You built it and everything looks fresh and clean. But time goes by, things have worn out, the walls get a little dirty, and if you don&#8217;t take care of it, your house becomes hard to use and in time maybe even completely unusable.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s the same with your B2B email database &#8211; building your list is just the first phase.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">See why your prospect list needs a regular cleanup and what are the best practices to do so.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">What is prospect list hygiene?\u00a0<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">\u201cThe larger the number involved, the better the occasion\u201d doesn\u2019t fit cold emailing. In fact, smaller prospect lists with well targeted, narrowed criteria are more valuable than a larger list of potential customers who are not interested in your solution.<\/span><\/p>\n<p>Prospect list hygiene means maintaining accurate and up-to-date information in your B2B database.<\/p>\n<p>It helps you avoid having your emails marked as spam and definitely improves three key email metrics: deliverability, open rates and click rates\u2014and it ensures you consistently <a href=\"https:\/\/tldv.io\/blog\/data-cleansing-tools\/\">deliver emails to inbox<\/a>.<\/p>\n<h3><span style=\"font-weight: 400;\">\u201cDirty\u201d prospects list means:\u00a0<\/span><b><\/b><\/h3>\n<ul>\n<li aria-level=\"1\"><b>Outdated information<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Your list may contain email addresses that either don\u2019t exist anymore or have no employee associated with them. If you try to keep sending your emails to these addresses, they will bounce back and affect your deliverability.<\/span><b><\/b><\/p>\n<p>Also, email accounts that have been inactive for some time might get turned into <a href=\"https:\/\/woodpecker.co\/blog\/what-are-spam-traps-how-to-avoid-them\/\">spam traps<\/a> and harm your reputation if you send to those addresses.<\/p>\n<ul>\n<li aria-level=\"1\"><b>Inaccurate data<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Some of the email addresses you have on your list may be misspelled, a piece of data might be entered in the wrong field, or a contact might be duplicated. Messy data is not only disturbing your workflow, but also the results you get.<\/span><b><\/b><\/p>\n<ul>\n<li aria-level=\"1\"><b>Outdated targets<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">If you want to improve your business results, it\u2019s normal to shift your directions and pivot your targets. In this scenario, if your old prospect list doesn&#8217;t correlate with your new offering, you&#8217;ll be contacting leads who may not be interested in your services.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">How often should you clean your prospect list?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">If you\u2019re wondering when is the right time for cleaning up your prospect list, you should first take a look at your stats.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The general rule says that you should clean your email list at least once every six months, but if you notice your numbers starting to drop, update your list as soon as possible.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you\u2019re adding prospects to the list daily, you should do it as often as every month.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">How do you create a high-quality prospect list?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">To maintain good-quality data, you need to have it in the first place.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Like we\u2019ve said in the past (and we continue to say), we do not recommend buying <\/span><a href=\"https:\/\/woodpecker.co\/blog\/outbound-prospect-list\/\"><span style=\"font-weight: 400;\">ready-made lists<\/span><\/a><span style=\"font-weight: 400;\">. It might sound like an easy option, but the contacts on such lists can be outdated.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Imagine buying a list of 1000 email addresses and finding out half of them don&#8217;t even exist. You\u2019ll only burn money. Not to mention people on such a list probably got loads of emails already, so you risk annoying them and having your emails marked as spam.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Instead, do it <\/span><a href=\"https:\/\/woodpecker.co\/blog\/outbound-prospect-list\/#way--build-it-yourself\"><span style=\"font-weight: 400;\">manually<\/span><\/a><span style=\"font-weight: 400;\"> or order it from a company who offers list building.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">What to focus on while building a prospect list?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">When choosing the right criteria, I suggest doing a &#8220;reverse search&#8221;. Pick a few companies you work for and scan them using prospecting tools. Find out:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Which industries do they operate in?<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">What is their size?

Here\u2019s what he pointed out as best practices:<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">1. Always validate email addresses<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Before sending out an email campaign and every time you clean up your prospect list, you should validate your email addresses.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">That\u2019s why Woodpecker is natively integrated with the best email validation tool &#8211; <\/span><a href=\"https:\/\/woodpecker.co\/blog\/bouncer-integration\/\"><span style=\"font-weight: 400;\">Bouncer<\/span><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p>\n<aside class=\"cta-block cta-block--a-version js-cta-block ab-no-10-cta-block ab-no-11-cta-block\">\n  <p class=\"cta-block__heading u-heading-preset-md-600\">Send emails that get delivered<\/p>\n  <div class=\"cta-block__form-container\">\n    <form class=\"js-cta-block-form\" action=\"https:\/\/woodpecker.co\/signup\/\" class=\"cta-block__button-only-form js-cta-block-no-input-form\">\n      \n\n\n\n\n\n\n\n\n<button class=\"c-button js-button c-button--color-main c-button--size-small u-focus-visible-outline\">\nStart free trial\n<\/button>    <\/form>\n    \n    <form class=\"c-input-button-form js-cta-block-form cta-block__form\" action=\"https:\/\/woodpecker.co\/signup\/\" method=\"POST\" novalidate>\n        \n  <div class=\"c-form-field js-form-field  c-input-button-form__form-field\">\n    \n    <label class=\"c-label c-form-field__label\" for=\"cta-block-form-email-1597724308\">Work email<\/label>\n\n                    \n  <input class=\"c-input  js-input c-input-button-form__input\" placeholder=\"will@woodpecker.co\" name=\"email\" id=\"cta-block-form-email-1597724308\" type=\"email\" \/>\n            \n    <span class=\"c-form-field__error js-error\">\n                                      Invalid email format\n        \n\n                <\/span>\n  <\/div>\n\n        <div class=\"c-input-button-form__button\">\n          \n\n\n\n\n\n\n\n\n<button class=\"cta-block__button c-button js-button c-button--color-main c-button--size-small u-focus-visible-outline\">\n                Start free trial\n        \n\n<\/button>        <\/div>\n\n            <\/form>\n  <\/div>\n<\/aside><\/p>\n<p><span style=\"font-weight: 400;\">Bouncer verifies and validates each email address from your list right before an email is sent to it, and displays invalid addresses in your stats. Woodpecker won&#8217;t send emails to those that are invalid, so you keep your domain reputation intact and deliverability at a very high level.<\/span><\/p>\n<img decoding=\"async\" loading=\"lazy\" class=\"aligncenter wp-image-12674\" src=\"https:\/\/woodpecker.co\/blog\/app\/uploads\/2021\/06\/Zrzut-ekranu-2021-06-24-o-11.49.24-300x160.png\" alt=\"Woodpecker campaign invalid emails\" width=\"740\" height=\"395\" srcset=\"https:\/\/woodpecker.co\/blog\/app\/uploads\/2021\/06\/Zrzut-ekranu-2021-06-24-o-11.49.24-300x160.png 300w, https:\/\/woodpecker.co\/blog\/app\/uploads\/2021\/06\/Zrzut-ekranu-2021-06-24-o-11.49.24-1024x547.png 1024w, https:\/\/woodpecker.co\/blog\/app\/uploads\/2021\/06\/Zrzut-ekranu-2021-06-24-o-11.49.24-768x410.png 768w, https:\/\/woodpecker.co\/blog\/app\/uploads\/2021\/06\/Zrzut-ekranu-2021-06-24-o-11.49.24.png 1226w\" sizes=\"(max-width: 740px) 100vw, 740px\" \/>\n<p><span style=\"font-weight: 400;\">You can also use tools like <\/span><a href=\"https:\/\/www.ipqualityscore.com\/\"><span style=\"font-weight: 400;\">IPQS<\/span><\/a><span style=\"font-weight: 400;\"> or <\/span><a href=\"https:\/\/mailtester.com\/en\/\"><span style=\"font-weight: 400;\">MailTester<\/span><\/a><span style=\"font-weight: 400;\"> to do this. Just upload your email list and the solution will run a validation to tell you which email addresses your message will bounce back to. This way you can remove invalid addresses and make sure you don&#8217;t send your campaigns to non-existent addresses and get bounces.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">2. Find individuals and companies that match your Ideal Customer Profile (ICP)<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">It may seem obvious to only contact people who are a potential fit for your business, but some people buy ready-made B2B email databases without questioning whether they actually fit their ideal criteria.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you want to get good results and not waste your time making ineffective demo calls later, you need to build your lists according to your\u00a0 <\/span><a href=\"https:\/\/woodpecker.co\/blog\/ideal-customer\/\"><span style=\"font-weight: 400;\">Ideal Customer Profile<\/span><\/a><span style=\"font-weight: 400;\">. Even if you get a lot of responses, you&#8217;ll find that these prospects either don&#8217;t have the budget for your solution, aren&#8217;t the decision maker, or don&#8217;t need your product or services at all.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">3. Group your targets<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Perhaps you offer many different products or change your <\/span><a href=\"https:\/\/woodpecker.co\/blog\/value-proposition-how-to-tell-my-addressee-what-i-want-from-them\/\"><span style=\"font-weight: 400;\">value proposition<\/span><\/a><span style=\"font-weight: 400;\"> from time to time. In this case, you need to make sure that the people you are targeting via cold email campaigns might actually be interested in your current offering.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you want to show that your product can increase revenue or employee satisfaction, it&#8217;s worth targeting mostly CEOs or sales directors. If you want to talk about minimizing waste or improving processes &#8211; your campaign could target operations managers or digital leaders. As well as grouping your prospect lists by job title or department, you could also divide them by specific location, industry or technology.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The more narrowly you can target your prospect list, the more you can <\/span><a href=\"https:\/\/woodpecker.co\/blog\/personalization-deliverability\/\"><span style=\"font-weight: 400;\">personalize your email campaigns<\/span><\/a><span style=\"font-weight: 400;\"> and significantly increase your response rate.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">4. Delete inactive contacts<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If you\u2019ve already sent several messages to a prospect but they haven\u2019t opened any of them, it might be better to get rid of such contacts. So to clean up your prospect list, delete those prospects who don&#8217;t engage and ignore your messages. This way, you&#8217;ll not only improve your rates, but you&#8217;ll also ensure that you&#8217;re not constantly sending unwanted emails.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">5. Monitor your bounce rate<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Generally, a bounce rate of 2% or less is acceptable and considered a good result. So if you send emails to 1000 prospects and get 20 bounces or less, you&#8217;re good. But if your bounce rate is above 2%, then you need to take some action to improve it.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Want to see why emails bounce? Go to <\/span><a href=\"https:\/\/woodpecker.co\/blog\/why-emails-bounce-10-most-common-issues\/\"><span style=\"font-weight: 400;\">this blog post<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">6. Engage with prospects to warm them up before outreach<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Your prospects are more likely to open an email and reply if they saw your photo or your name someplace before. So, if you want to increase your open and response rates, incorporate some <\/span><a href=\"https:\/\/woodpecker.co\/blog\/warm-prospects\/#whats-in-it-for-you\"><span style=\"font-weight: 400;\">additional activities<\/span><\/a><span style=\"font-weight: 400;\"> in your outreach: you can follow your prospects on Twitter, send them a <\/span><a href=\"https:\/\/woodpecker.co\/blog\/personalize-linkedin-connection-request\/\"><span style=\"font-weight: 400;\">personalized connection request on Linkedin<\/span><\/a><span style=\"font-weight: 400;\">, comment on their blog posts or display to them retargeting ads. These actions, if done and orchestrated correctly, can really boost your results.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Why all this effort?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Applying prospect list hygiene can be time-consuming and requires some extra effort, but it is critical to achieving positive results. Even the best cold email campaign will not be successful without an accurate list of prospects. It also works hand in hand with <a href=\"http:\/\/www.bookyourdata.com\/blog\/email-warm-up-tools\">domain warming for email<\/a>, which gradually builds trust with email providers and helps you land in the inbox\u2014not the spam folder.<\/span><\/p>\n<p>\n<aside class=\"cta-block cta-block--a-version js-cta-block ab-no-10-cta-block ab-no-11-cta-block\">\n  <p class=\"cta-block__heading u-heading-preset-md-600\">Send emails that get delivered<\/p>\n  <div class=\"cta-block__form-container\">\n    <form class=\"js-cta-block-form\" action=\"https:\/\/woodpecker.co\/signup\/\" class=\"cta-block__button-only-form js-cta-block-no-input-form\">\n      \n\n\n\n\n\n\n\n\n<button class=\"c-button js-button c-button--color-main c-button--size-small u-focus-visible-outline\">\nStart free trial\n<\/button>    <\/form>\n    \n    <form class=\"c-input-button-form js-cta-block-form cta-block__form\" action=\"https:\/\/woodpecker.co\/signup\/\" method=\"POST\" novalidate>\n        \n  <div class=\"c-form-field js-form-field  c-input-button-form__form-field\">\n    \n    <label class=\"c-label c-form-field__label\" for=\"cta-block-form-email-312991048\">Work email<\/label>\n\n                    \n  <input class=\"c-input  js-input c-input-button-form__input\" placeholder=\"will@woodpecker.co\" name=\"email\" id=\"cta-block-form-email-312991048\" type=\"email\" \/>\n            \n    <span class=\"c-form-field__error js-error\">\n                                      Invalid email format\n        \n\n                <\/span>\n  <\/div>\n\n        <div class=\"c-input-button-form__button\">\n          \n\n\n\n\n\n\n\n\n<button class=\"cta-block__button c-button js-button c-button--color-main c-button--size-small u-focus-visible-outline\">\n                Start free trial\n        \n\n<\/button>        <\/div>\n\n            <\/form>\n  <\/div>\n<\/aside><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Prospect list hygiene is like maintaining your own house.
