Inbox and Deliverability Check

Not every email address is connected to an active inbox. Some addresses may exist in theory but cannot receive messages. EasyEmailAPI performs deliverability checks to help ensure emails reach real, active inboxes.

Why inbox validation matters

Sending emails to non-deliverable inboxes leads to:

  • Wasted send volume
  • Higher bounce rates
  • Reduced sender reputation
  • Lower engagement

Deliverability checks help avoid these issues before emails are sent.

These checks are available on paid plans and are designed to balance accuracy with performance.
