## What it does

- Sorts your audience into review buckets the moment you open it: hard bounces with the reason they bounced, contacts with no opens in the last 90 days, people who unsubscribed recently, and contacts sitting on an unusually high number of lists.
- Shows each bucket as a checkable table with email, name, lists, tags, and last engagement date, with a running count at the top so you know the size of the problem before you touch anything.
- Lets you select rows and act in bulk: move people to a suppression list, take them off your active lists, or retag them for a later look.
- Protects you from mistakes by never deleting a contact, always moving people to a suppression list first so any decision can be undone, and asking you to confirm the exact count before any action touching more than a hundred people.
- Writes every bulk action to a Google Sheet so you always have a paper trail of who was removed, from which list, why, and when.

## What you'll need

- A Constant Contact account with permission to read contacts and campaign reports and to edit lists and tags
- A Google account with a spreadsheet you want to use as the cleanup audit log
- A rough idea of which lists are your active sending lists, so the app knows what to clean

## Prompt

Build me a list hygiene workspace for Constant Contact that I open about once a month to clean up our audience. Constant Contact has no built in list cleaning tools, so this app is the surface where I review who should be suppressed and then act on it in bulk. It is a recurring ritual, not a one off cleanup, so it should be fast to reopen and should always show the current state of the audience.

The app opens on a single review screen with four buckets, each one a section with a count at the top so I can see the size of the problem before I touch anything. Build the buckets like this. Hard bounces: enumerate recent campaigns with Get Email Campaign Summaries, resolve their activities with Get Campaign Activity, then pull Get Campaign Activity Tracking Bounces for each and show the bounce reason alongside each contact. Dormant contacts: start from List Contacts and check each one with Get Contact Activity Summary over the last 90 days, keeping the contacts with no opens in that window. Recent unsubscribes: pull Get Campaign Activity Tracking Opt-outs across those same recent campaigns. Over-listed contacts: use List Contacts with list_memberships included and flag anyone sitting on an unusually high number of lists, defaulting to more than ten, and note that Constant Contact caps a contact at fifty lists.

Every bucket renders as a checkbox table with columns for email, name, lists, tags, and last engagement date, plus select all and a live count of the current selection. Populate the filter controls above the tables from List Contacts, List Contact Lists, List Segments, and List Tags so I can narrow a bucket to a specific list, segment, or tag before I start selecting.

With rows selected I can apply three bulk actions. Move to suppression list, which uses Add List Memberships (Bulk) against a dedicated suppression list, creating it with Create Contact List the first time if it does not already exist. Pull off active lists, which uses Remove List Memberships (Bulk) for the lists I choose. Retag, which uses Update Contact to apply a review tag such as needs review or re-engage later.

Two rules matter more than anything else and must be baked into the handlers, not just the interface. First, never hard delete anyone. Cleanup always moves contacts to the suppression list before removing them from active lists, in that order, so every decision stays reversible. If the suppression add fails, do not run the removal. Second, any action touching more than one hundred contacts shows a confirmation dialog stating the exact count, the target lists, and the bucket the contacts came from, and only proceeds when I confirm.

The bulk membership endpoints run asynchronously and return 202 Accepted with an activity id, so do not assume the work finished. Poll Get Activity Status until the state is completed and show real progress in the interface, then refresh the affected bucket counts. Surface any per contact failures the activity reports rather than silently swallowing them.

Every bulk action appends an audit row to a Google Sheet using Append Values so there is a paper trail of what we cleaned. Each row records the contact email, which list or lists they were removed from, which bucket they came from, the action taken, who ran it, and the timestamp. Write the audit rows after the Constant Contact activity completes so the log reflects what actually happened, and keep the sheet append non blocking for the user so a logging hiccup never leaves the audience half cleaned without a record.

A few implementation details to respect. Contact subresources like list_memberships and taggings are excluded by default, so request them with the include query parameter when listing contacts. Update Contact is a full replacement, so fetch the contact first, merge the new tag into its existing fields, and send the complete object back rather than a partial patch. Contact listing is cursor paginated, so follow the next link to build a complete bucket. Constant Contact allows roughly four requests per second and ten thousand per day, so batch and throttle the per contact activity lookups and cache bucket results for the session instead of refetching on every render.

## How to customize

- Change the dormancy window from 90 days to whatever matches your sending frequency, for example 180 days if you only email quarterly
- Adjust what counts as too many lists, and decide whether the suppression list is a single catch all or one per reason
- Raise or lower the confirmation threshold from one hundred contacts, or require confirmation on every bulk action regardless of size
- Point the audit log at a different spreadsheet or tab, and add columns like the campaign that surfaced the bounce

## FAQ

### Does this delete contacts from Constant Contact?

No. The app never hard deletes anyone. Cleanup always works by moving people to a suppression list first and then removing them from your active lists, so the contact record and its history stay intact and any decision can be reversed.

### Why clean my list at all if Constant Contact already handles bounces?

Hard bounces are permanent failures, and repeatedly mailing addresses that can never receive your email drags down your sending reputation. Constant Contact does not ship a dedicated list cleaning surface, so most teams do this by hand across several reports. This app puts the whole review in one place.

### How often should I use it?

Most email teams treat list hygiene as a recurring ritual rather than a one off purge. Once a month is a comfortable rhythm, and every six months is the widely cited minimum. The app is built to be opened repeatedly, not run once.

### What happens if I select thousands of contacts at once?

Anything touching more than a hundred contacts shows a confirmation with the exact count before it runs. Large changes are processed in the background, and the app shows progress while they finish rather than pretending the work is instant.

### Can I undo a cleanup?

Yes. Because suppressed contacts are moved to a suppression list rather than deleted, you can always see exactly who was actioned and add them back. The audit log in your Google Sheet records who was removed, from which list, which bucket they came from, and when.

### Why does the app flag contacts who are on a lot of lists?

Constant Contact caps a contact at fifty lists, so people accumulating memberships are usually a sign of overlapping imports or segments that were never cleaned up. Those contacts often get mailed more than you intend, which is a common unsubscribe driver.
