Two laws apply to sending advertising SMS in Spain:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>LSSI (Article 21).<\/strong>  You need the recipient&#8217;s prior, express consent. The exception is your own customer, if you write to them about products similar to the ones they have already bought. Every message must offer a simple, free way to unsubscribe.<\/li>\n\n\n\n<li><strong>GDPR.<\/strong>  It regulates how you collect, store and use phone numbers. You must state what you use them for and be able to prove you have permission.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Before acquiring new contacts, also check the <a href=\"https:\/\/mailrelay.com\/en\/glossary\/robinson-list\/\" target=\"_blank\" rel=\"noopener\">Robinson List<\/a>, where people who don&#8217;t want to receive advertising sign up. Sending without permission is <a href=\"https:\/\/mailrelay.com\/en\/glossary\/spam\/\" target=\"_blank\" rel=\"noopener\">spam<\/a>, by SMS too.<\/p>\n\n<h2 class=\"wp-block-heading\">Advantages and limits of SMS marketing<\/h2>\n\n<p class=\"wp-block-paragraph\">SMS works very well for urgent messages, but it isn&#8217;t right for everything:<\/p>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Advantages<\/th><th>Limits<\/th><\/tr><\/thead><tbody><tr><td>It arrives instantly and is read within minutes<\/td><td>Only 160 characters per message<\/td><\/tr><tr><td>It doesn&#8217;t need an internet connection or an app<\/td><td>Every SMS has a cost<\/td><\/tr><tr><td>Any phone can receive it<\/td><td>It doesn&#8217;t support images (that&#8217;s what <a href=\"https:\/\/mailrelay.com\/en\/glossary\/mms\/\" target=\"_blank\" rel=\"noopener\">MMS<\/a> is for)<\/td><\/tr><tr><td>It&#8217;s easy to measure<\/td><td>If you overdo it, customers unsubscribe<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\">The key is to send sparingly and with a clear reason: an offer with a deadline, a reminder or a notice the customer is expecting.<\/p>\n\n<h2 class=\"wp-block-heading\">SMS, email or WhatsApp: which to use<\/h2>\n\n<p class=\"wp-block-paragraph\">Each channel has its role. The best approach is to combine them:<\/p>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Channel<\/th><th>Best for<\/th><th>Limits<\/th><\/tr><\/thead><tbody><tr><td>SMS<\/td><td>Urgent notices, reminders and flash sales<\/td><td>160 characters and a cost per message<\/td><\/tr><tr><td>Email<\/td><td>Newsletters, catalogs and long-form content<\/td><td>It can take longer to be read<\/td><\/tr><tr><td>WhatsApp<\/td><td>Conversations and customer service<\/td><td>The user must have the app and agree to receive messages<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\">For example, send the full promotion by email and, a few hours before it ends, an SMS reminder.<\/p>\n\n<h2 class=\"wp-block-heading\">How much does SMS marketing cost?<\/h2>\n\n<p class=\"wp-block-paragraph\">You pay per message sent. With Mailrelay, an SMS to Spain costs between \u20ac0.0345 and \u20ac0.0357 depending on the package, excluding VAT:<\/p>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Package<\/th><th>Price<\/th><th>Price per SMS<\/th><\/tr><\/thead><tbody><tr><td>350 SMS<\/td><td>\u20ac12.50<\/td><td>\u20ac0.0357<\/td><\/tr><tr><td>7,500 SMS<\/td><td>\u20ac260<\/td><td>\u20ac0.0347<\/td><\/tr><tr><td>50,000 SMS<\/td><td>\u20ac1,725<\/td><td>\u20ac0.0345<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\">Credits last one year and there is no commitment. A long message counts as several SMS. The price varies by country: you can find it on the <a href=\"https:\/\/mailrelay.com\/en\/pricing\/sms\/\" target=\"_blank\" rel=\"noopener\">SMS pricing<\/a> page.<\/p>\n\n<h2 class=\"wp-block-heading\">How Mailrelay helps with your SMS marketing<\/h2>\n\n<p class=\"wp-block-paragraph\">With Mailrelay you send your SMS from the same dashboard as your email campaigns. You can paste a list of numbers or use the ones from your contacts.<\/p>\n\n<p class=\"wp-block-paragraph\">The editor warns you if the message is too long and splits it automatically. You also choose the sender name and see in the statistics how many SMS were delivered.<\/p>\n\n<div class=\"wp-block-group has-very-light-gray-background-color has-background\" style=\"border-radius:8px;padding-top:24px;padding-right:28px;padding-bottom:24px;padding-left:28px\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Send SMS to your customers with Mailrelay<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Packages from 350 SMS, no commitment, with support via chat, ticket and phone.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button is-style-mailrelay-primary-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/mailrelay.com\/en\/signup\/?utm_medium=cta&amp;utm_campaign=sms-marketing\">Try Mailrelay for free<\/a><\/div>\n<\/div>\n<\/div><\/div>\n\n<h2 class=\"wp-block-heading\">Frequently asked questions about SMS marketing<\/h2>\n\n<p class=\"wp-block-paragraph\">These are the most common questions before launching an SMS campaign.<\/p>\n\n<h3 class=\"wp-block-heading\">What is an SMS campaign?<\/h3>\n\n<p class=\"wp-block-paragraph\">It&#8217;s a batch of text messages sent to a group of customers with a specific goal, such as selling, reminding them of an appointment or notifying them about an order.<\/p>\n\n<h3 class=\"wp-block-heading\">How many characters does an SMS have?<\/h3>\n\n<p class=\"wp-block-paragraph\">160 characters with the standard alphabet and 70 if you include emojis or special characters. If the text is longer, it is split into several SMS and each one is charged.<\/p>\n\n<h3 class=\"wp-block-heading\">Can you send advertising SMS without permission?<\/h3>\n\n<p class=\"wp-block-paragraph\">No. In Spain, the LSSI requires prior consent, unless the person is already your customer and you write to them about similar products. They must always be able to unsubscribe.<\/p>\n\n<h2 class=\"wp-block-heading\">Related terms<\/h2>\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/sms\/\" target=\"_blank\" rel=\"noreferrer noopener\">SMS<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/bulk-sms\/\" target=\"_blank\" rel=\"noreferrer noopener\">Bulk SMS<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/sms-sending-platform\/\" target=\"_blank\" rel=\"noreferrer noopener\">SMS sending platform<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/transactional-sms\/\" target=\"_blank\" rel=\"noreferrer noopener\">Transactional SMS<\/a><\/li>\n<\/ul>\n","protected":false},"template":"","class_list":["post-84986","glossary","type-glossary","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
