If your application is going to be sending out single messages (or less than 25 messages at a time), we highly suggest using SMTP. SMTP is a better option for sending out small amounts of mail. If you have questions on configuring your application to use SMTP, please visit with a member of our support team.
On the other hand, you may need to use our mail relays if your application will be sending out messages to a larger mailing list. If that’s the case, please review the following rules for sending messages through our mail relays:
- Your message must have a working unsubscribe link, which must be demonstrated to us upon request.
- The message must have a valid Return Path. This means the message must have a valid from address listed in the message.
- The message of the email can only refer to the domain the message is being sent from. This means “DomainA.com” cannot send messages for “DomainB.com.”
- You must obtain TUBhost's advance approval for any bulk or commercial e-mail, which will not be given unless you are able to demonstrate, at a minimum, that your intended recipients have given their consent to receive e-mail via some affirmative means, such as an opt-in procedure, your procedures for soliciting consent include reasonable means to ensure that the person giving consent is the owner of the e-mail address for which the consent is given, you retain evidence of the recipient's consent in a form that may be promptly produced on request, and you honor the recipient's and TUBhost's requests to produce consent evidence within 72 hours of receipt of the request.
- We do not allow bulk or commercial e-mail being sent to more than five-thousand (5,000) users per day at a rate of 250 messages every 20 minutes.
- TUBhost may test and otherwise monitor your compliance with its requirements, including requesting opt-in information from a random sample of your list at any time.
