Using double opt-in rather than single opt-in works much more effectively. Implementing double opt-in builds and sets up the email marketing tone and trust for the people who want to know about you. This also helps you maintain email compliance, stating that you should get consent from the email recipient.<\/p>\n\n\n\n<p>MailBluster\u2019s double opt-in feature makes it easy to send a confirmation email to subscribers. You can use the double opt-in feature of MailBluster to verify email addresses and subscribe to your brand.

People who sign up on this day will be counted as the opt-in list.<\/p>\n\n\n\n<h4><strong><span style=\"margin-right:10px;\" class=\"badge-round\">2<\/span>Offer emails<\/strong><\/h4>\n\n\n\n<p>Send offer emails in the fall, summer, and spring to provide exclusive offers on special occasions.

Also, welcome emails are the opt-in emails that trigger when a user subscribes and let them know more about the brand, products, and the service they provide.&nbsp;<\/p>\n\n\n\n<p>Look at the welcome email opt-in example &#8211;<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"363\" height=\"584\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/Welcome-email.jpg\" alt=\"Welcome email from MailBluster\" class=\"wp-image-11366\" srcset=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/Welcome-email.jpg 363w, https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/Welcome-email-186x300.jpg 186w\" sizes=\"(max-width: 363px) 85vw, 363px\" \/><\/figure><\/div>\n\n\n\n<p><br>This welcome email comes from MailBluster. The email, as usual, starts with the brand name and welcome message. Also, it encourages the user to go to the next steps and try different services MailBluster provides. This eventually leads users to the prospective and potential buyers at the same time.<\/p>\n\n\n\n<h4><strong><span style=\"margin-right:10px;\" class=\"badge-round\">4<\/span>Opt-in forms<\/strong><\/h4>\n\n\n\n<p><a href=\"https:\/\/mailbluster.com\/blog\/mailbluster-forms\" target=\"_blank\" rel=\"noreferrer noopener\">Opt-in forms<\/a> are simply an instant subscription form that gives users the opportunity to provide their email, name, or any other information to register or subscribe to a specific area or the entire website. Users willingly subscribe or sign up using opt-in forms to receive regular updates of blog or website services. MailBluster includes 2 types of opt-in forms you can use &#8211;<\/p>\n\n\n\n<ul><li>Inline forms<\/li><li>Pop-up forms<\/li><\/ul>\n\n\n\n<p>See the opt-in forms example &#8211;&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"335\" height=\"571\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/2-1.jpg\" alt=\"Opt-in form by MailBluster\" class=\"wp-image-11369\" srcset=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/2-1.jpg 335w, https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/2-1-176x300.jpg 176w\" sizes=\"(max-width: 335px) 85vw, 335px\" \/><\/figure><\/div>\n\n\n\n<p><br>This is a pop-up form from MailBluster. Pop-up forms appear when you visit any website within 2-3 seconds. You can see the form contains a discount offer flashing on sale with a timer\/ countdown on top. <br>Also, First name, Gender, and Email address, T&amp;Cs checking fields are there with the Subscribe button at the end. All of these fields collect lead information and let you subscribe to the service or product.&nbsp;<\/p>\n\n\n\n<h4><strong><span style=\"margin-right:10px;\" class=\"badge-round\">5<\/span>Single vs. double opt-in&nbsp;<\/strong><\/h4>\n\n\n\n<p><strong>Single opt-in<\/strong> is a simple email sign-up form without an opt-in option, meaning users directly sign up in this way. Whereas, <strong>double opt-in<\/strong> is a sign-up form that collects email, name, or any other information, including the user&#8217;s consent, with a confirmation link sent to the subscriber. <\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"645\" height=\"635\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/Double-opt-in.jpg\" alt=\"Double opt-in example template from MailBluster\" class=\"wp-image-11407\" srcset=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/Double-opt-in.jpg 645w, https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/Double-opt-in-300x295.jpg 300w\" sizes=\"(max-width: 709px) 85vw, (max-width: 909px) 67vw, (max-width: 984px) 61vw, (max-width: 1362px) 45vw, 600px\" \/><\/figure><\/div>\n\n\n\n<p><br>You can easily build an opt-in list with both methods. But <a href=\"https:\/\/mailbluster.com\/blog\/double-opt-in\" target=\"_blank\" rel=\"noreferrer noopener\">double opt-in<\/a> is the better option here, as it collects information with user consent.&nbsp;<\/p>\n\n\n\n<h4><strong><span style=\"margin-right:10px;\" class=\"badge-round\">6<\/span>Warm-up email&nbsp;<\/strong><\/h4>\n\n\n\n<p>Warm-up email refers to the increasing number of emails sent from a new email account, meaning starting from a low number of emails and gradually increasing numbers to improve the sender\u2019s reputation. <br>You can start sending emails from your newly created email address to your lead list and gradually increase the volume to build trust with users. This also increases the chance of sending emails directly to the recipient&#8217;s inbox rather than the spam folder.<\/p>\n\n\n\n<h4><strong><span style=\"margin-right:10px;\" class=\"badge-round\">7<\/span>Opt-in email template<\/strong><\/h4>\n\n\n\n<p>Opt-in email template is a visual email subscription copy and contains the <a href=\"https:\/\/mailbluster.com\/blog\/email-subject-lines-importance-and-tips\" target=\"_blank\" rel=\"noreferrer noopener\">subject line<\/a>, email message, and call-to-action or CTA button that drives users to their product or service. Opt-in email templates are generally the confirmation or verification emails that reach users&#8217; inboxes.&nbsp;<\/p>\n\n\n\n<p>Take a look at this one &#8211;<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"479\" height=\"744\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/4.jpg\" alt=\"Opt-in email by AWS \" class=\"wp-image-11367\" srcset=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/4.jpg 479w, https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/4-193x300.jpg 193w\" sizes=\"(max-width: 479px) 85vw, 479px\" \/><\/figure><\/div>\n\n\n\n<p><br>This is a verification email that reaches the user&#8217;s inbox, stating that an existing account has tried to sign in and that AWS needs to verify the real user. Also, additional account creation and related resources are available to introduce users to more materials.<\/p>\n\n\n\n<h4><strong><span style=\"margin-right:10px;\" class=\"badge-round\">8<\/span>Referral programs<\/strong><\/h4>\n\n\n\n<p>Referral programs are offers from the brand that give users an incentive to invite others via a referral link, and both parties receive an incentive for the referral. Referral is a very effective way to get more users to sign up and grow your opt-in leads.&nbsp;<\/p>\n\n\n\n<p>Here is an example of an opt-in email referral program &#8211;<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" width=\"549\" height=\"612\" src=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/MailBluster-affiliate-referral1.jpg\" alt=\"MailBluster's referral email\" class=\"wp-image-11405\" srcset=\"https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/MailBluster-affiliate-referral1.jpg 549w, https:\/\/mailbluster.com\/blog\/wp-content\/uploads\/2025\/10\/MailBluster-affiliate-referral1-269x300.jpg 269w\" sizes=\"(max-width: 549px) 85vw, 549px\" \/><\/figure><\/div>\n\n\n\n<p><br>The above image shows how MailBluster\u2019s affiliate referral link is shared with the affiliate user, and it also reminds them to share it. Bringing users through the referral link opens the opportunity to earn and grow your email list simultaneously.&nbsp;<\/p>\n\n\n\n<h4><strong><span style=\"margin-right:10px;\" class=\"badge-round\">9<\/span>Create events<\/strong><\/h4>\n\n\n\n<p>Creating and organizing events, meetups, or conferences increases the likelihood of collecting email addresses from attendees. Keep records of attendees and collect email details with their consent to send product or service-related emails.<\/p>\n\n\n\n<h4><strong><span style=\"margin-right:10px;\" class=\"badge-round\">10<\/span>Cold email list<\/strong><\/h4>\n\n\n\n<p>Cold email list is a list of unsolicited emails that introduce the service or product to those who are not familiar with your brand.
