¶ How to Select a List for Cleaning
There is a dropdown list at the top of the page.
You can select:
- All Contacts (clean the entire database at once).
- Specific List (for example, "Website Subscribers" or "Customers").
¶ What Can Be Deleted
¶ 1. Unavailable Contacts
Addresses that return delivery errors (hard bounce and soft bounce). These include:
- Does not exist — addresses that do not exist or have been deleted.
- Mailbox full — addresses that do not accept emails due to mailbox limit.
- Temporarily unavailable — addresses that do not accept emails at the moment but may become available later.
Tip:
It is recommended to delete non-existent addresses first
¶ 2. Unsubscribed Contacts
Contacts that:
- Unsubscribed themselves from campaigns
- Complained about your emails as spam.
Important!
According to the law and email service rules, such contacts cannot be added back to the list without explicit renewed consent.
¶ How to Clean the Database
- Select a list or the entire database.
- Mark the address categories you want to delete.
- Click the "Delete" button.
- Confirm deletion in the pop-up window.
Deleted contacts will disappear from all lists and will no longer receive your emails.
¶ Important to Know
- Cleaning is irreversible — contacts cannot be restored.
- It is better to perform contact verification regularly, especially if the database is large.
