When mailfloss finds an invalid email in Constant Contact, the **Cleanup** tab of your Constant Contact integration decides what happens. You have five options. The setting applies to every list in the connection, and you can change it any time.

Before you choose an option, connect Constant Contact to mailfloss. You only do this once. From then on, mailfloss verifies the emails in the [connected Constant Contact](https://docs.mailfloss.com/how-to-connect-constant-contact-to-mailfloss) account automatically.

Here are the five options in the **Cleanup** tab:

**Ask me first.** The safest option. mailfloss lists invalid emails in the **Waiting for you** tab, and nothing changes in Constant Contact until you decide.

In **Waiting for you**, select emails and choose **Unsubscribe**, **Delete**, or **Update custom fields**. You can also mark them **Report incorrect** or **Ignore**, and filter the list by category.

**Unsubscribe.** The recommended option. mailfloss unsubscribes the contact in Constant Contact, so it stops receiving campaigns. You see the contact in the “Unsubscribed” list in Constant Contact. You can resubscribe it in Constant Contact at any time. When you choose this option, mailfloss asks you to confirm. Turn on the switch under **Unsubscribe** to also update the fields.

**Delete from Constant Contact.** Irreversible. mailfloss removes the contact for good, and you won’t find it in Constant Contact anymore. Before this option turns on, mailfloss shows what your last run would have deleted and asks you to type the account name to confirm.

**Update a field.** mailfloss writes the verification result to custom fields in Constant Contact, so your segments can exclude invalid emails. You can also use them to sync with your other databases and CRMs and in automations. This is reversible.

**Report only.** mailfloss emails you a report of the latest floss session. Nothing changes in Constant Contact. Choose this option if you only want the verification statuses for the connected Constant Contact account, like a traditional email validation service.
