But I would call it an extreme timeline. You can find various expert recommendations telling you to do email list hygiene once per 6 months, once every 3 months, or even more often.\u00a0\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Overall, it all depends on the size of your list, the regularity of your email campaigns, and, of course, the industry you are running your business in.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For instance, for <\/span><a href=\"https:\/\/snov.io\/glossary\/e-commerce\/\"><span style=\"font-weight: 400;\">e-commerce<\/span><\/a><span style=\"font-weight: 400;\"> companies that send email campaigns to their customers weekly, a healthy routine would be to do email scrubbing once a month.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">I would advise you to stick to 3-month regularity and also recommend analyzing your previous <\/span><span style=\"font-weight: 400;\">email cleansing campaigns.<\/span><span style=\"font-weight: 400;\"> This will help you better understand the ratio of invalid or uninterested contacts against valid addresses and plan your email scrubbing ahead.\u00a0<\/span><\/p>\n<h2 id=\"keep\"><span style=\"font-weight: 400;\">How to keep your email list clean: 8 email hygiene best practices<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Email <\/span><span style=\"font-weight: 400;\">hygiene<\/span><span style=\"font-weight: 400;\"> demands regularity and consistency, so I won\u2019t exaggerate if I say that you need to work out your own email scrubbing strategy to turn the wheel and never stop it. Here are eight best practices to help you clean up your email list effectively:<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">1. Analyze your email list<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">To stick to the email scrubbing routine and schedule your <a href=\"https:\/\/snov.io\/blog\/email-list-cleaning-services\/\">email list cleaning<\/a> campaign, you need to first consider the quality and quantity of your contact data.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Assess whether your email list has duplicates, check for typos, and look at how many contacts stay cold to your messages. By doing such analysis regularly, you\u2019ll understand the percentage of inactive subscribers in your list and plan your email scrubbing accordingly.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">2. Use a double opt-in<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Create the most favorable conditions for filtering your email list through a double <\/span><a href=\"https:\/\/snov.io\/glossary\/opt-in\/\"><span style=\"font-weight: 400;\">opt-in.<\/span><\/a><span style=\"font-weight: 400;\"> A double opt-in presupposes that a user submits their email address to a form on your landing page; then, they receive a confirmation email to prove their subscription.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Double opt-in prevents your emails from being automatically marked as spam, helps break the ice and send your new user a <\/span><a href=\"https:\/\/snov.io\/blog\/welcome-email-template\/\"><span style=\"font-weight: 400;\">welcome email<\/span><\/a><span style=\"font-weight: 400;\">, and, most importantly, saves your email list from contacts who are not eager to read your email messages.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">3. Make it easy to unsubscribe<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">It\u2019s not unusual that some subscribers forget they once opted in to your email list. But it can become a real problem for you as these users might put your emails straight in the spam folder \u2013 which, as you know, is not the best outcome.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s much better if you give them the option to <\/span><a href=\"https:\/\/snov.io\/blog\/email-unsubscribe-rate\/\"><span style=\"font-weight: 400;\">unsubscribe from your list<\/span><\/a><span style=\"font-weight: 400;\"> whenever they wish. On the one hand, you show people you respect their choice; on the other hand, you let your email list clean itself:)<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">4. Manage bounces<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">I\u2019ve already touched upon the problem of bounces above. They can significantly spoil your email deliverability and sender reputation. So get used to analyzing them as well.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Bounces are commonly divided into two types: soft and hard. Soft bounces happen when an email recipient&#8217;s inbox is full or a server is down. These temporary deliverability problems won&#8217;t cause much trouble \u2013 you can resend emails to such addresses later, and they&#8217;ll be delivered.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Hard bounces, on the contrary, are a pain in the neck. They mean you\u2019re sending emails to invalid email addresses. It\u2019s a signal you should remove these contacts from your list without delay.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">5. Re-engage inactive subscribers<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If your users ignore your emails, it doesn\u2019t necessarily mean they don\u2019t want to hear a word from you. You\u2019re probably sending them the content they\u2019re not interested in at the moment, or your emails are reaching their inbox <\/span><a href=\"https:\/\/snov.io\/blog\/email-frequency-best-practices\/\"><span style=\"font-weight: 400;\">at the wrong time<\/span><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Don&#8217;t hurry up to remove these contacts from your email list. First, send them a <\/span><a href=\"https:\/\/snov.io\/blog\/re-engagement-email\/\"><span style=\"font-weight: 400;\">re-engagement email<\/span><\/a><span style=\"font-weight: 400;\">, where you would try to win back the disengaged by a tempting gift, discount, or VIP content.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A good gesture is to ask inactive subscribers to update their preferences, so they can point out what type of content they&#8217;d like to get from you and how often.\u00a0<\/span><\/p>\n<div class='posts-into__content'>\r\n<div class=\"post\">\r\n    <div class=\"post__img\">\r\n        <img loading=\"lazy\" decoding=\"async\" width=\"320\" height=\"160\" src=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2021\/04\/5wTkBA9naAROEAx0rjQYdUcFynZoj7zIO0BETugU-min-1536x768-1.png\" class=\"attachment-327x160 size-327x160 wp-post-image\" alt=\"How To Win Back Lost Customers With Re-Engagement Emails\" srcset=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2021\/04\/5wTkBA9naAROEAx0rjQYdUcFynZoj7zIO0BETugU-min-1536x768-1.png 1536w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2021\/04\/5wTkBA9naAROEAx0rjQYdUcFynZoj7zIO0BETugU-min-1536x768-1-300x150.png 300w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2021\/04\/5wTkBA9naAROEAx0rjQYdUcFynZoj7zIO0BETugU-min-1536x768-1-1024x512.png 1024w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2021\/04\/5wTkBA9naAROEAx0rjQYdUcFynZoj7zIO0BETugU-min-1536x768-1-768x384.png 768w\" sizes=\"(max-width: 320px) 100vw, 320px\" \/>    <\/div>\r\n    <div class=\"post__content\">\r\n        <p class=\"post__content-title\">\r\n            <a href=\"https:\/\/snov.io\/blog\/re-engagement-email\/\">How To Win Back Lost Customers With Re-Engagement Emails<\/a>\r\n        <\/p>\r\n        <div class=\"post__content-meta\">\r\n            <p class=\"post__content-author\">Darya Jandossova Troncoso<\/p>\r\n            <p class=\"post__content-date\">17\/06\/2026<\/p>        <\/div>\r\n    <\/div>\r\n<\/div>\r\r\n<div class=\"post\">\r\n    <div class=\"post__img\">\r\n        <img loading=\"lazy\" decoding=\"async\" width=\"320\" height=\"160\" src=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2019\/07\/DONE-1-2-min-1536x768-1.png\" class=\"attachment-327x160 size-327x160 wp-post-image\" alt=\"\u00bfCu\u00e1l es la frecuencia del correo electr\u00f3nico ideal?\" srcset=\"https:\/\/snov.io\/blog\/wp-content\/uploads\/2019\/07\/DONE-1-2-min-1536x768-1.png 1536w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2019\/07\/DONE-1-2-min-1536x768-1-300x150.png 300w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2019\/07\/DONE-1-2-min-1536x768-1-1024x512.png 1024w, https:\/\/snov.io\/blog\/wp-content\/uploads\/2019\/07\/DONE-1-2-min-1536x768-1-768x384.png 768w\" sizes=\"(max-width: 320px) 100vw, 320px\" \/>    <\/div>\r\n    <div class=\"post__content\">\r\n        <p class=\"post__content-title\">\r\n            <a href=\"https:\/\/snov.io\/blog\/email-frequency-best-practices\/\">Email Frequency: Best Practices For Email Marketers<\/a>\r\n        <\/p>\r\n        <div class=\"post__content-meta\">\r\n            <p class=\"post__content-author\">Helen Holovach<\/p>\r\n            <p class=\"post__content-date\">2\/09\/2025<\/p>        <\/div>\r\n    <\/div>\r\n<\/div>\r<\/div>\n<h3><span style=\"font-weight: 400;\">6.

For example, one list will include spam markers \u2013 these emails should be removed immediately. One list will embrace inactive contacts you can still try to re-engage with. The third list will be for subscribers who remained inactive even after your impeccable re-engagement efforts \u2013 email list hygiene requires you to remove them as well.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">By doing this, you won\u2019t get lost among your contacts and will filter your list more productively \u2013 by dealing with each group separately.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">7.
