an email tool, an offer, and a consent plan. Start with a tool that stores each address with its consent status. Klaviyo and Mailchimp both do this, and Shopify has its own signup forms. The offer is the reason to join. The consent plan is the rule set for your customers&#39; countries.<\/p>\n<p>Shopify&#39;s help center says to <a href=\"https:\/\/help.shopify.com\/en\/manual\/promoting-marketing\/create-marketing\/customer-contact-information\" target=\"_blank\" rel=\"noopener\">send promotional content only to customers who agreed to receive marketing<\/a>. Treat that as the starting rule on any platform.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Step_2_What_should_you_offer\"><\/span>Step 2: What should you offer?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Offer something your visitors want before they buy. Typical offers are a first-order discount, a giveaway entry, or early access to new products. Klaviyo&#39;s help center suggests <a href=\"https:\/\/help.klaviyo.com\/hc\/en-us\/articles\/360022141751-Grow-Your-Email-List-with-Signup-Forms\" target=\"_blank\" rel=\"noopener\">adding a coupon block to the form&#39;s success step<\/a> to encourage visitors to sign up and then buy.<\/p>\n<p>No source we found measures how much a discount lifts signups, so test it. Margin matters too. A discount that costs more than a new customer is worth will not pay back.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_do_you_limit_a_first-order_discount_to_new_customers\"><\/span>How do you limit a first-order discount to new customers?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Shopify<\/strong><\/p>\n<ol>\n<li>Go to <strong>Discounts<\/strong> and create a discount code.<\/li>\n<li>Under customer eligibility, choose <strong>Customer segments<\/strong>.<\/li>\n<li>Pick a segment built with <code>number_of_orders = 0<\/code>, then click <strong>Add<\/strong>.<\/li>\n<\/ol>\n<p>Shopify&#39;s <a href=\"https:\/\/help.shopify.com\/en\/manual\/discounts\/managing-discount-codes\" target=\"_blank\" rel=\"noopener\">discount management page<\/a> says this targets customers who have not purchased before, identified at checkout by a valid email address or phone number.<\/p>\n<p><strong>WooCommerce<\/strong><\/p>\n<ol>\n<li>Go to <strong>WooCommerce<\/strong> &gt; <strong>Settings<\/strong> &gt; <strong>General<\/strong> and turn on coupons, if they are off.<\/li>\n<li>Go to <strong>Marketing<\/strong> &gt; <strong>Coupons<\/strong> and click <strong>Add new coupon<\/strong>.<\/li>\n<li>Under usage limits, set <strong>Usage limit per user<\/strong> to 1.<\/li>\n<\/ol>\n<p>WooCommerce&#39;s <a href=\"https:\/\/woocommerce.com\/document\/coupon-management\/\" target=\"_blank\" rel=\"noopener\">coupon documentation<\/a> describes this setting.

Klaviyo&#39;s guide says that packing too much into one form <a href=\"https:\/\/help.klaviyo.com\/hc\/en-us\/articles\/360022141751-Grow-Your-Email-List-with-Signup-Forms\" target=\"_blank\" rel=\"noopener\">makes it harder for a visitor to say yes<\/a>. Ask for an email address first. You can ask for more after someone has joined.

Its guide then sets the form to show again only after 5 days if closed, and never after a visitor submits it. It also uses <strong>Don&#39;t show to existing Klaviyo profiles<\/strong>, so current subscribers do not see it.<\/p>\n<p>Our guide to <a href=\"https:\/\/popupsnap.com\/blog\/en\/exit-intent-popups\/\">exit-intent popups<\/a> explains the trigger and its limits on phones.<\/p>\n<p>Keep the popup small.

Your email tool reports the first two. Compare orders from subscribers with your overall results, and with the <a href=\"https:\/\/popupsnap.com\/blog\/en\/average-ecommerce-conversion-rate\/\">average e-commerce conversion rate<\/a> benchmarks for context.<\/p>\n<p>Change one thing at a time, such as the offer or the timing, so you know what moved the numbers. Our guide to how to <a href=\"https:\/\/popupsnap.com\/blog\/en\/reduce-cart-abandonment\/\">reduce cart abandonment<\/a> covers the next email to set up, the reminder for customers who leave without paying.<\/p>\n<p>Klaviyo&#39;s <a href=\"https:\/\/help.klaviyo.com\/hc\/en-us\/articles\/360022141751-Grow-Your-Email-List-with-Signup-Forms\" target=\"_blank\" rel=\"noopener\">sign-up forms guide<\/a> says it turns on CAPTCHA for forms that collect emails. If your list suddenly fills with fake addresses, that is a reason to check your tool&#39;s bot settings.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Frequently_asked_questions\"><\/span>Frequently asked questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"How_many_email_subscribers_do_you_need_to_start\"><\/span>How many email subscribers do you need to start?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>There is no minimum. No source we found sets a threshold, and both Klaviyo and Mailchimp let you send to a small list. Start collecting from day one with one simple form, then judge it by your own signup rate and sales over several weeks. A small list of people who asked to hear from you beats a large one built without consent.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Is_a_first_order_discount_worth_offering\"><\/span>Is a first order discount worth offering?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It depends on your margins, and no source we found measures how much it lifts signups. Klaviyo&#39;s help center suggests adding a coupon block to the form&#39;s success step to encourage signups and purchases. Run it as a test for a few weeks, then compare signups and order value with a period without it.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Do_you_need_double_opt-in\"><\/span>Do you need double opt-in?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Not everywhere, but some countries require it. Shopify&#39;s help center says double opt-in is required by law in some countries and is a good practice anyway, because it builds a list of engaged subscribers. Klaviyo turns it on per list and Mailchimp per audience. If you sell to the EU or the UK, ask a lawyer which setup you need before you send.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Can_you_email_customers_who_bought_but_never_subscribed\"><\/span>Can you email customers who bought but never subscribed?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It depends on where the customer lives. In the UK and the EU, you may email past customers about similar products. You must have offered a simple way to refuse when you collected the address, and in every message since. In the US, the FTC&#39;s CAN-SPAM guide lists no prior consent requirement, but every marketing email needs a working opt-out. A receipt is not marketing, so different rules apply to it.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Check_your_results_against_a_benchmark\"><\/span>Check your results against a benchmark<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>After a few weeks, compare your signup rate and your sales with real numbers.

Klaviyo's help center suggests adding a coupon block to the form's success step to encourage signups and purchases. Run it as a test for a few weeks, then compare signups and order value with a period without it.\"}},{\"@type\":\"Question\",\"name\":\"Do you need double opt-in?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Not everywhere, but some countries require it. Shopify's help center says double opt-in is required by law in some countries and is a good practice anyway, because it builds a list of engaged subscribers. Klaviyo turns it on per list and Mailchimp per audience. If you sell to the EU or the UK, ask a lawyer which setup you need before you send.\"}},{\"@type\":\"Question\",\"name\":\"Can you email customers who bought but never subscribed?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"It depends on where the customer lives. In the UK and the EU, you may email past customers about similar products. You must have offered a simple way to refuse when you collected the address, and in every message since. In the US, the FTC's CAN-SPAM guide lists no prior consent requirement, but every marketing email needs a working opt-out. A receipt is not marketing, so different rules apply to it.\"}}]}<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>To grow an email list, offer something worth an address, show a simple signup form at the right moment, and [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":2821,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[330],"tags":[],"class_list":["post-2833","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ecommerce-marketing"],"_links":{"self":[{"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/posts\/2833","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/comments?post=2833"}],"version-history":[{"count":1,"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/posts\/2833\/revisions"}],"predecessor-version":[{"id":2837,"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/posts\/2833\/revisions\/2837"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/media\/2821"}],"wp:attachment":[{"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/media?parent=2833"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/categories?post=2833"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/popupsnap.com\/blog\/wp-json\/wp\/v2\/tags?post=2833"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
