Understanding what portion of your subscriber base uses Apple Mail today\u2014and how many are opted into MPP\u2014is your first step to forming how to best respond.<\/p>\n<p>Email Analytics makes it easy to see how your specific email program is impacted by MPP, and a handful of <a rel=\"noopener\" href=\"https:\/\/www.litmus.com\/blog\/a-snapshot-of-the-email-service-provider-landscape\/\" target=\"_blank\" rel=\"noopener\">email service providers<\/a> (ESPs) have started to introduce data filtering to account for false email opens, too.<\/p>\n<h2>Email marketers are trying new tactics<\/h2>\n<p>Since MPP makes it impossible to know whether a subscriber is really opening the email (or not!), measuring true engagement with content intended to capture \u201csigns of life\u201d from a subscriber has become more important than ever.\u00a0Polls, gamified experiences, links, and a simple \u201cthumbs up\u201d are all great ways to encourage engagement.<\/p>\n<p>We\u2019ve also started to see some email marketers come right out and ask subscribers to click if they\u2019re truly interested in remaining on the list.<\/p>\n<img decoding=\"async\" class=\"alignnone size-full\" src=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Screen-Shot-2022-06-06-at-2.14.25-PM.png\" width=\"1368\" height=\"376\" \/>\n<p>&nbsp;<\/p>\n<img decoding=\"async\" class=\"alignnone size-full wp-image-48951\" src=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Screen-Shot-2022-06-06-at-2.18.14-PM.png\" alt=\"email example that asks subscribers to click anywhere in email to measure engagement in light of MPP\" width=\"1828\" height=\"168\" srcset=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Screen-Shot-2022-06-06-at-2.18.14-PM.png 1828w, https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Screen-Shot-2022-06-06-at-2.18.14-PM-300x28.png 300w, https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Screen-Shot-2022-06-06-at-2.18.14-PM-1024x94.png 1024w, https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Screen-Shot-2022-06-06-at-2.18.14-PM-768x71.png 768w, https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Screen-Shot-2022-06-06-at-2.18.14-PM-1536x141.png 1536w, https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Screen-Shot-2022-06-06-at-2.18.14-PM-1800x165.png 1800w, https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Screen-Shot-2022-06-06-at-2.18.14-PM-700x64.png 700w\" sizes=\"(max-width: 1828px) 100vw, 1828px\" \/>\n  \t\t\t<\/div>\n  \t\t<\/div>\n  \t<\/div>\n  <\/div>\n<\/div>\n\n\n\n\n\t<div id=\"simple-text-block-block_629e4550dda2d\" class=\"block-simple-text-block alignfull \" style=\"background-color:\">\n  <div class=\"container\">\n  \t<div class=\"row\">\n  \t\t<div class=\"col\">\n  \t\t\t<div class=\"copy\">\n  \t\t\t\t<h2>Work with (not against) MPP<\/h2>\n<p>Some Litmus users have come to the Litmus Customer Support team with questions related to the activity MPP <i>really <\/i>masks. For example, we\u2019ve heard questions about whether MPP might offer &#8220;tells&#8221; that reveal when open rates reflect actual human interaction. Spoiler alert: there are none. That\u2019s why we group all of them under the Apple privacy-impacted opens group. And remember, MPP is a privacy measure that subscribers opt into by choice. We as email marketers have a duty to respect those wishes.<\/p>\n<p>Email Analytics users have also asked us whether MPP opens can still collect individual-level data, such as contact IDs or custom parameters. That answer is yes!<\/p>\n<p>With <a rel=\"noopener\" target=\"_blank\" href=\"https:\/\/help.litmus.com\/article\/136-what-is-a-merge-tag\" target=\"_blank\" rel=\"noopener\">merge tags<\/a> and our custom parameters field, you can collect additional data about your opens. Your custom parameter can be a campaign code, web analytics code, or another merge field from your messaging platform or ESP.<\/p>\n<h2>You may want to reimagine A\/B subject line testing<\/h2>\n<p>Now that we know some MPP-impacted opens aren\u2019t reliable, what\u2019s the fate of the A\/B <a rel=\"noopener\" href=\"https:\/\/www.litmus.com\/blog\/subject-line-tests-and-tips\/\" target=\"_blank\" rel=\"noopener\">subject line test<\/a>? This a commonly asked question from many of our Litmus users.<\/p>\n<p>Cynthia Price, Senior Vice President of Marketing at Litmus, says one option is to find a segment that isn&#8217;t impacted and use it as a proxy\u2014but acknowledges that type of <a rel=\"noopener\" href=\"https:\/\/www.litmus.com\/blog\/combining-segmentation-and-personalization\/\" target=\"_blank\" rel=\"noopener\">segmentation<\/a> isn\u2019t possible for everyone.<\/p>\n<p>To overcome the challenge, Jaina Mistry, Senior Email Marketing Manager at Litmus, recommends a new approach: Rethink the goal of your subject line entirely. \u201cRather than just trying to get an open, you want subscribers\/readers to take action. In that case, measuring click-through rate or conversion rate when A\/B testing subject lines is an option.\u201d<\/p>\n<p>To make that an effective test, Mistry says email marketers will need to invest real effort into making both the subject line and preview text actionable. In cases where this approach isn\u2019t appropriate, it may simply be time to stop relying on A\/B testing subject lines and open rates as a cut-and-dry measure of success.<\/p>\n<p>Ready to get up to speed on all the latest happenings related to MPP? <a rel=\"noopener\" target=\"_blank\" href=\"https:\/\/page.litmus.com\/mpp-and-email-marketing.html\" target=\"_blank\" rel=\"noopener\">Grab your guide now<\/a>!<\/p>\n<div class=\"cta\">\n<table style=\"background-color: #f2f3f6\">\n<tbody>\n<tr>\n<td class=\"block-1\" style=\"padding: 20px 10px 20px 20px\"><img decoding=\"async\" class=\"alignnone size-full wp-image-48913\" src=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Mail-Privacy-Protection-and-Email-Marketing.jpg\" alt=\"image of Litmus' Mail Privacy Protection and Email marketing guide\" width=\"720\" height=\"576\" srcset=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Mail-Privacy-Protection-and-Email-Marketing.jpg 720w, https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Mail-Privacy-Protection-and-Email-Marketing-300x240.jpg 300w, https:\/\/www.litmus.com\/wp-content\/uploads\/2022\/06\/Mail-Privacy-Protection-and-Email-Marketing-700x560.jpg 700w\" sizes=\"(max-width: 720px) 100vw, 720px\" \/><\/td>\n<td class=\"block-2\" style=\"padding: 20px 20px 20px 10px\"><strong>Mail Privacy Protection (MPP) and Email Marketing: Your 5 Step Response Guide<\/strong><\/p>\n<p class=\"zero\">Get up to speed on what MPP means for your email strategy, including how to evaluate its impacts on your audience so far, campaign strategies to pivot in light of MPP, and ways to re-evaluate email performance<\/p>\n<p class=\"zero\"><a class=\"btn medium orange button\" rel=\"noopener\" target=\"_blank\" href=\"https:\/\/page.litmus.com\/mpp-and-email-marketing.html\" target=\"_blank\" rel=\"noopener noreferrer\">GET THE GUIDE<\/a><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n  \t\t\t<\/div>\n  \t\t<\/div>\n  \t<\/div>\n  <\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":48959,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"tags":[110,10267,10274,86,9954,10247],"blog_category":[10305],"class_list":["post-48945","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","tag-apple","tag-campaign-performance","tag-email-analytics","tag-engagement","tag-mail-privacy-protection","tag-performance-metrics","blog_category-email-marketing-performance"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.5 (Yoast SEO v27.7) -
