Finding the right email validation service means getting the best value and features for the money. There's plenty to compare, and here we take a look at ZeroBounce vs. Clearout.
We did our best to make an unbiased assessment using the information Clearout made public.
ZeroBounce and Clearout are both advanced email verification and email-finding tools that can successfully identify the following email types:
These types of contacts are a risk to your sender reputation and can cause serious deliverability issues. It's best to part with them when an email verifier catches them in your database.
Also, both ZeroBounce and Clearout offer bulk verification and an API. An email verification API checks your email signups in real time so you can keep bad data off of your list.
Several aspects set ZeroBounce and Clearout apart.
For starters, Clearout does not mention anything on its platform regarding abuse emails – addresses belonging to habitual complainers.
ZeroBounce, on the other hand, has a solid track record in detecting these risky emails and helping you remove them from your list. It's an extra step to protect your sender reputation and boost your inbox placement.
Most importantly, ZeroBounce effectively evaluates more than 30 types of email statuses and sub-statuses with 99.6% guaranteed accuracy. Clearout offers a similar guarantee with 98% accuracy, making both email verifiers relatively close by comparison.
Clearout offers customer support via live chat and phone on their main websites and via the app. This makes it easy for users to reach out for support. Their estimated wait time is clearly stated at the top of the chat box.
Alternatively, they can provide you with an international phone number to call. You also have the option to leave your phone number and await a call from support when available.
Customer support is powerful for both companies, being available to users 24/7. If you ever have any issues with the email validation or any other tools on the platform, you can find a friendly face willing to extend a hand.
Like ZeroBounce, Clearout is able to provide email verification services (manually, through bulk file upload, and via API). One thing that differentiates Clearout from ZeroBounce is their ability to validate phone numbers.
Both companies offer an Email Finder service, which allows you to look up potential email address patterns to make new email connections. Clearout also has a new AI-based prospecting service that promises to provide further context and data points for every lead.
ZeroBounce offers its own list optimization and email deliverability tools. Here's what the company offers by comparison:
Clearout and ZeroBounce offer all their respective additional features through their platform for a more user-friendly experience.
