Seed List
Also known as: Seed Addresses, Test Inboxes
A seed list is a small group of test email addresses you add to campaigns so you can see if messages land in the inbox, spam, or other folders before you send to your full list.
A seed list is a set of test inboxes that you include in your sends. These inboxes sit at providers like Gmail and Outlook, along with any other services your audience uses. When you send a campaign, you check these inboxes to see where the email shows up and how it looks.
This matters because it gives you real inbox data instead of guessing from open rates. If seed addresses at one provider all land in spam, you know there is a deliverability issue to fix before you mail your full list. That can protect your sender reputation and keep revenue emails from going quiet.
A simple way to start is to create a handful of test accounts across your main mailbox providers and add them to every important send. After you send, log in and check if the email hit the inbox, spam, or a secondary tab. If you spot a problem, pause broad sends and work on authentication, list quality, or content before trying again.
