Why are my emails not delivered?

When you have sent an email you can see how it has gone under "Results". Read more below about what delivered, clicked and bounced emails really mean and how you can improve the delivery of your emails.

How to improve email deliveries.

The meaning of "Sent emails".

Number of emails sent is the number you actually chose to email. This also includes contacts that bounce or turn out to be invalid. In short, it is the target group you selected under “To” before pressing Send.

The meaning of "Delivered emails".

This is the number of emails delivered to the recipient’s email server. This does not mean that everyone has opened or even received those emails in their inbox, but only that the recipient’s server has received the email.

What happens to the email is then decided by the recipient’s email server and email client (For example Outlook, Apple Mail or Gmail). Some emails are blocked by the server but most reach the email client who then sorts the email into the correct inbox.

Things that can affect the delivery are the content of your email including links, the reputation of the domain and email address and how other recipients responded to the same email.

The meaning of "Opened emails".

These are the number of emails opened by the recipient. The global average for all email services is about 15-25% opening frequency but can vary quite a bit depending on the content of your emails, who the recipients are and how many you send to at a time.

Some email clients block the tracking of opened emails, which is why this figure is often lower than the actual number of opened emails.

TIP: Try different subject lines or send at other times to increase your opening frequency. How up to date your contact lists are also matters for the opening frequency.

The meaning of "Clicked emails".

Number of all recipients who received the newsletter who clicked on a link in it. The global average for all email services is about 2.5% clickthrough rate but can vary quite a bit depending on the content of your mailing, who the recipients are and how many you send to at a time.

TIP: Try working on clearer prompts, links, and buttons in your mailing to increase your clickthrough rate. Think about what the benefits of clicking on a link is for the recipient. Try working with an offer.

The meaning of "Bounced emails".

Delayed emails are due to either a temporary or permanent problem in delivering the email to the recipient. This may be because the email address no longer exists or is incorrect, the recipient’s mailbox is full, the email server is down, or the email server receiving the email has strict spam rules that prevent the email from being received.

If it is a temporary problem, we usually try again a number of times, so the bounces that are shown are usually due to more permanent problems. Global average for all email services is about 0.5% bounces for larger sendouts but can be much higher if your contact list is old or you have purchased a list of contacts who have not chosen to receive emails from you.

Good luck with your emails and let us know if you run into any problems!
