Back in March 2018 we released modular webhooks, allowing you to choose which events you’d like to send to each specified hook URL. Up to now this has only been possible through the UI. We’re happy to announce that we just released a brand new
/webhooks API endpoint, which brings support for the setup and maintenance of modular webhooks, as well as some of the Message Stream functionality we’ve been working on.
The new endpoint lets you list all existing webhook configurations; retrieve a specific configuration; and of course create, update, and delete modular webhook configurations.
Note that at this point we haven’t made any changes to how our
/servers endpoints work with regard to webhooks. Setting/updating webhooks via that endpoint will continue to set a single hook for your default transactional stream. We plan to update this in the future, but we’ll give you plenty of advance notice when that happens.
We wanted to let you know about a few changes we’re making to SMTP sending in the coming weeks to make this endpoint more secure. These changes will only affect sending via SMTP. If you use only the Postmark REST API to send, no further action is required on your part.
The following changes will be made to our supported SMTP TLS configuration:
We understand that this type of change can be disruptive, so we want to provide you with ample time to test and verify that your application will be able to continue sending mail using the updated security settings.
These are the key dates for these changes:
The most significant change, which might affect you, is that we are disabling TLSv1 on December 14, 2019. This protocol is old and vulnerable, so we will be rejecting connection requests that use TLSv1.
Before the cutover date on December 14th, 2019, we recommend that you perform some tests against the following temporary testing endpoint:
future-smtp.postmarkapp.com. This endpoint matches the changes we’ll be making, so if everything works as expected, you’re good to go. Just switch back to using
smtp.postmarkapp.com and no further action will be needed.
If you run into any issues using the temporary endpoint (i.e., your SMTP client is unable to connect), please contact our support team and let us know what OS and SMTP client you’re using to connect. We may be able to provide specific instructions for using newer TLS configurations.
Once again, we are going to disable TLSv1 on December 14, 2019. Please perform all testing and make any necessary code changes before this date.
Please let us know if you have any questions about these changes.
Our template comparison tool now lets you review code changes and quickly navigate between templates. This tool is available when pushing templates between servers.
We have added the following IPs to our SMTP endpoint service. If you send email using SMTP and explicitly whitelist our SMTP endpoint IPs, these will need to be added:
Today we are releasing the first in a series of product changes to get us to the point where you can send all your email through Postmark. This release introduces the concept of Message Streams to the Postmark UI.
A Message Stream is a way to organize and separate your sending within a server. We know that some people use servers as environments, while others use it to separate clients, apps, etc. Message Streams give you an additional way to separate your sending and reduce the proliferation of servers on your dashboard.
Check out our blog post for all the details.
We released a bunch of improvements to MailMason's workflow. This includes the ability to push your templates up to Postmark as well as general maintenance and package upgrades. We've also made design and accessibility improvements to the starter templates that ship with MailMason.
We know how frustrating it is to edit common elements like the date in a footer, or a logo, or a design change you want to make across all your Templates. So today we are really excited to announce the release of Postmark Layouts — a way to define commons elements like CSS, Headers, and Footers, and reuse those Layouts across many Templates.
On Monday, May 20th we made a change to the way we process SMTP headers for emails that are sent with SMTP. Please note that this change does not affect sending via the API.
Historically, when Postmark accepted messages over SMTP, we have constructed the
Bcc headers for messages sent to show only the subset of recipients you specify during sending. In some uncommon cases, this behavior meant that not all recipients would be visible in the message that is delivered to your recipients.
With this update, we will ensure that the recipients that are visible in your messages’
Cc headers are the same as what will be shown to the final recipients of your messages. We will no longer reconstruct them based on our older behavior, which, in some uncommon cases, could have prevented some recipients from being displayed in the final email that we deliver.
Read the blog post for full details.
We just released an update to the status page that lets you see the status of each individual service, and also drill down into the response times and past incidents for each service.
Have you been frustrated while trying to use your phone to view your Postmark stats or find a specific email in your activity feed? Us too! So we’re happy to say that the Postmark web app is now — at long last — responsive. Like so:
Please try it out and let us know if you have any feedback!
We will disable support for SSL v3 on March 7th, and going forward our servers will only support encrypted SMTP connections using TLS (1.0 - 1.3). Most customers will not be affected by this change. However, you can double check that your SMTP client is compatible by temporarily sending mail through
future-smtp.postmarkapp.com instead of
future-smtp.postmarkapp.com points to the new servers (and new IPs) and it does not allow SSL v3 connections. If you use connection to test and everything works well, no further action is needed and sending should continue through our current endpoint:
If you are having trouble connecting over
future-smtp.postmarkapp.com you will need to update your SMTP client. Please can let us know if you are not able to resolve or update your SMTP client before the switchover date.
Action Mailbox is a new framework in Rails 6 that routes incoming emails to controller-like mailboxes for processing in Rails. You can get more information about Action Mailbox in the introduction blog post.
We just released an update that lets you push template changes from one server to another. Check out our blog post for all the details.
Our WordPress plugin now supports link tracking! We've also fixed an issue where open and link tracking options were not honored when sending a test email.
We just released an update to the WordPress plugin that adds an optional setting for preserving logs of send attempts. It adds a new Logs tab that can be used to view the last 7 days of plugin sending activity.
Preserving send logs are useful for a couple of reasons:
We heard a lot of feedback from users saying their plugin wasn't working but they had no idea why, and there was not an easy way to tell what was going wrong. Now, you can quickly see what is going on and resolve the more common errors, like trying to send from an address that isn't on your account yet, or trying to send to external recipients before you Postmark account is approved.
We’ve already made a few minor updates based on feedback and additional real-world use, so make sure to grab the latest version. Check out the wiki for more details, including a migration guide for moving from 1.x to 2.x.
You can now for search for a template from the UI. No more sifting through pages and pages of templates to find what you’re looking for!
You can now receive notifications through our Slack app each time we add or update an incident on our status page. Check out the Postmark Slack app page for more details.
Today we released an update to the Postmark iOS app! This release includes:
Today we released some layout updates to our template pages. This first update focuses solely on quick wins at making it easier to manage more templates with longer naming conventions. It also sets the stage for our next updates in the pipeline like template searching and aliases.
Keep an eye out for phase 2 and 3 changes in the coming weeks!
We’ve made tons of design improvements in the Postmark app over the past few months. From a new activity feed, to a better DNS Settings page, all the way through a redesign of our webhook pages, we set out to understand exactly what you need to do on those pages and flows, and design the best possible experience for those needs.
Today, that philosophy gets extended to one of the most-used pages in the Postmark app: the Servers page. You’ve been asking us for a while to add features like search and better sorting options to that page, and today we’re happy to give you that, and much more.
This release includes support for our new metadata feature. You may now include metadata with your outbound messages, and Postmark will include that data in webhook payloads, message details, and message searches. See the full release announcement here.
This release also enables you to specify the BaseURL for each API request, making testing with Guzzle a lot easier.
Finally, you can now enable, or disable SMTP API Error Webhooks for Servers using the Admin Client.
As always, we hope this release helps you get even more value from Postmark, and please feel free to contact us if you have any questions or requests!
Our Swiftmailer Transport for Postmark has been updated with some minor enhancements, and it also now works with SwiftMailer 6.
This release of the official .net client for Postmark includes the addition of the Domains APIs, support for our new custom metadata feature, as well as the “EnableSMTPErrorHook” property to the the Create and Edit Server endpoint methods.
You can now add custom metadata to your emails, and we'll pass that same data back to your system through our webhooks.
We just finished work on a series of small updates to the app that work together to help you pick the pricing plan that's right for you, and make the whole "paying for Postmark" thing a lot more pleasant. Below is an overview of the changes.
Instead of a gauge that shows that you're "in the red" as soon as you hit your monthly limit, we now have a much better indicator with three states:
This will clear up a lot of the confusion about where you're at with your usage.
We've improved the messaging we show when it would be beneficial to you to upgrade.
Our billing emails used to be text, and they're now beautiful HTML templates. We now also tell you if you can save money by upgrading to the next plan.
New users will now see the pricing calculator in the app, so they don't have to leave the app and go to the marketing site to do the calculation.
Repeat config option
To continuously check an email address, add the repeat option to the config object. repeat accepts any number above 5000 milliseconds. We recommend using it sparingly for workflows crucial to email such as account activation or password reset pages.
Check out Rebound’s API docs for more details.
We're constantly improving Postmark and taking care of small issues and annoyances that we find (or you send us!). We wanted to start telling you about these fixes, so from now on we'll update you every few months about the bug fixes and other small tasks we take care of in between our larger feature projects.
Here's a brief overview of all the bug fixes and small changes we completed in April and May of this year:
Email is a critical component of most web applications, and we know how important it is to have tools to investigate and resolve any delivery issues quickly. The Postmark iOS app allows you to take our powerful email monitoring and troubleshooting tools with you wherever you go.
We now disable all the third-party scripts that collect data about users visiting our website if the user has Do Not Track enabled. This includes analytics and A/B testing services, as well as less obvious data collectors like live chat.
Rebound prompts your customers to update their email address if an email you sent them hard bounced.
You can now add multiple webhook URLs for a server and choose which events you’d like to send to each specified URL.
This one has been a long time coming… Today we’re happy to announce that you can now — yes, finally — perform searches on the sender signatures page. No more going all the way to page 594 (yes, some accounts really have that many sender signatures!) to find that one elusive one you’re looking for.
Send Bounce notification messages from Postmark to a Slack channel of your choice. Each notification also provides a direct link to the Message Details page so that you can investigate further.
Postmark now offers monthly plans instead of credits, and the new plans will likely save you money. More importantly, if the new pricing doesn’t save you money, nothing changes.You’re grandfathered. You can continue using credits, and your pricing doesn’t change a bit unless you want it to.
We release a simplified DNS Settings page to make it easier to ensure great delivery for your email. But we didn’t stop there — we also made some backend changes to streamline how we authenticate domains for email sending. Let’s go through some of those changes.
Hot off the heels of releasing advanced user roles and permissions, today we’re giving you a way to add extra security to your account by enabling two-factor authentication (2FA).
For the longest time we’ve only had two types of accounts: a single Account Owner, and separate Viewers. Viewers are only able to view reports, email activity, and receive email digests for the servers they are assigned to. So, today, we’re adding two new roles to Postmark: Account Admins and Server Admins.
You can now add emoji to your Postmark subject lines, and they’ll render correctly in your favorite email clients. Of course, emoji are already supported in the message body, so there are no changes there.
We released some significant updates to the activity feed to increase information density and clarity, upgrade the filtering experience, and add the ability to export the activity feed to a CSV.
We’ve really expanded our documentation. More guides, help docs, blog posts, open source projects, and developer docs. Unfortunately, that proliferation led to fragmentation. So we set aside time to unify all of our documentation into a single home and make it all searchable.
We decided to take our DMARC reports a step further. Instead of just showing you synthesized DMARC information, we now include helpful tips on how to address each of the possible issues you might see on the IP addresses that are sending on your behalf.
Postmark can now notify your application of delivery events via webhooks so you can do a variety of things like feed delivery events into an internal system, provide delivery even notifications to your customers, or aggregate delivery even data to see patterns and respond accordingly.
