Why use a deliverability booster and monitoring tool?

Here's why you need to use a deliverability booster and monitoring tool:



Think of email deliverability as a shield for your emails. It makes sure your emails get delivered and reach the right people in their inboxes. When you work on your deliverability, email service providers (ESPs) will trust you and are less likely to land your emails in the spam folder.



In the long run, monitoring your deliverability is the only way to follow closely your campaigns performance. You’ll receive insights on your technical setup, email content, sending habits and overall performance and know how to improve every part of your campaign.

Does deliverability really have an impact on email performance?

Email deliverability is the process that will make your emails land in your leads inboxes. 



If you’re emails land in the spam folder, they will be ignored and you won’t generate revenue.
