Email Delivery Rate
Email deliverability measures the number of emails that arrive in your subscriber's inbox compared with the total number of emails sent.
It is important to understand and measure email deliverability. If your email deliverability rate is poor, then this means you are sending campaigns which are not being recieved, which ultimately will lower your email ROI.
Many factors can impact your email deliverability. This includes your sender reputation, which can be based on the content of your subject lines along with the volume of emails you send in a certain timeframe.
Other factors also exist, which is why it’s important to read up on email best practices, especially if you want to fix a poor deliverability rate or maintain an existing good rate.
Example
Imagine you send 500 emails to your subscribers as part of an email campaign.
For whatever reason, let’s say 10 of those emails bounce, meaning only 490 emails were actually sent.
Based on the above formula, this would give you an email deliverability rate of 98%.
In general, an email deliverability rate of 95% and above is considered a good rate to aim for.
Low email deliverability rates can result in damage to your sender reputation, meaning your emails may automatically be filtered as spam.
