Each country has its own restriction on the type of content that messages sent contain. <strong>If that content does not meet certain established standards, your messages could be restricted.<\/strong><\/p>\n<p>Another point to highlight is that the telecommunications operating companies validate the content of the SMS links through a process that <strong>can take between 24 and 48 hours, before effective delivery.<\/strong><\/p>\n<p>Next, we explain what you must take into account so that your campaigns are successful.<\/p>\n<h2>Tips and restrictions<\/h2>\n<p>There are some points that you must take into account depending on the country of the recipient of your message and some general good practices that will help you maximize the effectiveness of your shipments.<\/p>\n<p>&nbsp;<\/p>\n<h3>Always ask permission<\/h3>\n<p>Never send an SMS to a client who has expressly not agreed to receive your messages. To accomplish this, make sure <strong>all of your contacts have opted-in to your contact list<\/strong>.<\/p>\n<p>What is opt-in? We call this the process by which a user explicitly gives us permission to send him messages. If you want to learn more about what opt-in is and how to configure it, you can visit our article \u201c<a href=\"https:\/\/help.fromdoppler.com\/en\/differences-between-simple-and-doble-opt-in?utm_source=direct\">Single and Double Opt-in Forms: What are they and how can i set them up<\/a>\u201d<\/p>\n<p>This guarantees your consent and prevents us from becoming spammers. Also, make sure you don&#8217;t put up unnecessary obstacles if your contacts want to opt out, that is, unsubscribe from your list.<\/p>\n<p>&nbsp;<\/p>\n<p><b>Ensure the deliverability of your messages<\/b><\/p>\n<p><span style=\"font-weight: 400;\">We recommend that when creating the content of your SMS, you use customizable shorteners that allow you to add your own verified domain, which leads to the correct and reliable website. Why do we advise this? Because those messages that are sent with shortened links of the <\/span><b>bit.ly <\/b><span style=\"font-weight: 400;\">type will not be delivered correctly for security and phishing reasons.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In this instance, security experts and the corresponding telephone companies will review the contents of the SMS to detect and avoid malicious links or inappropriate content for users.<\/span><\/p>\n<h3><\/h3>\n<h3>Check the schedule<\/h3>\n<p>Some countries may restrict your message depending on the time you send it.<\/p>\n<p>Be sure to <strong>send your SMS during the day<\/strong> and avoid night hours. Besides, beyond the restrictions of each country, your contacts will thank you for not waking them up in the early morning \ud83d\ude09<\/p>\n<p>&nbsp;<\/p>\n<h3><\/h3>\n<h3>Keep the rules in mind<\/h3>\n<p><strong>Some regions have specific requirements for SMS campaigns<\/strong>. If you violate the regulations of the places where your customers reside, it is very likely that your contacts will not receive your messages.<\/p>\n<p>Therefore, we have detailed some important points for you to keep in mind when sending text messages to the following countries:<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Argentina<\/strong><br \/>\n&#x274c;\u200b Political content is restricted<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Brazil<\/strong><\/p>\n<p>&#x2714;&#xfe0f; Requires opt-in to receive marketing content or promotions<\/p>\n<p>&#x2714;&#xfe0f; URLs have to be approved by the sending provider<\/p>\n<p>&#x2714;&#xfe0f; The option to unsubscribe from SMS must be provided<\/p>\n<p>&#x274c; Content about religion, politics, abortion, or that infringes on third party intellectual property is restricted<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Chile<\/strong><br \/>\n&#x274c;\u200b Content about alcohol, drugs, or politics is restricted<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Colombia<\/strong><br \/>\n&#x2714;&#xfe0f;\u200b Requires opt-in to receive political content.
