ZeroBounce Review: Best Email List Scrubbing Service?

Email marketing is one of the best ways to promote your business. A lot of marketers still haven’t made the most of its potential, but, believe me, email marketing can boost up your business if used wisely. The key to email marketing success is sending campaigns to valid email addresses. Thus, it is extremely important to build a healthy email list and periodically use an email list scrubbing service to maintain your email hygiene.

Invalid email addresses can end up on your list anytime, and it’s not your fault. They can be due to typos your subscribers make while trying to register on your mailing list. At times, people misspell their address, especially when they’re using their phones, and that results in an incorrect lead.

Then, there are abandoned email addresses that represent little value to your email marketing goals. People change their jobs or simply decide to switch to a different email service, and they abandon their old email addresses. A dormant lead is a lead that doesn’t serve your purposes. Furthermore, there are spam traps, disposable, catch-all and abuse email addresses that are a risk to your sending reputation and it’s best to remove them from your list.

If you’re asking yourself how I have good news for you: there are email list scrubbing services that can solve these issues for you very quickly. One of them is ZeroBounce. This post will walk you through a detailed review of ZeroBounce and the services they provide.

For an email list scrubbing system to be performant, there are lots of features it should provide. Let us have a look at the features offered by ZeroBounce.

#1 Email Bounce Detection

If you use email to promote your business, email deliverability is essential. You want your campaigns to reach your audience, and if your bounce rates are high, that means many of your subscribers are not receiving your emails. ZeroBounce can tell which emails are going to bounce and it isolates them from your email list.

#2 Email Abuse and Spam Trap Detection

Abuse emails belong to people that have a habit of marking emails as Spam. This tarnishes your sending reputation and, in the long run, causes poor email deliverability. ZeroBounce removes abuse emails from your list and helps you maintain your reputation.

Spam traps have absolutely no value, as they don’t belong to real people. They are created only to lure in spammers and block them. ZeroBounce removes spam traps, thereby supporting your effort to reach more people, not bots.

The system also offers Toxic Domain Detection. This tool determines spam, abusive, invalid and bot-created emails.

ZeroBounce’s email list scrubbing system detects disposable email addresses, also known as “temporary.” Their potential is very poor because no one creates a disposable email to use it in the long run.

ZeroBounce comes with an application program interface (API). You can hook the application on your site to validate new email addresses automatically, in real-time. The API prevents bad email addresses to sign up on your list and is a crucial tool for those concerned with email hygiene.

The system is highly effective in validating catch-all emails and providing complex insight into their activity levels.
