On top of your worries about creating email content that converts, you need to make sure the addresses you’re sending to are legitimate and real.

This is where a business email verifier comes in: a tool that makes sure you’re reaching out to real people.

It’s all about keeping those communications crisp, clear, and actually reaching your audience.

In this article, we’ll cover some of the best tools available in 2024.

So, let’s dive in and see what each of these top email verifiers brings to the table.

Top business email verifier features to look out for

But first, we’ll see what to look out for in the best business email verifier so it can really help you get better results.

Spam trap identification

A spam trap is an address deliberately set up by domains to catch spammers. If you send an email to one of these, your message is automatically flagged as spam.

Hitting spam traps can severely damage your sender’s reputation – a score issued by internet service providers.

High accuracy

High accuracy means that the verifier can confidently determine which addresses are legitimate and not. For example, Bouncer has 99.5%+ accuracy, which means that only a small percentage of emails slip by our detectors.

A low number of unfamiliar results

Unfamiliar results are those that the verifier tool does not know where to put. In other words, it can’t tell if they are legitimate or not. A good tool will have a very low number of unfamiliar results.

High speed of verification

A fast verification process means you can move more swiftly from planning to execution, without being bogged down waiting for your list to get cleaned up. For example, Bouncer verifies 200,000 emails per hour per customer.

SOC2 compliance

SOC2 compliance is not just nice to have. It assures you that the verifier adheres to high standards of security and privacy and protect your and customers data.

Flexible pricing

Great verifier tools give you a variety of payment options. This includes both monthly and per-email pricing models.
