monitor steps into one automation

Under the hood

The code that runs this automation

This is the Python script that runs each time the automation starts. Your AI assistant writes it for you when you send the prompt, and you allow each step in your assistant. To change how the automation works, describe the change to your assistant and it updates the script for you. For every function it can use, see the script reference.
bounce_digest.pyexample
from datetime import date, timedelta
from clickruntime import on_trigger, credentials, notify, http

API = "https://api.createsend.com/api/v3.3"
CLIENT_ID = "your-client-id"

@on_trigger
def run(event):
    auth = (credentials.secret("CAMPAIGN_MONITOR_API_KEY"), "x")
    yesterday = date.today() - timedelta(days=1)
    sections = []
    for lst in http.get(f"{API}/clients/{CLIENT_ID}/lists.json", auth=auth).json():
        bounced = http.get(f"{API}/lists/{lst['ListID']}/bounced.json", auth=auth,
                           params={"date": yesterday.isoformat(), "pagesize": 1000}).json()["Results"]
        emails = [b["EmailAddress"] for b in bounced if b["Date"].startswith(yesterday.isoformat())]
        if emails:
            sections.append(f"{lst['Name']} ({len(emails)})\n" + "\n".join(emails))
    if sections:
        notify.email_me(f"Campaign Monitor bounces on {yesterday}", "\n\n".join(sections))
    return {"lists_with_bounces": len(sections)}

FAQ

Common questions

Does it remove bounced subscribers from my list?
No. The digest only reports them, so you decide what to do. Campaign Monitor already suppresses hard bounces from future sends in its own way, and this email helps you correct records, update your CRM or contact the person.
Which bounces are reported?
It lists subscribers Campaign Monitor reports as bounced since the previous day for each list you include. Whether soft and hard bounces appear together depends on what the API returns for the list, and the digest shows what it receives.
Can it cover all my lists in a client account?
Yes. The workflow can loop through every list in the client account or only those you name. Agencies with several clients can run one setup per client. Tell your AI assistant which lists to include and review the plan.
What permissions does it need?
API key. Nothing else in your accounts is used.
Does it need AI?
No. It runs without AI, so it doesn't use your plan's AI allowance.
How many runs does it use?
One run each time it runs (daily). Checks that find nothing to do and stop right away aren't counted.
Can I change how it works?
Yes. Describe the change to your AI assistant, for example a different schedule, channel or filter. It updates the automation, tests it and tells you what changed.
