Upload and clean your list
Make a list, upload your contacts as a CSV, check the columns and confirm consent. Every address is cleaned on the way in, then checked with its own mail server.
Old lists are full of dead and mistyped addresses. Send to them and inbox providers start treating all of your mail as suspect. So every address you upload is cleaned on the way in, then checked with its own mail server, before a single email goes out.
You'll need your contacts in a spreadsheet saved as a CSV file. Any spreadsheet program or old email system can save one.
Make the list
Open Lists from the menu.
Press New List.
Give it a name you'll recognise.
Press Create List.
Upload your contacts
Choose your CSV file.
Before anything is saved, broken addresses are dropped, duplicates are removed and names are tidied up. Press Continue to mapping.
Check the columns. They're matched for you: email, first name and last name.
Tick to confirm that everyone on the list asked to hear from you.
Press Import.
Bought or scraped lists aren't allowed. They're the fastest way to the spam folder, for you and for everyone sending with you.
See what was cleaned
The import finishes in seconds and shows what happened: how many rows came in, how many were imported, and how many duplicates and broken addresses were left out.
Every import is kept on the list, so you can always see what came in, and when.
Then every address is checked with its own mail server. The ones that fail are never mailed.
What's left are the people your campaigns will reach.
You don't need to clean a list before you upload it. Upload it as it is: the dropping, the checking and the counting are done for you.
