Bulk Email Verification: Tips & Tools [2024]

Business is all about communicating with customers, and email marketing remains one of the most powerful online tools in this field. Yet, you shouldn’t relax after you launch your email campaign. Task #1 here is to ensure you actually reach your recipients. So, hitting the “Send” button is simply not enough. You can start writing your success story after you reach your audience. 

That’s the moment for bulk email verification to come on stage, which is different from bulk email validation. This procedure is essential for email marketing. Handling it properly, you can improve your email deliverability and protect your sender reputation. In this case, you will not ruin your campaign by sending your precious messages to invalid or inactive email addresses. In this guide, you will learn about the importance of bulk email verification and how it works. You will also know what services exist that fit your needs in this area. Now, let’s dive into it! 

What Is Bulk Email Verification?

Bulk email verification is a process that checks your contacts’ email addresses for validity and deliverability. The purpose is to ensure that the emails on your list are not just correct and active but capable of receiving your messages. The bulk email verifier tool will identify “bad” emails and flag or remove them from your list.

How does it work? You run your email contacts through an algorithm that tests each address for common errors. The range of these errors could be from simple typos to inactive domains to even spam traps. In the end, this verification process ensures that your list consists only of high-quality, valid email addresses. You can gain a lot from it, from preventing hard bounces to maintaining a good sender reputation and improving overall email deliverability. In the next section, we will explain it in detail. 

Why Is Bulk Email Verification Important?

You can be an experienced marketing fighter or a new kid in town to email campaigns, yet the health of your contacts list is crucial to your success. Let’s look at key reasons why bulk email verification is essential for your marketing success.

Improves email deliverability

The biggest challenge for an email marketer is probably getting their messages into their recipients’ inboxes. If you don’t make it because of invalid or inactive email addresses in your list, you can face real problems. Email service providers (ESPs) may consider your emails low-quality or spam. This way, you can damage your sender’s reputation and become, in the worst-case scenario, a spammer in their eyes. Bulk email verification would help you avoid such an outcome by ensuring you send your letters to valid addresses.

Protects sender reputation

As mentioned above, a good sender score is the cornerstone of your reputation as an email marketer. It is also crucial for maintaining high deliverability rates, an important indicator. If your emails frequently bounce or receive negative feedback, ESPs may flag your domain or IP address. This way, you ultimately end up not reaching your audience and ruining your email marketing campaigns. You must regularly verify your email list to ensure you’re targeting active users. This is how you make it go around: your bulk email verification helps you reach the audience, and that, in turn, helps build a solid sender reputation.

Reduces costs

You don’t want to waste your money, do you? Typically, email marketing platforms charge depending on the number of emails sent. If you have plenty of inactive addresses, your list will be inflated with “bad” emails. When you remove invalid or risky addresses thanks to bulk email verification, you will reduce, or “deflate,” your email contacts list. As a result, you can save money because you won’t have to send your messages to non-existent recipients. Only the right people would see your messages.

Prevents hard bounces and spam traps

Hard bounces can damage your sender score. You can “achieve” it by sending emails to invalid addresses. The worst thing is to get into a spam trap, an email address set up specifically to catch spammers. If you hit one of these, it can severely impact your email deliverability. You may not worry about it with bulk email verification. The process will indemnify and remove these spam traps from your list.

How Does Bulk Email Verification Work?

Let’s now check out the bulk email verification process step-by-step.

1. Syntax check

The first step is the most “primitive,” yet essential. It is about checking the email address format. Syntax check ensures that all addresses follow the standard format, which is “name@domain.com,” and flags any that contain typos or formatting errors.

2. Domain verification

The next step is to check the domain, the part after the “@” symbol. It ensures that the email is valid and active, which means it has a mail server, known as an MX record, capable of receiving emails.

3. Email ping

We’re almost done! This step involves an email ping, which is like a reconnaissance operation. The verification tool sends a message to the recipient’s mail server without actually delivering an email. As a result, the tool confirms that the email address is valid and the mailbox exists.

4. More checks

There can also be some extra checks. For example, verification tools may perform additional checks to identify disposable email addresses, role-based emails (e.g., “support@domain.com”), and spam traps.

When Should You Use Bulk Email Verification?

Now, let’s see when you should—or even must—consider using bulk email verification in your email marketing strategy.

1. When you launch a big campaign

Always verify your email list before launching a large email marketing campaign. This will ensure your messages get to your target audience and that you don’t experience bounces and spam complaints.

2. You acquired a new list

Did you recently acquire a new email list? If you did, run it through a verification tool; it’s like checking software for viruses.

3. Regular list maintenance

If you have a car, you must check your oil level regularly. The same thing is with your email list. Even if it is organic, it’s essential to check it regularly. Over time, recipients change email addresses, unsubscribe, or stop engaging with your messages. Regular email verification keeps your list healthy!

How to Choose the Right Bulk Email Verification Tool

There are plenty of bulk email verification tools on the market. Probably, looking for a free bulk email verifier is a good idea. But if you’re running complicated email marketing campaigns, you should be looking for professionals in the field. So, the question is: how do I choose the right service? We recommend you consider the following factors: 

Accuracy

Accuracy, by any means, is the most important feature of any email verification tool. Your task is to find a service that can correctly detect invalid email addresses. The subtask is to minimize false positives. Check out reviews and testimonials to see how reliable the tool is.

Speed

Speed matters in the contemporary world, especially if you’re working with an extensive email list. Some services offer faster processing times than others. Choose the tool that can handle the size of your list without delays.

Integration options

Often, email verification tools offer integrations with popular email marketing platforms like Mailchimp, Constant Contact, and HubSpot. As a marketer, you should already know these names. So, choosing a verification tool that integrates seamlessly would be a great idea.

Pricing policy 

Pricing models can vary. Some services charge per verified email address, while others may offer subscription plans. Choosing a pricing model that fits your budget is completely up to you.

Reliable customer support

Sometimes, all you need is customer support. Access to responsive customer support can make a difference. If you run a big marketing campaign, you will face challenges sooner or later. That said, a service with decent customer support is essential. The best thing would be a customer support team that uses both email and chat. The email channel is good for extensive issues. The chat channel is great when you need instant advice on the go.

FAQs

Can email verification prevent all bounces?

• Well, no. It won’t get a 100% prevention rate, but it can significantly reduce the number of bounces. Some email addresses in your list may appear valid during verification but still bounce if, for instance, the recipient’s mailbox is full.

How often should I verify my email list?

• We advise you to verify your email list regularly. If you run campaigns frequently, this recommendation becomes a must. A good idea would be to verify your list every three to six months.

Can I verify the purchased email lists?

• You can do it anytime, technically. However, we don’t recommend it. Such online shopping may bring your email lists containing many invalid addresses, spam traps, and other junk. There is no need to say that it can harm your sender score. The best thing is to have a natural email list.
