SMTP2GO API Changelog

over 4 years ago by Matthew Smith

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.
