Email clients will then use that information to <b>add quick unsubscribe links to the messages you send<\/b>.<\/p>\n<p>The concept of list-unsubscribe dates back to 1998 (you can read all about its origins\u00a0<a href=\"https:\/\/www.ietf.org\/rfc\/rfc2369.txt\">here<\/a>) but email clients have adopted it gradually. Very gradually. (For instance, Apple only began processing the list-unsubscribe headers in the Mail app in 2016; Yahoo added it to its mobile apps in 2018.)<\/p>\n<p>List-unsubscribe is a\u00a0<b>user-friendly feature<\/b>: It makes it easier for someone to unsubscribe from a list. There\u2019s no scrolling through and email or hunting for an unsubscribe link. Instead, a person is one immediate click away from getting off an email list.<\/p>\n<p>However, as we\u2019ll discuss,\u00a0<b>it can also be a marketer-friendly feature<\/b>. While it\u00a0<i>does<\/i>\u00a0make it easier for people to get off your list, there\u2019s a real upside nonetheless.<\/p>\n<h3 id=\"How the list-unsubscribe links look in different email

list-unsubscribe options\">The two types of list-unsubscribe options<\/h3>\n<p>There are two ways to send list-unsubscribe headers: A mail-to link and a URL unsubscribe link.<\/p>\n<p>A\u00a0<b>mail-to unsubscribe link<\/b>\u00a0is an email-based list-unsubscribe. With this option, anyone who clicks the email client\u2019s \u201cUnsubscribe\u201d link or button will send an opt-out email to a specified address. The sender\u2019s email software will then unsubscribe that person from marketing emails. This will leave a \u201cpaper trail\u201d of sorts for the user \u2014 they\u2019ll have a copy of that opt-out email in their Sent folder as proof they unsubscribed.<\/p>\n<p>An\u00a0<b>URL unsubscribe link<\/b> is a link to an unsubscribe landing page. This would be similar to clicking the traditional unsubscribe link lower in the email. On that landing page, a user may or may not have to click a button to confirm they\u2019re unsubscribing. (An additional list-unsubscribe header, list-unsubscribe-post, can designate that action.)<\/p>\n<p>As of right now, the four largest email clients (Gmail, Outlook, Yahoo, Apple Mail) support the mail-to method; only Gmail also supports the URL method. The mail-to option is considered safer (the URL in the list-unsubscribe header could be a phishing link), which is why <b id=\"easier\">it\u2019s the preferred option<\/b>.<\/p>\n<p>If you enable list-unsubscribe headers in GMass, we&#8217;ll insert both the mail-to and URL unsubscribe options in your emails.<\/p>\n<p>As of January 2024, we also insert the list-unsubscribe-post header and set it to <code>one-click<\/code>.<\/p>\n<h2>Wait\u2026 You Want Me to Make It Way Easier for People to Unsubscribe? <em>Really?<\/em><\/h2>\n<p>By adding the list-unsubscribe header to your email, you make it easier for people to get off your list.<\/p>\n<p>And that might be, um, the exact opposite of the goal of email marketing.<\/p>\n<p>At least in theory. In practice, there are\u00a0<b>two compelling reasons why you should employ list-unsubscribe<\/b>\u00a0to make the unsubscribing process easier for those who want it.<\/p>\n<h3 id=\"Reason #1: A clean, engaged list is better for business\">Reason #1: A clean, engaged list is better for business<\/h3>\n<p>A big email list is good. An\u00a0<i>engaged<\/i>\u00a0email list is better.<\/p>\n<p>The prevailing theory goes:\u00a0<b>You don\u2019t want anyone on your marketing list who doesn\u2019t want to be there.<\/b>\u00a0That includes people who would never buy from you, will likely never buy from you, and\/or never engage with your emails.<\/p>\n<p>When you have a list packed with disengaged subscribers it\u00a0<b>skews your stats<\/b>. Why is your conversion rate so low? Maybe it\u2019s because a large number of people on your list would never buy under any circumstances. If they all unsubscribed, suddenly your conversion rates would jump \u2014 because now you\u2019re working with active and potentially active customers. And that also allows you to better\u00a0<a href=\"https:\/\/www.gmass.co\/features\/ab-testing-gmail\">A\/B test<\/a>\u00a0and assess what works and what doesn\u2019t work.<\/p>\n<h3 id=\"Reason #2: Easy unsubscribe can help with deliverability\">Reason #2: Easy unsubscribe can help with deliverability<\/h3>\n<p>Let\u2019s say you don\u2019t use list-unsubscribe. Which means there\u2019s no easy access unsubscribe link at the top of your emails.<\/p>\n<p>You know what\u00a0<i>is<\/i>\u00a0easily accessible at the top of every email client? The \u201cmark as spam\u201d button.<\/p>\n<p>If people opt to unsubscribe rather than mark you as spam, that\u2019s good news for your deliverability.\u00a0<b id=\"coldemails\">Unsubscribes won\u2019t hurt your chances of hitting people\u2019s inboxes in the future<\/b>. Spam reports can absolutely hurt those chances.<\/p>\n<p>And half of people\u00a0<a href=\"https:\/\/www.litmus.com\/blog\/why-an-unsubscribe-is-better-than-being-marked-as-spam\/\" target=\"_blank\" rel=\"noopener nofollow\">say<\/a>\u00a0they\u2019ve flagged a marketing email as spam because of a \u201cconfusing or painful\u201d unsubscribe process.<\/p>\n<p>When you make it easy for people to unsubscribe \u2014 as easy as marking as spam \u2014 it\u2019s a smart move for your future deliverability.<\/p>\n<h2>Should You Use List-Unsubscribe in Cold Emails?<\/h2>\n<p>Probably not \u2014 unless you&#8217;re a bulk sender.<\/p>\n<p><b>List-unsubscribe is best if you\u2019re sending promotional\/marketing emails.<\/b>\u00a0That includes things like sales announcements, product announcements, a company newsletter, and other for-profit marketing blasts.<\/p>\n<p>Cold emails do not fall under that umbrella. Cold emails are (in their purest form) highly-targeted, highly-personalized outreach messages. While you may send them at scale using\u00a0<a href=\"https:\/\/www.gmass.co\/gmail-mail-merge\">mail merge<\/a>\u00a0(like, oh I don\u2019t know, a certain beloved cold email app), cold emails are not meant to resemble marketing emails.<\/p>\n<p>Cold emails are (or feel like) one-on-one emails. List-unsubscribe feels less personal. If you want to give people the option to unsubscribe from your cold emails, that\u2019s up to you \u2014 but it\u00a0<b>makes more sense to bake that option into your message<\/b>.<\/p>\n<p>A sentence like, \u201cAnd if you don\u2019t want to get any more emails from me, click here and I\u2019ll take you off my list\u201d is more in line with cold email than a gaudy \u201cUnsubscribe!\u201d button at the top.<\/p>\n<p>List-unsubscribe is also\u00a0<b id=\"enablegmass\">not intended for people sending non-commercial campaigns<\/b>. Non-commercial emails operate under a different set of rules than commercial ones.

And now that I think about it\u2026 the list-unsubscribe link didn\u2019t appear in that Gmail screenshot you used a few paragraphs earlier. Wazzup with that?\u201d<\/p>\n<p>You\u2019re right to question me, and you\u2019re even right to question me using \u201890s slang. And that\u2019s because\u00a0<b>Gmail is quirky (to say the least) about how it displays list-unsubscribe headers<\/b>.<\/p>\n<p>In fact, we are yet to see one of our own list-unsubscribe headers appear in Gmail in our testing.<\/p>\n<p>Google is opaque about why this might be. There are two operating theories.<\/p>\n<h4 id=\"Theory 1: Google is judicious about who does and doesn\u2019t get the easy \u201cUnsubscribe\u201d link\">Theory 1: Google is judicious about who does and doesn\u2019t get the easy \u201cUnsubscribe\u201d link<\/h4>\n<p>According to a 2009\u00a0<a href=\"https:\/\/gmail.googleblog.com\/2009\/07\/unsubscribing-made-easy.html\">post<\/a>\u00a0on Google\u2019s official blog, \u201cyou\u2019ll only see the unsubscribe option for senders that we\u2019re pretty sure are not spammers and will actually honor your unsubscribe request. We\u2019re being pretty conservative about which senders to trust in the beginning; over time, we hope to offer the ability to unsubscribe from more email.\u201d<\/p>\n<p>In other words, they don\u2019t want to give everyone the list-header unsubscribe link automatically \u2014 because\u00a0<b>unscrupulous spammers wouldn\u2019t unsubscribe you<\/b>. Instead, your click on that link would signal your email address is real and active \u2014 meaning they\u2019d just dump even more spam on you.<\/p>\n<p>But they wrote that 13 years ago, which is a lifetime in internet years. So we\u2019ve arrived at another, more likely theory.<\/p>\n<h4 id=\"Theory 2: Google doesn\u2019t display the unsubscribe link on Gmail-to-Gmail links\">Theory 2: Google doesn\u2019t display the unsubscribe link on Gmail-to-Gmail links<\/h4>\n<p>Gmail doesn\u2019t fancy itself an email marketing platform, at least not natively. (Though that might be changing with the advent of\u00a0<a href=\"https:\/\/www.gmass.co\/blog\/gmail-multi-send\/\">Gmail multi-send<\/a>, but that\u2019s a baby step.) That\u2019s why you use third-party options like GMass to run Gmail-based email campaigns.<\/p>\n<p>So\u00a0<b>our lead theory is Gmail ignores the list-unsubscribe headers in Gmail-to-Gmail emails<\/b>. Google doesn\u2019t have any documentation on the topic, but that\u00a0<i>seems<\/i>\u00a0to be the case.<\/p>\n<p>Our experiments validate this theory. We have a high sender reputation with our GMass email list \u2014 one that would certainly hit their threshold for a trustworthy sender who warrants a list-unsubscribe link.<\/p>\n<p>However, even with that list, we don\u2019t get the unsubscribe link in our Gmail-to-Gmail emails.<\/p>\n<p>Note: You\u00a0<i>may<\/i>\u00a0see the link if you send GMass emails through an external SMTP server.<\/p>\n<h4>What this Google quirk means for you<\/h4>\n<p>This means your list-unsubscribe headers may be ignored by Google on emails you send to people with Gmail or Google Workspace accounts.<\/p>\n<p>That\u2019s not ideal, but it\u2019s the reality of sending Gmail-to-Gmail emails. Your best bet:\u00a0<b id=\"tools\">Make sure your traditional unsubscribe link at the end of your email is easy to spot<\/b>\u00a0(not light gray text). That way, at least some (or most) people who want off your list will click that link rather than reporting you as spam.<\/p>\n<h2>List-unsubscribe headers in GMass: The newest tool in your unsubscribe management toolbox<\/h2>\n<p>The list-unsubscribe header is another great way to improve both your unsubscribe management <i>and<\/i>\u00a0deliverability with GMass.<\/p>\n<p>If you aren\u2019t familiar with all of GMass\u2019s\u00a0<a href=\"https:\/\/www.gmass.co\/features\/unsubscribe-management\">unsubscribe management<\/a>\u00a0offerings, list-unsubscribe now joins these tools at your disposal:<\/p>\n<ul>\n<li><strong>Automatic\u00a0<a href=\"https:\/\/www.gmass.co\/features\/unsubscribe-management\">unsubscribe management<\/a>.<\/strong> No need to manually remove addresses from your lists, GMass automatically suppresses future emails to those addresses.<\/li>\n<li><strong>Easy\u00a0<a href=\"https:\/\/www.gmass.co\/blog\/new-gmail-mail-merge-feature-manually-import-or-remove-unsubscribe-addresses\/\">unsubscribe list editing<\/a>.<\/strong> Quickly add, remove, or ignore email addresses on your unsubscribe list.<\/li>\n<li><strong><a href=\"https:\/\/www.gmass.co\/blog\/new-feature-globally-shared-unsubscribes-and-bounces-for-multi-user-google-apps-organizations\/\">Global unsubscribes<\/a>.<\/strong> GMass can check your recipients against the unsubscribe lists for everyone using your same email sending domain and on your team plan \u2014 and automatically suppress your emails to those addresses.<\/li>\n<li><a href=\"https:\/\/www.gmass.co\/blog\/unsubscribe-a-domain\/\"><strong>Unsubscribe an entire domain<\/strong><\/a><strong>.<\/strong> Unsubscribe an entire domain to make sure no more emails go to anyone at that organization.<\/li>\n<\/ul>\n<p>List-unsubscribes also join our best-in-the-world suite of\u00a0<a href=\"https:\/\/www.gmass.co\/features\/deliverability-optimization\">deliverability tools<\/a>, including:<\/p>\n<ul>\n<li><strong>Custom\u00a0<a href=\"https:\/\/www.gmass.co\/blog\/tracking-domain\/\">tracking domains<\/a>.<\/strong> Make sure no one else\u2019s iffy sender reputation has any affect on you.<\/li>\n<li><strong><a href=\"https:\/\/www.gmass.co\/blog\/email-verification-service\/\">Free email verification<\/a>.<\/strong> Verify each email on your list before you send to make sure it\u2019s valid.<\/li>\n<li><strong><a href=\"https:\/\/www.gmass.co\/blog\/spam-solver-tweaks-emails\/\">Spam Solver<\/a>.<\/strong> A unique tool that analyzes an email\u2019s chances of winding up in spam\u2026 suggests tweaks to improve deliverability\u2026 and allows you to test those tweaks before you send your campaign to see if they work.<\/li>\n<li><strong><a href=\"https:\/\/www.gmass.co\/analyze\">Email Analyzer<\/a>.<\/strong> Evaluate any email to see the technical behind-the-scenes details at every step.<\/li>\n<li>And <strong>the\u00a0<a href=\"https:\/\/www.gmass.co\/blog\/introducing-the-email-deliverability-wizard\/\">Email Deliverability Wizard<\/a>.<\/strong> Study the results of campaigns across GMass to see what factors are and are not having an effect on deliverability.<\/li>\n<\/ul>\n<p>If you\u2019re already a GMass user and ready to roll, head to your\u00a0<a href=\"https:\/\/app.gmass.co\/dashboard\">dashboard<\/a>\u00a0to turn on list-unsubscribes.<\/p>\n<p>If you\u2019re not a GMass user, you can\u00a0<b>get started for free<\/b>\u00a0by\u00a0<a href=\"https:\/\/chrome.google.com\/webstore\/detail\/gmass-powerful-mail-merge\/ehomdgjhgmbidokdgicgmdiedadncbgf\">downloading the GMass extension<\/a> from the Chrome Web Store.
