About PCIO VIS Mailings with Postmark
From the official readme · v1.0.0Description
PCIO VIS Mailings with Postmark is an extension for the PCIO VIS Member Event plugin. It routes member mailings and newsletters through the Postmark transactional/broadcast e-mail API instead of the default wp_mail() mailer.
When a Postmark server token and a verified sender address are configured, the Mails page sends via Postmark’s batch endpoint — with attachment support and automatic chunking to stay within Postmark’s payload limits. When the settings are left blank, the plugin does nothing and sending falls back to the standard WordPress mailer, so the Mails feature always works.
Settings are managed under Vis → Postmark in the WordPress admin.
This plugin requires the PCIO VIS Member Event core plugin to be installed and active.
Deleting the plugin from the Plugins screen removes the Postmark settings (API token, from address and from name) it stored; deactivating alone leaves them in place.
External services
This plugin connects to the Postmark email-delivery API (operated by AC PM, LLC / ActiveCampaign) to send member mailings — but only when you have entered a Postmark Server API Token and a verified From Email under Vis → Postmark. If those settings are left blank, no data is ever sent to Postmark and mailing falls back to the standard WordPress mailer (wp_mail()).
What is sent, and when:
- When: each time an administrator sends a mailing from the Mails page while Postmark is configured. Nothing is transmitted during normal browsing or admin use.
- Where:
https://api.postmarkapp.com/email/batch(over HTTPS). - What: the recipient email addresses of the selected members, the message subject and HTML body, any attachments you added to the mailing, your configured sender name and address, and your Postmark Server API Token (sent as an authentication header).
Because member email addresses and message content are transmitted to a third party, please make sure your own privacy policy covers this processing. By using this integration you accept Postmark’s / ActiveCampaign’s terms and policies:
- Terms of Service: https://postmarkapp.com/terms-of-service

Frequently asked questions
What happens if I don’t configure Postmark?
Nothing changes — member mailings fall back to the standard WordPress mailer (wp_mail()).
Where do I get a server API token?
From your account at postmarkapp.com. Use a Server token, not an account token.
Why did a mailing fail to send?
The sender address must be a verified sender signature or domain in your Postmark account. Check Vis → Postmark for the current status.
