Seed Based Email Tests: Best Practices
A seed based email test involves sending a message to a list of test email addresses set up with different inbox providers. Such a list is called a seed email list. At GlockApps, the seed list contains 100+ email addresses utilized specifically for Inbox Insight tests.
However, sending a message to 100+ email addresses at a time may be unsafe for your sender reputation especially if you have a new domain or a domain without a sending history behind it.
