Release notes
SEPTEMBER 18, 2023
Increased message scheduling window
Mailgun has increased the max scheduling window for messages from 3 to 7 days. The scheduling window is based on the plan's message retention, i.e., Foundation message retention is 1 day, so the max scheduling window is 1 day. Scale message retention is 7 days, so the max scheduling window is 7 days.

Subaccounts
We have officially released our long-anticipated subaccounts feature. We hope to assist a number of user cases that need self-provision and segment Mailgun accounts based on business unit, email type, or serving your own end-users. Please note that the subaccounts feature is currently reserved for contract customers.

API key management update
Mailgun has launched a long-anticipated upgrade to our API key management system that allows the creation of multiple API keys for users who are managing multiple applications. We also upgraded the security of our keys, meaning they will be hashed in our database, and we will be unable to display them in plain text once generated.
Release notes
AUGUST 8, 2023
Accepted Webhook
Mailgun will now push an event data payload to your URL when Mailgun accepts the request to send/forward the email and the message has been placed in queue.

Mailgun Shared IPs Now Dynamically Assigned
We have implemented changes to affect how Mailgun shared IPs are allocated to sending domains. When a sending domain is only using shared IPs, these IPs are no longer explicitly assigned to the sending domain. The sending domain will use shared IPs designated at send time. As such, the UI will not show explicitly assigned shared IPs.
Release notes
JULY 14, 2023
Allow for tracking pixel to be placed at top of email
We have added the option to place a tracking pixel at top of email. This is to assist senders that may be sending large emails that are only being partially rendered/displayed at the recipient causing inaccurate engagement rates when tracking pixel is by default located at the bottom of messages.
See our documentation on the setting as well as an API reference on the new parameter.
Release notes
JULY 6, 2023
DKIM Keys management
We've launched the ability to manage up to 3 active DKIM keys for a sending domain which will allow a user to manually rotate their DKIM key, or upgrade their key(s) from 1024 bit to 2048 bit keys without having to delete and re-add a domain. See our Help Article here: How do I rotate my DKIM key? or our API docs at Domains — Mailgun API documentation for more information.
Release notes
JUNE 12, 2023
Updates to Templates
We've added the following updates to our Templates offering:
Ability to store headers (Subject, From-address, Reply-to address) directly on a template, which will allow you to send a message providing just the recipient and template name.
Removed limitations in template name that prevented the use of capital letters, spaces and special characters (template name is now encoded)
Fixed an issue where templates that included some Handlebars helpers were not rendering in the Mailgun application.

IP Pools UI Update
We've released the ability to view and manage linked domains on the Edit IP Pools modal located at https://app.mailgun.com/app/account/ip-pools/list.
Release notes
MAY 11, 2023
'HTMLonly' option for open tracking retired
Mailgun has retired the 'htmlonly' open tracking setting and has removed the option from our API and application. This was a legacy setting that had low adoption and should have an extremely low impact on customers.
Release notes
APRIL 20, 2023
Get IP Pool details API call
We released a small update to our /ip_pools endpoint to allow a user to issue a GET call to https://api.mailgun.net/v1/ip_pools/<pool_id> to be able to retrieve information about the IP Pool such as which IPs and domains are associated with that IP Pool, along with the usual name and description.
Release notes
APRIL 18, 2023
Manually input SMTP Password via UI
UI updated to support manual creation of SMTP password when creating a new credential or resetting password for SMTP login previously created. While it is recommended to use the more secure, auto-generated password, some use cases needed the character count of the password to be shorter.
Release notes

Fixed Resend message modal from Logs page to pre-populate original recipient address. Removed non-relevant placeholder text.
