ENWhy don’t my contacts receive the SMS I sent
If you notice that your SMS shows Delivered, but your recipients never received them, it is possible that the delivery providers have restricted your content.
If this is your case, we will help you understand why it happens and how to solve it 🙂
What are shipping providers
From Doppler, we have different telecommunications operating companies in each country, as providers to send SMS to your contacts.
Each of the countries to which you can send SMS from Doppler have its own restrictions on the type of content that is allowed to be sent and in the event that these regulations are not respected, your messages could be restricted.
For this reason, we tell you what you must take into account so that your campaigns are successful.
Tips and restrictions
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.
Always ask permission
Never send an SMS to a client who has expressly not agreed to receive your messages. To accomplish this, make sure all of your contacts have opted-in to your contact list.
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 “Single and Double Opt-in Forms: What are they and how can i set them up”
This guarantees your consent and prevents us from becoming spammers. Also, make sure you don’t put up unnecessary obstacles if your contacts want to opt out, that is, unsubscribe from your list.
Check the schedule
Some countries may restrict your message depending on the time you send it.
Be sure to send your SMS during the day 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 😉
Keep the rules in mind
Some regions have specific requirements for SMS campaigns. If you violate the regulations of the places where your customers reside, it is very likely that your contacts will not receive your messages.
