1. Scope
This Anti-Spam Policy sets out the rules applicable to the sending of emails (transactional, promotional, bulk) through services provided by Rollin Host, including hosting plans with SMTP, corporate email, VPS with a mail server, and any channel originating messages from our infrastructure or from domains under our DNS management.
Rollin Host maintains a zero-tolerance stance on spam: we are signatories to the principles of the MAAWG (Messaging Anti-Abuse Working Group) and follow international best practices (CAN-SPAM Act, GDPR, LGPD).
2. Definitions
- Spam: a commercial message sent in bulk without the prior, express and specific consent of the recipient.
- Opt-in: the act by which the recipient expressly authorizes the receipt of messages from a brand/sender.
- Double opt-in: email confirmation (confirmation link) after the initial opt-in. Recommended standard.
- Opt-out: the act by which the recipient withdraws prior authorization. Must be honored within 72 hours.
- Dirty list: a list of email addresses purchased, rented, scraped or obtained without consent. Prohibited.
- Bounce: rejection of the email by the recipient server.
- Reputation: score assigned by providers (Gmail, Outlook, etc.) to the sending IP/domain.
3. Anti-spam principles
The Customer undertakes to:
- Send messages only to recipients who have granted express consent specifically to receive communications of that nature.
- Maintain an auditable record of consent (date, time, IP address, form, content of the checked box).
- Clearly identify itself as the sender (name, company name, tax ID, physical address).
- Accurately indicate the nature of the message (transactional, promotional, newsletter).
- Provide an opt-out mechanism that is visible, free of charge and actionable in 1 click in every promotional message.
- Process opt-outs within 72 hours.
- Not send to recipients who have flagged a spam complaint or triggered a hard bounce.
4. Mandatory opt-in
Every recipient must have granted express consent to receive emails. The following are prohibited:
- Lists that are purchased, rented, inherited through merger/acquisition without a new opt-in, or scraped (scraped) from public websites, social networks or LinkedIn.
- Lists obtained at conferences, trade shows or events without express and specific opt-in for the type of message.
- Registrations via co-registration without double confirmation.
- Lists generated by email harvesters, scrapers or combinatorial address generators.
We strongly recommend using double opt-in (confirmation link in the first email). It reduces spam complaints by up to 70% and protects your domain reputation.
5. Technical sending limits
The limits below apply to plans without a dedicated SMTP upgrade:
| Plan | Per hour | Per day | Concurrent connections |
|---|---|---|---|
| Shared hosting | 200 | 500 | 5 |
| Essential Email | 500 | 2,000 | 10 |
| Sync Email / Exchange | 1,000 | 5,000 | 20 |
| Standard VPS | 1,500 | 10,000 | 30 |
| VPS with dedicated SMTP | negotiable | negotiable | negotiable |
For higher volumes or bulk sending (legitimate campaigns with opt-in lists), the Customer must engage a specialized ESP (Amazon SES, Mailgun, Resend, SendGrid) or request a dedicated SMTP plan at juridico@rollinhost.com.br.
6. SPF, DKIM and DMARC required
For domains sending more than 50 emails per day via Rollin Host, configuring the following is mandatory:
- SPF (Sender Policy Framework) — a TXT record authorizing the IPs/services allowed to send on behalf of the domain.
- DKIM (DomainKeys Identified Mail) — a cryptographic signature applied to outbound emails.
- DMARC (Domain-based Message Authentication, Reporting & Conformance) — a policy for handling messages that fail SPF/DKIM, with a reporting address.
Since February 2024, Gmail and Yahoo have required SPF + DKIM for any sender dispatching more than 5,000 emails per day, and DMARC with a minimum policy of p=none. Non-compliant messages are rejected or marked as spam by recipient servers — beyond Rollin Host control.
Step-by-step guides are available at /docs/painel/email-imap-smtp.
7. Prohibited conduct
The following are strictly prohibited:
- Sending messages with deceptive content in the subject, sender or body (From, Subject and Reply-To must be accurate).
- Forging headers (From, Return-Path, Received) or using third-party domains without authorization.
- Sending phishing, fraud, advance-fee scams, fake invoices, government impersonation, etc.
- Distributing malware or links leading to malicious websites.
- Sending to recipients who have unsubscribed, filed a spam complaint or appear on suppression lists.
- Sending messages with a disproportionate rate of spam complaints (above 0.3%) or hard bounces (above 5%).
- Operating bulk mailing services (mass sending provider for third parties) on plans that do not explicitly include that authorization.
- Hosting email lists for sale, rental or transfer.
8. Reports and blocklists
Rollin Host actively monitors:
- Sending volume and patterns in real time.
- Feedback loops from major providers (Gmail, Microsoft, Yahoo, AOL, UOL).
- Inclusion of our IPs on public blocklists (Spamhaus SBL/CSS/XBL, Barracuda, SORBS, Senderbase, etc.).
- Abuse reports received at abuso@rollinhost.com.br or /reportar-abuso.
If a Rollin IP is placed on a blocklist due to the Customer, the Customer is responsible for all remediation costs (delisting fees, potential migration to a new IP) and for any damages caused to other customers sharing that IP.
9. Sanctions
Applicable cumulatively according to severity:
- Warning and remediation within 24 hours (first minor violation).
- Temporary suspension of email sending (1-7 days).
- Immediate suspension with no set end date, in cases of phishing, mass spam or critical blocklist listing (Spamhaus SBL).
- Forced migration to isolated outbound SMTP (technical penalty to protect the reputation of other customers).
- Contract termination without refund and block on future sign-ups.
- Recovery of damages from the Customer (delisting fees, reputation loss) and from third parties harmed.
- Reporting to authorities in cases of fraud, phishing or cybercrime.
10. Resellers and end customers
If the Customer is a reseller (reseller plans) or hosts multiple sites/clients:
- It must pass this Anti-Spam Policy on to its end customers.
- It is jointly and severally liable for violations committed by its end customers, without prejudice to its right of recourse.
- It must maintain an abuse reporting mechanism and respond within 24 hours to complaints from Rollin Host.
