JANUARY 29, 2024

Subaccount Support in Official SDKs

We have updated our officially supported libraries to include subaccount API operations.

Release notes

JANUARY 25, 2024

Added ARC support to Inbound Messages

We have added ARC headers to all inbound email routed and forwarded by Mailgun. This change was implemented to better align with policy changes at Google and Yahoo.

Also, since we can retain authentication on the forward, DMARC compliance should be retained.

Release notes

DECEMBER 13, 2023

A Subaccount can now send on an IP pool managed by the primary account

We have enhanced the header X-Mailgun-Sending-Ip-Pool to allow a subaccount to send via a primary account-level IP pool. This change was made to support a few different use cases but should remove the burden for primary account users to micro-manage IP allocation on the subaccount level.

Release notes

OCTOBER 23, 2023

New IP Allowlist

Our new IP Allowlist now secures both API and SMTP connections to Mailgun. We have moved the feature into its own navigation item in the settings menu: IP Access Management. Additionally, you are now able to add your own description when creating a new list entry or by updating existing entries.

Release notes

OCTOBER 18, 2023

Global Region Switcher

We have launched a new region switcher in the top navigation of the Mailgun application that quickly and easily allows users to switch between our US and EU region for managing assets.

Release notes

OCTOBER 17, 2023

Reporting Dashboard Enhancements 

For supported plans we have added filters and groupings for both subaccounts and IP Pools.

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.

Release notes

AUGUST 14, 2023

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.

Release notes

AUGUST 10, 2023

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.

Release notes

JULY 31, 2023

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.

Release notes

JUNE 5, 2023

Support for EUR & GBP

Mailgun has released support for payment using EUR and GBP currencies. This will allow new users signing up to choose their preferred currency (USD, EUR, GBP) for billing purposes.

Release notes

MAY 22, 2023

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

MARCH 20, 2023

Logs UI fix

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

Release notes
