Acceptable Use Policy

Effective June 3, 2026

Postmark RSVP exists to let real people invite real people to real events. This policy keeps it that way.

Allowed

• Wedding, party, fundraiser, conference, class, club, or other event invitations.
• Lists of people who personally know you or your organization.
• Follow-up reminders to invitees who haven't responded.
• Internal team RSVPs (offsites, meetings, training).

Not allowed

• Purchased, scraped, or rented email lists.
• Marketing, promotional, or sales emails dressed up as RSVPs.
• Adding people who never opted in or never met you.
• Phishing, spoofing, or impersonating another person or org.
• Anything illegal where you or your guests live.
• Adult content, gambling promotions, or regulated-substance sales.

Bounces & complaints

We monitor bounce and spam-complaint rates. Persistent high rates will pause your account while we investigate. Sending to known-invalid addresses isn't a strategy — clean your list first.

Reporting abuse

If you received a Postmark RSVP email you didn't expect, please forward it to abuse@postmark.rsvp. We act on every report.

Enforcement

We'll warn you first when we can. We'll suspend immediately when we have to — for example, ongoing phishing or a complaint storm. Repeat or severe violations end with termination and no refund.
