What Is Deliverability?

Deliverability is crucial to relay messages to your subscribers. According to Stastica, 48.16 percent of all global emails are marked as junk. Spam filters are vigilant about marking spam emails. If your emails are being marked as spam, they won’t be read by your customers.

There is a difference between the delivered rate and deliverability. The delivered rate measures the number of emails that don’t receive a hard or soft bounce. It does not measure where the emails land.

Emails can have a 99% delivered rate. This means that 99% of the total emails did not bounce. However, some of those emails could be delivered to the spam folder. This means that they won’t even be seen.

While the delivered rate is important, do not assume that it will translate to inbox placement rate. It just means that it wasn’t rejected.

When it comes to deliverability, there are many factors that come into play. It will rely on your content, list quality, subscriber engagement, authentication and infrastructure, and spam filters.

Selecting the right email autoresponder can help to improve deliverability. This will increase the likelihood that your customers can read your emails.
