Sep 14th 2025

  • Added an option to the /email/* endpoints to allow a schedule timestamp to be passed allowing emails to be scheduled for sending up to 3 days from the request time. A maximum of 10,000 queued emails at a time are currently allowed and emails will be sent as close to the scheduled time as possible.

Aug 15th 2025

  • Added a PATCH /api_keys/edit endpoint that allows for editing of API keys ignoring missing properties instead of defaulting them.

Aug 1st 2025

  • We enabled Keep-Alives by default to speed up TLS handshakes for subsequent requests, If you want to explicitly request the connection to close please pass the Connection: close header with your requests.

July 1st 2025

  • All webhook endpoints can now operate on subaccounts by passing the subaccount_idwhen making requests.

June 12th 2025

  • Marked spam_rejects and bounce_rejects as deprecated (these fields will continue to be returned however)
  • Added a rejects property as the above 2 shared the same information which was a little confusing.

May 28th 2025

  • Reverted a change to the /email/send validation layer that was invalidating payloads with a text_body value of only spaces.

April 7th 2025

  • Added default_ratelimit_value and default_ratelimit_period to /api_keys and /users/smtp responses.

April 3rd 2025

  • Added description to the /stats/email_history endpoint and removed it from the username field data.
  • Removed feedback_domain from the /users/smtp* endpoints as it's no longer required.
  • Fixed an issue with /api_keys/edit where omission of the endpointsproperty would result in the list being overwritten with the default of ["/email/send"].
  • Modified the return value of the custom_ratelimit_period returned from the /users/smtp/(add|edit|view) endpoints to be the same as the /api_keys/(add|edit|view)endpoints to keep them the same.
  • Updated the email_password validation to accept passwords with a given entropy of 64 bits or more, generated passwords will have an entropy of 128 bits or more to improve SMTP security.

January 23rd 2024

  • Modified url description on /archive/search endpoint from A url that can be used to download the attachment to A url that can be used to download the original email
  • Added a custom_headers property to the /activity/search endpoint that allows for specifying headers to parse out of the raw email headers into a more usable structure.
  • Added a sender_full property to the /activity/search endpoint that allows for the full sender information (ie. Joe Blob <[email protected]>) to be accessed if present.
