Anti-Spam Policy

1. Purpose & Scope of Policy

Dalo Mail is a specialized provider of custom-domain business email hosting, webmail collaboration, and authenticated transactional email infrastructure. The purpose of this Anti-Spam Policy is to preserve the sender reputation of our global IP ranges, maintain sub-second inbox delivery rates across internet service providers (Gmail, Outlook, Yahoo, Apple Mail), and guarantee full compliance with international anti-spam legislation.

This policy applies to all accounts, organizations, employees, and third-party automated systems dispatching emails through Dalo Mail SMTP relays, webmail applications, or REST APIs.

2. Definition of Spam & Unsolicited Email

Under this policy, “Spam” or “Unsolicited Commercial Email (UCE)” is defined as any email message sent to a recipient who has not granted verifiable, explicit, and informed permission to receive communications from your organization.

3. Mandatory Sender Requirements

Every commercial, marketing, or transactional message sent through Dalo Mail must strictly adhere to the following standards:

• Accurate Header Information: The “From,” “To,” “Reply-To,” and routing domain headers must truthfully identify the sender and domain responsible for dispatching the message.
• Non-Deceptive Subject Lines: The subject line must accurately summarize the message body and not employ misleading clickbait, fraudulent urgency, or false promises.
• Clear Physical Address: Commercial communications must include the sender's valid physical postal address or registered business location.
• 1-Click Unsubscribe Mechanism: Bulk communications must feature a clear, functioning 1-click unsubscribe link. All opt-out requests must be processed automatically within 24 hours without requiring the user to log in or enter personal details.

4. Strictly Prohibited Sending Practices

Dalo Mail maintains a zero-tolerance enforcement model. The following activities will result in immediate service termination without refund:

5. Technical Authentication (SPF, DKIM, DMARC)

In accordance with Google and Yahoo 2024+ sender mandates, all custom domains sending email through Dalo Mail must maintain valid cryptographic DNS records:

• Sender Policy Framework (SPF): A valid DNS TXT record authorizing Dalo Mail outbound edge IP ranges to dispatch emails on behalf of your domain.
• DomainKeys Identified Mail (DKIM): Active 2048-bit cryptographic key signing for all outgoing messages.
• Domain-based Message Authentication, Reporting & Conformance (DMARC): A published DMARC policy record (v=DMARC1; p=none or stricter) with configured aggregate reporting tags.

Dalo Mail provides automated 1-click verification of these records in your Custom Domains & DNS console.

6. Live Reputation Monitoring & Heuristics

Our platform integrates automated telemetry and real-time heuristics that continuously monitor outbound traffic for patterns characteristic of automated botnets, compromised mailboxes, or mass spam waves:

• Rate of recipient domain distribution and volume spikes.
• Real-time blocklist checks against major anti-spam intelligence networks (Spamhaus, Barracuda, Invaluement, SURBL).
• Automated feedback loops (FBL) configured with major consumer webmail providers.

7. Deliverability Thresholds & Hard Bounces

To ensure clean IP delivery pools for all customers, organizations must maintain performance metrics within the following thresholds:

• Spam Complaint Rate: Must remain strictly below 0.10% (1 spam complaint per 1,000 sent emails). Reaching 0.30% results in immediate account throttling.
• Hard Bounce Rate: Must remain strictly below 3.0%. Repeated dispatch to invalid or non-existent recipient addresses indicates stale or unverified contact lists.
• Unsubscribe Requests: Must be honored instantly and must not exceed industry normal rates.

8. Automated Throttling & Account Suspension

When our automated systems detect metrics exceeding acceptable thresholds or receive verified complaints from internet providers:

1. Stage 1 (Automated Throttling): Outbound rate limits are temporarily reduced to prevent further reputation degradation, and an urgent alert is dispatched to workspace administrators.
2. Stage 2 (Outbound Suspension): If spam complaints or high bounces persist, outbound SMTP routing is suspended while inbound email delivery remains operational.
3. Stage 3 (Account Termination): Confirmed phishing, malware transmission, or deliberate bulk spam operations result in immediate permanent account termination without refund.

9. Remediation & Appeals Process

If your outbound sending was throttled or paused due to an accidental list anomaly or a compromised mailbox credential:

• Submit an appeal directly to abuse@dalomail.com detailing the root cause of the incident.
• Provide documentation demonstrating how the issue was remediated (e.g. password resets, list cleaning via double opt-in verification, removal of compromised accounts).
• Our deliverability specialists review appeals within 4 business hours and restore sending privileges upon verified resolution.
