Newsletter & Werbung
Marketing email must be clearly identifiable, include a genuine sender, provide a simple unsubscribe option and be sent only to recipients for whom a lawful basis exists.
Compromised mailboxes
If unusual sending activity is detected, the customer must change passwords, check devices, remove unknown forwarding rules and assist Fast4.IT with the investigation.
Blacklists & Beschwerden
Complaints from recipients, providers, abuse desks or blocklists are investigated. Sending may be restricted immediately to protect all customers.
Kundenpflichten
So bleibt Versand sauber
- Use strong, unique passwords and do not share mailboxes.
- Maintain recipient lists, remove bounced addresses and honour unsubscribe requests immediately.
- Do not remove SPF, DKIM, DMARC or MX records without understanding their purpose.
- Coordinate larger mailings with Fast4.IT in advance.
- Respond quickly to warnings or restrictions and resolve the cause.
Sperrlogik
If something looks unusual
Fast4.IT may block messages, impose sending limits, temporarily suspend mailboxes, request supporting evidence, review technical logs and require a clear resolution before approving changes or lifting restrictions.
This is not a penalty; it protects customer data, domains, recipients and the reputation of the shared mail infrastructure.
Kurzfassung
No purchased lists. No deception. No mass-spam risks.
Normal email use is expressly encouraged. Problems arise with advertising that cannot be substantiated, large recipient volumes, spoofed senders, complaints or malicious content. If in doubt, opening a short ticket before sending is the safest approach.
