Sendy + Postmark Broadcast Streams (SMTP)
Hello,
Postmark have recently opened up the ability to use their services for 'broadcast' messages.
I can see that in Sendy I can setup SMTP as a method for sending msgs.
Here is what postmark say about setting up SMTP for them:
SMTP
To send with Broadcast Message Streams via SMTP, it requires the ability to add additional Headers with your SMTP client. The X-PM-Message-Stream header is your Broadcast Message Stream ID.
Server: smtp-broadcasts.postmarkapp.com
Ports: 25, 2525, or 587
Username: server token
Password: server token
Authentication: Plain text, CRAM-MD5, or TLS
Header: X-PM-Message-Stream: broadcasts
As you can see it requires the ability to add additional Headers with the SMTP client (sendy).
How can I configure this in Sendy to do this?
Thank you.

Would love to see support for this in Sendy. With a feature to add custom headers it could be useful for other purposes too.
Dying for this to be supported, as well.
Did I see the latest 6.0 update today now allows sending from any SMTP service? Does that mean Postmark is finally supported?
I use postmark as well, so I upgraded to v6, and tested it successfully today. We can't yet set custom headers it appears, so Sendy just sends from postmark's "default transactional stream".
I meant to say this but forgot: it works, but, it's not integrated. That is, you need to go to postmark to see details about the send, because sendy is not capturing the results of each send via postmark's smtp mechanism. FYI
still not possible?
I can confirm this works now. The trick is to change the authentication method in Postmark. You need to authenticate with an SMTP token. Here are the rough steps:
(1) Go to your Server and it's broadcast stream (usually Default Broadcast Stream, although you can change the name)
(2) Scroll towards the bottom and look for "authenticate with an SMTP token".
(3) Use the "Generate an SMTP Token" button. This will create an Access Key and Secret. Note: The Secret will only appear once, so make sure to copy it.
(4) Make a proper selection in Unsubscribe Management. If you select "Manage unsubscribes with Postmark", an unsubscribe link will be automatically added by Postmark to your emails. It's a nice safety mechanism since Sendy allows you to send out a newsletter with only a reminder to include an unsubscribe link. But if you choose this option, unsubscribes will not automatically happen in Sendy.
(5) Save your changes and you are ready for the final step.
(6) Enter the Postmark Access Key and Secret as the Sendy username and password respectively under SMTP Settings for the brand and Save changes. You should be good to go at this point.
