    Statistics show that of the three businesses with a website, two live and breathe email marketing as one of the most effective tools of reaching their prospects, leads, clients, and in turn driving sales. But its effectiveness really depends on the quality of your email list. A B2B email list may be the key distinction between successful campaigns and wasted resources—clean and current, accurate and relevant. In this article I will explain why cleaning your email list is important for higher engagement and conversions as well as offering some actionable tips to ensure your list stays in tip top condition.

    Why a clean B2B email list matters

    An email list is foundational to any good email marketing strategy. But even the best curated lists degrade over time for a lot of reasons. However, a regular email list cleaning helps you reach the right audience, which enhances engagement rates and boosts ROI in return.

    Increase opportunities for deliverability

    In fact, one of the top benefits of a clean email list is better deliverability. Bounce rates, spam complaints, inactive accounts — among other considerations — impact your sender reputation in the eyes of email providers. An invalid email that bounces can hurt your reputation that can send your email marketing to spam. It also improves your sender reputation by cleansing data about inactive or incorrect email addresses to make sure your messages reach their targets.

    Increased engagement

    Targeting valid and interested recipients inherently drives your engagement metrics—open rates, click rates, response rates, etc. By having this clean list, you can focus your efforts only in front of prospects who actually are interested in your products/services, therefore increasing the quality of interaction.

    Cost efficiency

    A lot of email marketing platforms will charge you based on how big your list is. So sending emails to those who are not active, or irrelevant wastes resources. Keeping your lists clean saves unnecessary costs and you can focus on high-value prospects.

    Generally work emails are deactivated soon after an employee leaves his or her firm. And if your email list isn’t updated to reflect these changes, you will also run the risk of sending messages to nonexistent addresses, which will increase your bounce rate. Too many bounced emails can harm your sender reputation, which can impact whether or not your emails are reaching active recipients.

    Misrepresentative messaging that leads to loss of opportunities

    Outdated email addresses don’t only impact your deliverability, they can lead to missed opportunities with potential clients! For instance, if a decision-maker moves to a new company, their old work email is no longer valid, and any personalized messaging that was intended for them is completely wasted. However, your list is the perfect place to add contacts in their new roles and/or at new organizations, which gives you the chance to reconnect and possibly even grow new business.

    Crafting upfront strategy

    Proactive list maintenance can minimize the impact of job change. Tactics like alerting your emails for inaccuracies and using services like LinkedIn to follow people as they change jobs can keep your list as accurate and relevant as ever.

    The dangers of a poorly maintained email list.

    Overlooking list hygiene can result in a host of problems affecting not just your campaigns to the key industry people, but also to your business’ reputation.

    Increased bounce rates

    We’ve said before that when emails get sent to outdated or incorrect addresses, they bounce. A high bounce rate wastes not only your resources, but it also gives a message to your email providers that your list is not reliable and they will start to deprioritize your emails.

    Spam complaints

    Disengaged or uninterested recipients can flag your emails as junk mail, which will further hurt your sender’s reputation. Which can eventually lead to your messages being blocked by email providers and in turn preventing you from reaching even the valid ones.

    Poorly tailored personalization

    Email marketing is one of the most efficient B2B marketing options, because of its ability with regards to personalized messaging. An impure list ruins your personalization efforts, as outdated or inaccurate data can complicate any attempt at tailoring content to the preferences of your audiences. Because poorly targeted emails are less relevant to them, engagement rates drop.

    A guide to keeping a clean B2B email list

    Cleaning your B2B email list is not a one-time effort, it is an ever-going process that requires a combination of strategies and tools. Here’s how to keep your list accurate and effective.

    The use of double opt-in

    A double opt-in process means only truly interested recipients subscribe to your list. This alone prevents fake or incorrect email addresses from slipping through, and therefore helps improve lead quality.

    Segment your list

    This is where segmentation comes in, as you build and refine your email list, segment it based on factors such as industry, company size, job role, etc, which will allow you to send much more relevant content. Explore the segments again and keep up to date on them to make sure your messages are meeting the changing needs of your audience.

    Keep track of the engagement metrics

    Monitor your engagement metrics, such as open rates and click-through rates, to spot inactive subscribers. This will help you figure out if these contacts should stay on your list or not. You can also try to implement a re-engagement campaign for leads that have been inactive for a longer period of time, If they still don’t respond, it’s time to ditch them.

    How do you keep your list clean?

    Email list cleaning and maintenance has never been easier. Here are some tools you can use to help you to make you more efficient and effective.

    Email validation services

    Email verification services to consider include ZeroBounce, NeverBounce and BriteVerify — they will help clean your email list by flagging invalid or risky addresses prior to launching your campaigns.

    CRM integration
