Why Bulk Email Verification and List Cleaning Matters

Why Bulk Email Verification and List Cleaning Matters

Today’s B2B marketers are faced with many challenges, and one of them is managing their company’s digital reputation. This includes maintaining a healthy sender reputation in the eyes of internet service providers (ISPs) to keep email deliverability rates high. Spam traps, complaints, high bounce rates, and a whole host of other nasty surprises can all impact your sender reputation.

Email marketing is still considered to be one of the most cost-effective and quickest ways of reaching a targeted audience, but the quality of your mailing list is more important than its size. To keep your sender reputation, deliverability rate, open rate and conversion rates at a healthy and sustainable level, do yourself a favor and use a bulk email verification service before sending that large campaign.

What Does Bulk Email Verification Mean?

Companies use a bulk email list verification service when they need to send an email campaign to a list of cold contacts. The main goal of the verification process is to remove emails that will bounce back on a given email marketing campaign, or otherwise aren’t suitable to send to.

A bulk email verification service will analyze each of the email addresses on the list by running it through a number of validation checks. The process of “list cleaning” confirms the legitimacy of the contact records by omitting email addresses the service deems to be invalid. The standard rate of verification accuracy among the many services available is 97% or above.

All list verification services aim to produce a healthy, active list of real email addresses, but no two proprietary algorithms are the same. If the validation process is completely successful, all bad email addresses should be filtered out. With spam traps and invalid addresses removed, the performance of your email marketing campaign will jump, because you won’t waste time sending messages to contacts that don’t exist. More importantly, you can avoid damaging your sending reputation.

How a Bulk Email Verification Service Works:

The goal is to remove the email addresses that could potentially waste your time (and budget), and negatively impact the overall deliverability of your campaign. If you don’t run your contact list through a verification service, chances are your campaign will not reach its full potential.

The simplest of bulk email checkers will go through the basic list validation and legitimacy checks listed below. Clickback performs many more hygiene checks than the ones listed below when you upload your lists, and that’s just scratching the surface of how it helps your campaigns succeed. Here is a brief explanation of the typical checks a bulk email verification service performs:

list cleaning

  • Remove Duplicate Emails
  • DNS Record Verification (Invalid Domains)
  • Email Address Syntax (Improper Format)
  • Detect Role-Based Accounts (info@example.com)
  • Detect “Junk Collector” Emails (disposable addresses)
  • Spam / Honeypot Detection (bots, bad emails, spam seeds)
  • SMTP Verification (Ping Mailboxes)

The file you upload will either be .CSV or a large list of email addresses separated by commas, depending on the tool you use. Running this list through an email verifier leaves you with a valid email address list that’s ready to be used.

As you can imagine, the accuracy of a bulk email verifier is the single most important aspect of the tool. It’s a good idea to confirm that the email validation service you use is applying the hygiene checks in real-time, based off of current data records. You’ll also want to choose a tool that can handle a large list of cold contacts. Many of the budget or free email verification services limit your list to a small amount (under 5000 emails!).

Clickback can clean and deliver your campaigns to 150,000 contacts or more, depending on your needs.

Benefits of Email List Verification for B2B Marketing

Now that you know how it works, what concrete benefits does your B2B email marketing get from using a verified list?

Improved Deliverability

Deliverability – namely, how many of your messages are reaching inboxes instead of junk folders – is one of the most important aspects of a successful campaign. If the messages are not reaching the inbox of your prospects, it doesn’t matter how clean your list is. A cold email campaign to a purchased list presents different challenges than an opted-in list, but you can avoid the majority of them by using a good verification service.

Increase Conversion Rates

When you send your campaigns to real, active emails, your campaign’s metrics will be much more accurate, so you can focus on creating and testing better content – not worrying about whether or not your messages are hitting spam traps. It’s a lot easier to work on optimizing your conversion rate when you can be confident you’re sending to real people.

A Better ROI

A purchased list of cold contacts can be a valuable asset to your business, but only if it realizes its true potential. All lists decay over time, so get rid of the invalid emails on the list and focus on the contact records that generate targeted, warm leads for your business.

Maintain a Healthy Sender Reputation

Hitting spam traps, honeypots and bad addresses damages your sender score. Your deliverability plummets, and suddenly the real contacts on your list stop receiving your message. Avoiding these is the chief reason you should use a verification service.

With the right approach, outbound email marketing can be a powerful strategy to generate targeted B2B leads for your business. If you’re thinking about purchasing an email list, or currently own a large list of cold contacts, maximize your ROI by running it through the necessary hygiene checks before sending a campaign.

Verify your List and Send Cold Campaigns from a Single Platform

By now, you should have a good understanding of why B2B marketers rely on bulk email verification and validation tools to get the most out of their cold lists. They remove spam traps, bad emails, and other hidden factors that negatively affect the deliverability of your campaigns, letting you focus on your campaigns instead of worrying about deliverability.
