Acceptable use policy

Scannable summary: Opt-in recipients only • Zero tolerance for spam or purchased lists

MailBlaster enforces a strict anti-spam mandate to protect global deliverability and domain sending reputations. By checking our agreement box upon registration, you agree to adhere unconditionally to the three straightforward rules below.

1. Explicit affirmative opt-in recipients only

You may only send email broadcasts to individuals who have explicitly and actively opted in to receive communication from your organization. Passive consent, pre-checked signup checkboxes, or verbal agreements are not acceptable forms of verifiable consent.

2. Strictly prohibited contact lists and practices

You must never upload or transmit campaigns to the following types of recipient data:

Purchased or rented contact listsBuying, leasing, or borrowing email lists from brokers, lead databases, or third-party aggregators is entirely prohibited.

Scraped and harvested emailsGathering email addresses utilizing automated extraction bots from public websites, forums, or social networks is forbidden.

Cold outreach and unsolicited sales prospectingMailBlaster is an opt-in broadcast platform, not a cold-emailing or unprompted cold prospecting tool. Do not email strangers without prior consent.

3. Enforcement: Immediate account suspension without refund

Our automated telemetry monitors delivery metrics in real time. Workspaces that exceed industry thresholds for hard bounces (>5%), spam complaints (>0.1%), or that violate this policy will face immediate account suspension without refund.
