What are the tools to use to test the deliverability of your emails?

What is email deliverability?

A quick reminder: email deliverability refers to the ability of an email to reach its destination and to be correctly displayed to the recipient.

This includes the email's ability to avoid spam filters and email blockers. Not to mention also, the ability of the email to display clearly on different devices and email applications. 

To conclude, deliverability is a key factor for the success of email campaigns and the reputation of an email sender.

How to measure your deliverability rate?

The deliverability rate is usually calculated by dividing the number of successfully delivered emails by the total number of emails sent. This rate gives an idea of the performance of the email sender in delivering messages to its recipients.

Kiliba shares the formula that allows you to calculate your deliverability rate:

• (Number of emails delivered / Total number of emails sent) x 100

You may also note that the deliverability rate may vary depending on the different email providers and filtering differences. Therefore, you should constantly check your deliverability rate to ensure that your email campaigns continue to successfully reach your prospects.
