E-goi makes it pretty easy to remove contacts in your list, but keep in mind you can't easily get them back if you change your mind later! The only way is having us restore your backup, which isn't free.
Another thing: if you've sent a campaign in the last 30 days to the contacts you want to remove, they won't be deleted! You can only do it 30 days after it has been sent out, to ensure they've got enough time to unsubscribe or edit their subscription. Still, if you want them to stop receiving any further campaigns from you right now, you can simply change their status to "Inactive".
On to deleting contacts then:
1) Go to the "Lists" menu and click "Contacts" of the list containing the contacts you want to remove.
2) A page will come up with all contacts in that list. What happens next depends on what you want to do.
Removing one or just a couple of contacts
If you can see the contact you want to remove, simply hit its garbage can icon.
Need to delete multiple contacts instead? Tick the checkbox to the left of each one and click "Actions" in the lower left corner of the page. A window will come up with a list of actions you can perform. Click «Remove» and confirm your choice.
Removing all contacts in the list
Just click "Actions for the whole list" in the lower left corner of the page and then hit "Remove" in the window that comes up. Confirm your choice and you're done!
Removing all contacts in a specific segment
Create or load the segment containing the contacts you want to remove. Then click "Actions for this segment" in the lower left corner of the page and hit "Remove" in the window that comes up. Confirm your choice.
And that's all there is to it! Please note that removed contacts will always remain in your list to prevent them from being accidentally imported later (their status will be "removed"). If you're using one of our monthly plans (which are charged on the number of contacts in your list), don't worry, removed contacts don't count towards your plan total!
