Email delivery

Postmark email marketing from your CRM.

GuardenerAI connects to Postmark to deliver your email campaigns and journey messages through your own Postmark account, while consent, unsubscribes and suppressions are handled in GuardenerAI before anything is handed over.

Part of the Marketing module, which is switched on by default for new workspaces. An admin adds the sender under Marketing, Channels.

What it does

  • Sends email campaigns and journey emails through your Postmark account, from the from-address and name you set.
  • Every send passes GuardenerAI’s checks first: consent for the channel and topic, the suppression list, and your frequency policy and daily cap.
  • Adds unsubscribe headers to marketing email, and the message carries an unsubscribe link to a public page.
  • Sends through Postmark’s broadcast message stream by default, the stream Postmark requires for bulk email.
  • Hard bounces and spam complaints reported by Postmark’s webhook suppress the address automatically.

How to connect it

  1. In Postmark, set up a server with a broadcast stream and copy the server token.
  2. Open Marketing, Channels, choose Add sender for email, and pick Postmark.
  3. Enter the from-address and server token, and test the sender.
  4. For bounces and complaints, add a webhook in Postmark with a username and password, and enter the same pair on the sender.

What it does not do

  • GuardenerAI does not create or manage your Postmark account, domain or sending reputation; you set those up with Postmark.
  • This connection is for marketing email. One-to-one email from a record goes through a connected mailbox instead.
  • Postmark’s transactional streams refuse bulk email, so use a broadcast stream.

FAQ

Fair questions.

Why send marketing email through Postmark instead of my mailbox?
Bulk email from a personal mailbox is limited by your mail provider and can hurt the reputation of the address you use every day. A delivery provider such as Postmark is built for volume, and GuardenerAI still applies consent and suppressions before each send.
Can I use more than one email provider?
Each marketing sender names one provider. You choose the sender a campaign or journey sends through, so different senders can use different providers.
Which Postmark stream should I use?
A broadcast stream. That is the default, and Postmark requires it for marketing email.
