Sending Mail (SMTP) with Your Virtual Machine

By default, SMTP (Simple Mail Transfer Protocol) is blocked on all virtual machines in the Rumble Cloud environment. This policy helps to prevent email abuse.

Rumble Cloud is committed to maintaining a secure and reliable platform for all users. Sending spam is strictly prohibited and may result in the suspension or termination of your account. Unsolicited mass emails and spam violate our terms of service and undermine the trust and integrity of our community.

If you need to send emails from your VM using SMTP, you can request access by opening a support ticket. Please follow the steps below carefully to make sure your request is processed as quickly as possible. Note that if you are sending mass emails (i.e. mailing lists), please refer to our compliance section below.

Step-by-Step: Requesting SMTP Access

To enable SMTP for your virtual machine, you’ll need to open a support ticket at https://portal.rumble.cloud/help and include the following information:

  • Virtual Machine Details
  • Name or ID of the VM you want to use for sending SMTP traffic.
  • IP Address
  • The public IP address that your VM will use to send email.
  • PTR Record (Optional)
  • Do you want us to create a PTR (reverse DNS) record for your IP address?
    • If Yes, include the domain name that the PTR record should point to.
    • If No, you can skip this part.

Example Support Ticket

Here’s a sample you can copy and customize:

Subject: Request to Enable SMTP for Virtual Machine

VM Name/ID: vm-prod-001
Public IP Address: 123.123.123.123
PTR Record: Yes
PTR Domain Name: mail.example.com

Important Notes

  • SMTP access is granted on a case-by-case basis to prevent spam and misuse.

  • Make sure your DNS settings match your PTR records for best deliverability.

  • Allow up to 24–48 hours for the support team to process your request.

Compliance Guidelines for Mass Email Sending

Compliance with Email Regulations

When sending mass emails, you must ensure that your communications comply with all applicable laws, rules, and industry standards. This includes, but is not limited to, the following requirements:

  • Opt-In Consent: Only send emails to recipients who have explicitly opted in to receive communications from you.
  • Clear Unsubscribe Mechanism: Every mass email must include an easy-to-find option for unsubscribing. Recipients should be able to opt out quickly and without barriers.
  • Accurate Sender Information: Ensure that your contact details and sender information are accurate and match the expectations set with your subscribers.

Failure to adhere to appropriate guidelines and requirements may result in the suspension or termination of your account.

Best Practices for Sending Mass Emails

Following these best practices helps you maintain a healthy sender reputation and ensures your messages reach the intended audience:

  • Collect Explicit Permission: Build your mailing list with users who have clearly given their consent. Avoid purchasing or using third-party lists.
  • Segment Your Audience: Organize your recipients based on interests, behavior, or demographics to deliver more relevant content.
  • Monitor Engagement Metrics: Keep an eye on your bounce rates, open rates, click-through rates, and unsubscribe rates to gauge the performance of your campaigns.
  • Maintain an Up-to-Date Mailing List: Regularly remove inactive or bounced email addresses from your list.
  • Use a Consistent Sending Schedule: Establish a regular cadence for your emails to avoid overwhelming your recipients.
