Understanding Email Deliverability

Understanding email deliverability in Re-Leased — explains the Delivered, Delayed, and Rejected states, how to resolve spam and quarantine issues, how to whitelist Re-Leased's IP address, and how to handle DMARC policy failures.

Updated over 2 weeks ago

Emails sent from Re-Leased result in one of three delivery states: Delivered, Delayed, or Rejected. This article explains what each means and how to resolve common issues.


Delivered

Most emails will be marked as Delivered. If a recipient reports not receiving a Delivered email, ask them to check their spam folder. Their IT administrator may also need to check whether the email was quarantined on their mail server.


Delayed

Emails can be temporarily delayed due to the recipient's mail server settings or temporary unavailability. Re-Leased continues retrying delivery for up to 72 hours — there is no need to resend during this period.


Rejected

Rejection can occur if the email address is incorrect or outdated, the recipient's inbox is full, or the email is classified as spam. Check for typos and confirm the address is current. Ask recipients to mark Re-Leased emails as not spam to prevent future misclassifications.


Whitelisting Re-Leased's IP Address

If the recipient's security policies block Re-Leased emails, their IT administrator can whitelist our IP address 167.89.19.59 to ensure delivery.


DMARC Policy Failures

If emails fail DMARC compliance checks, the sender's SPF record may need updating. IT administrators can contact Re-Leased Support for guidance. See also: SPF Records Explained (Twilio SendGrid).
