Notes — Postmark (ActiveCampaign, LLC — acquired by ActiveCampaign) is a transactional email delivery service for developers. The governing SLA is ActiveCampaign’s published SLA (updated January 30, 2025), which commits to 99.5% availability per reporting period. Credits are applied dollar-for-dollar against the next period’s invoice and must be claimed within 10 business days of the reporting period end. Whether the SLA explicitly covers Postmark as a named service requires verification with ActiveCampaign.
