Meeting the deliverability challenge

Email deliverability is about sending an email that reaches your subscribers’ inboxes – it is key to running a successful email marketing campaign.

Swift Digital has been working with local, state and federal government departments for over 15 years to create professional employee communications and help them perfect their email deliverability to ensure their emails land in their subscriber’s inboxes every time.

How do you know if your email deliverability is suffering?

High bounce rates mean an unusual amount of emails are not being received. This may be that the email has been erroneously marked as a hard bounce, which then excludes them from future sends and causing a drop in valid email addresses to which you send.

Assuming that your data list is clean, you can compare that email sent with previous email publishing results and check to see if the rate of engagement has dropped significantly.

So, what could be the cause?

There are three key areas we need to focus on when trying to find the root cause of email deliverability failure:

1. The reputation of your sending IP
2. The email deliverability set-up was incorrect or missing
3. Invalid sender – the organization you are sending from does not permit this email from broadcast, or the sender’s email address is malformed

If the above conditions have been checked and satisfied, you’ll need to troubleshoot the issue further and look at the journey of the email.

What are your troubleshooting options?

Each government department or agency in the public sector has its own mail servers, third-party security software and internal IT network configurations; meaning the journey of a public sector email can have a more complex path when it comes to communicating internally.

The diagram below simplifies an email’s journey from the sender to the recipient, showing four typical journeys of broadcasted internal emails:

Journey A is an email that passes the third-party internal and internal email servers’ configuration, allowing it into the organization’s network. It is also accepted by the internal network protocol. The recipient receives the email.

Journey B is an email that passes the third-party internal and internal email servers’ configuration, allowing it into the organization’s network. However, it is marked as suspicious by the internal network protocol. The recipient receives the email, but it comes with a warning or lands in your spam or junk folder. In this case, the internal network configuration is at odds with the third-party and internal email network settings. In this situation, you should notify your network IT manager.

Journey C is an email that did not pass the internal and third-party mail servers. The security configuration finds the incoming email suspicious. In such a case, it will be quarantined in the mail server until it is released. The recipient will receive their emails late as the emails need to be released to them after it passes the quarantine. At this point, the email can be rejected depending on the rules set here. If rejected, it will send a bounce message back to the broadcast email server.

Journey D is an email that was immediately rejected by the internal and third-party mail servers. A bounce message will be returned to the broadcast server. In this case, the recipient will not receive the email.
