What is an email deliverability tool?

An email deliverability tool is a dedicated tool designed to provide you with valuable insights and features to ensure that your emails reach the intended inboxes without being marked as spam.

It helps to monitor and optimize your email outreach performance, increasing the likelihood of successful delivery and effective interaction with your prospects.

And that’s not all! These tools have much more to offer than just ensuring that your emails reach your recipient’s primary inboxes.

Let’s discuss more reasons why it is important to use an email deliverability tool.

Why do you need an email deliverability tool?

There are 3 primary reasons to use an email deliverability tool when running a cold email outreach campaign.

Improve sender reputation

Your sender’s reputation is like your online credibility. When you send emails, email service providers (ESPs) evaluate your sender’s reputation to determine if your emails are trustworthy or not.

An email deliverability tool helps you protect and enhance your sender reputation, increasing the likelihood of successful email delivery. It ensures that your messages are delivered to the Primary inbox.

Furthermore, they also help to keep track of important metrics such as bounce rates, spam complaints, and engagement levels. When you closely monitor these metrics, you can identify and resolve any issues that might harm your reputation.

Avoid spam filters

Spam filters keep recipients safe from unwanted and potentially spam/dangerous emails.

Sometimes, even the most carefully-written emails can trigger spam filters and end up in your recipient’s spam folder.

Using an email deliverability tool, you can check your emails’ content, subject lines, and sender details to make sure no spam filters are being triggered.

Inbox placement monitoring

Last but not least, email deliverability tools help to keep a close eye on the placement of your emails.

By monitoring inbox placement rates, you gain valuable insights into how well your emails are performing. In simple words, you can find out if your emails are hitting the mark and reaching the primary inbox or if they’re getting lost in the promotions tab or spam folder.

Based on these insights, you can take corrective measures to improve the effectiveness of your email campaigns.

Best part? – There are literally dozens of email deliverability tools out there that can help you do just that!

To save you time and effort, we’ve already evaluated all the tools in the market and compiled a list of top email deliverability tools you can consider using in 2024.
