Background

When it comes to email deliverability, the sender's reputation is a big deal. Whether you land in the inbox or in spam is determined by the recipient's mailbox provider (Gmail, Outlook, etc.), and the mailbox providers use sender reputation to determine whether you're trustworthy enough to go to the inbox.

Much like a credit score, your sender reputation is a multi-faceted score based on several factors, including your history of positive and negative behaviors reported from multiple sources. And like a credit score, our sender reputation is ever-changing.

What Influences Sender Reputation?
Invalid email addresses given by parent or typed in by club director.

Club director keep sending to an address that has a prior negative result (without taking any action in between).

"Marked as Spam" Rates, are very heavily weighted by email provider since they are such a clear indication, directly from the user that the email is not wanted. User complaints can come from recipients even if they've opted in to hear from and want the offer from aclub.

To enhance deliverability and inbox placement. We need parents and club director to assists in establishing a positive sender reputation and optimizing the effectiveness.

deliver status

A few words about the info that Club Directors can see in the history of an offer, delivered.
That is info we get from our email provider
delivered means that our server was successful in delivering the email to the parent's email provider server.
But the parent's email provider might have decided to move that email into junk/spam.

Note that junk/spam is common but there could be other name depending on the email provider.

Parents

Please use the Opt-in screen for better odds your offer email will arrive in your Inbox.

Club Director

Before sending an offer, ask the parent if they have added the address offers@ntr.vstarvolleyball.com to their safe list or contacts.

If you see delivered in the offer history, please don't keep re-sending to the same address without asking the parent, if they have taken steps for safe list.

Message has been rejected.

When an email is sent to an invalid recipient for the first time, you receive the regular bounce back notification. Additionally, this recipient is added to our suppression database. In the case that you attempt to send an email to the same invalid recipient, our system holds it and prevents delivery for the reason provided: (Hard) - Recipient was internally suppressed. (Suppressed) If you can confirm that the rejected recipients (which got this response) are valid/active email accounts, you can provide them to us and we can remove them from the suppression list.

The message was internally suppressed by reputation service

This occurs to prevent sending emails to risky email addresses, possible spam traps, and misspelled recipients. Our email provider uses a service Reputation Defender, and they have informed us that addresses that bounce with this reason can not be cleared. At this point, ask if the parent have another address they can use.

Message expired

This typically occurs when an email is sent, but the recipient's email server cannot process it due to time constraints or other delivery issues. There could be a message timeout, a recipient server overload, spam filtering/blacklisting, temporary network issue, DNS issue like missing MX record, etc.

Our email provider servers are designed to queue undelivered emails BUT will resend them for some time. When the resending attempt is finished and the email is still undelivered, it will expire in the queue indicating "Message expired", but with no bounce reason since, kind of like a silent block.

variant of address not found

  • The email account that you tried to reach does not exist.
  • Addressee unknown

MX without valid or null records

This means that the recipient domain does not have an MX record set which means that there is no active email service for it.
