Spain issued its first stamp in 1850.<\/p>\n\n<p class=\"wp-block-paragraph\">In 1874 the <strong>Universal Postal Union<\/strong> was created, making it possible to send letters between countries under common rules. More than a century later, email took over as the main form of written communication.<\/p>\n\n<h2 class=\"wp-block-heading\">Advantages and disadvantages of postal mail<\/h2>\n\n<p class=\"wp-block-paragraph\"><strong>Advantages.<\/strong>  It&#8217;s tangible: the recipient can touch it, keep it or stick it on the fridge. It also stands out, because a physical mailbox receives far fewer messages than an inbox. It can have legal value if it&#8217;s sent by registered mail. And it reaches people who don&#8217;t use the internet, such as some older people.<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Disadvantages.<\/strong>  It&#8217;s slower and more expensive than email, every mailing needs paper and printing, and it&#8217;s hard to measure whether it has been read. Also, a mistake can&#8217;t be corrected once it has been sent.<\/p>\n\n<h2 class=\"wp-block-heading\">Postal mail vs. email: the differences<\/h2>\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Aspect<\/th><th>Postal Mail<\/th><th>Email<\/th><\/tr><\/thead><tbody><tr><td>Format<\/td><td>Physical (paper or parcel)<\/td><td>Digital<\/td><\/tr><tr><td>Speed<\/td><td>From one to several days<\/td><td>Seconds<\/td><\/tr><tr><td>Cost per send<\/td><td>Stamp, printing and envelope<\/td><td>Almost zero<\/td><\/tr><tr><td>Measurement<\/td><td>Difficult<\/td><td>Opens, clicks and conversions<\/td><\/tr><tr><td>Personalization<\/td><td>Limited and costly<\/td><td>Easy, with fields and segments<\/td><\/tr><tr><td>Legal value<\/td><td>High for registered mail<\/td><td>Depends on the service<\/td><\/tr><\/tbody><\/table><\/figure>\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/mailrelay.com\/en\/glossary\/electronic-mail\/\" target=\"_blank\" rel=\"noopener\">Email<\/a> inherited its basic concepts from postal mail: the sender, the recipient, the envelope (the subject line) and even the <a href=\"https:\/\/mailrelay.com\/en\/glossary\/business-letter\/\" target=\"_blank\" rel=\"noopener\">business letter<\/a>, which today is almost always sent by email.<\/p>\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1536\" height=\"1024\" src=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/postal-mail-vs-email.jpg\" alt=\"Infographic comparing postal mail and email in format, speed, cost per send, measurement and legal value\" class=\"wp-image-104755\" srcset=\"https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/postal-mail-vs-email.jpg 1536w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/postal-mail-vs-email-300x200.jpg 300w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/postal-mail-vs-email-1024x683.jpg 1024w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/postal-mail-vs-email-768x512.jpg 768w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/postal-mail-vs-email-110x73.jpg 110w, https:\/\/mailrelay.com\/wp-content\/uploads\/2026\/10\/postal-mail-vs-email-60x40.jpg 60w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><\/figure>\n\n<h2 class=\"wp-block-heading\">Postal mail in marketing<\/h2>\n\n<p class=\"wp-block-paragraph\">Many companies combine the two channels. <a href=\"https:\/\/mailrelay.com\/en\/glossary\/direct-marketing\/\" target=\"_blank\" rel=\"noopener\">Direct marketing<\/a> by postal mail works well for catalogs, exclusive invitations or gifts for good customers, and email lets you keep the conversation going at a much lower cost.<\/p>\n\n<p class=\"wp-block-paragraph\">Some ways to combine them:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Send a printed catalog<\/strong> and, a few days later, an email with a discount code to buy online.<\/li>\n\n\n\n<li><strong>Ask for the email address in your physical mailings<\/strong> with a QR code that leads to your subscription form.<\/li>\n\n\n\n<li><strong>Save paper for special occasions<\/strong>, such as anniversaries or VIP customers, and use email for regular communication.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">This combination of channels is the foundation of <a href=\"https:\/\/mailrelay.com\/en\/glossary\/omnichannel\/\" target=\"_blank\" rel=\"noopener\">omnichannel<\/a> marketing.<\/p>\n\n<h2 class=\"wp-block-heading\">How Mailrelay helps you<\/h2>\n\n<p class=\"wp-block-paragraph\">With Mailrelay you bring the best of postal mail to email: personalized messages with each recipient&#8217;s name, templates with your brand identity and statistics to know who has read your message.<\/p>\n\n<p class=\"wp-block-paragraph\">The free account includes up to 80,000 emails a month and 20,000 contacts, with human support in English on all plans.<\/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>Combine paper with email<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stay in touch with your customers between postal mailings, and find out who opens your messages.
