It is possible to send Newsletters and mass mailings via the MPmail relays as long as the messages do not contain any harmful content or spam. There are some guidelines that need to be met, that will prevent the relays to become listed on a deny list, which might have an impact on its services and thus affecting all customers.


Manage Protect follows the guidelines provided by the eco Association of the Internet Industry, which is also strongly recommend to all customers. You can find the guidelines here:

Even though the above mentioned are only guidelines, any newsletter sent through the MPmail relays will need to meet the following requirements:

It will need to fulfill the guidelines for Opt-In
It will need to fulfill the guidelines for Opt-Out


An Opt-In should have happened as explained in the eco guidelines.


The newsletter will need to provide the following options to the recipient:

Possibility to unsubscribe via link
The unsubscribe option needs to be clearly visible and easy to access
Unsubscribing needs to be:
Fully or half automatically
Possible from any location and mustn’t require access to a specific device
Possible from a Unique Identifier
Unsubscribe needs to be permanent

Explaining the Unique Identifier: The system will need to be able to automatically identify the email address belonging to the newsletter where the unsubscribe link was used from. The recipient mustn’t need to enter the email address manually. This will prevent the need for the customer to enter any personal information. It will also prevent any possible issues with forwarding or aliases.

Relay Limits

When sending mass mailings, it is mandatory to adhere to these connection restrictions:

  • Max. 20 connections every minute, per relay server. A connection is an individual recipient in an email (ie To's, CC's and BCC's)
  • Per connection: Max. of 10 emails every minute per relay server.

Manage Protect has 2 relay servers operating in Australia.

This translates to a maximum of around 3600 emails per hour.

If the requirements are not met

If the above conditions are not met, Manage Protect reserves the right to temporary block sending via our relays, until the above-mentioned conditions are fully met. Once announced, Manage Protect will allow 4 weeks* for the sender to adjust their newsletter. If the newsletter does not get adjusted during that time frame, then the communication will be blocked.

To avoid any possible issues, it is recommended to use professional newsletter-software, or using a service provider specialized in distributing newsletters, who will meet the above-mentioned guideline.

*If an incorrect newsletter causes any service interruption for the MPmail customers, then this time frame might need to be shortened or the sender gets blocked immediately.
