Why You're Seeing "Unreceived" in Your Deliverability Test

Common Mistakes to Avoid

Not including the seed email address: The seed email address is a unique email address that identifies you as the sender of the test email. It allows email service providers (ESPs) to track your test and generate accurate deliverability results.

Important: Including the seed email address is required.
Always send it together with the rest of the recipient email addresses. 

Sending each email separately: This is one of the most common mistakes and should always be avoided. If you send each email individually, the seed email address will not be included in the same email, making it impossible for us to locate and analyze your test results.

Avoid creating campaigns on platforms: For the same reason, avoid creating deliverability test campaigns through platforms such as Salesforce, HubSpot, or Mailchimp. These platforms typically send a separate email to each recipient instead of a single email to all recipients, which prevents the seed email address from being visible in the test and makes the results unavailable.
