All with a custom alphanumeric sender Given the amount of spam and unwanted messages people receive every day, it’s no surprise that they often ignore messages from unknown numbers.
And when those messages come from international philippines mobile number example numbers, the chances of the recipient opening them are especially low. In countries where alphanumeric senders are supported, you can use them to dramatically increase your open rates. Additionally, for countries where alphanumeric sender registration is available, you can also improve message delivery by reducing operator filtering of A2P (Application-to-Person) traffic, and manage fluctuations in telecommunications logic, local regulations, and operator-specific rules.
When you register your alphanumeric sender, your messages and number are approved by local authorities to establish the legitimacy of your messages and pass them through operator firewalls. And because you can send your SMS with a custom sender name, such as your company name, your recipients will always know who is sending them.
This way, you reinforce your brand every time you send a message with your company name. You can use alphanumeric senders only to send one-way messages, meaning recipients cannot reply to them.
Because of this limitation, we recommend using alphanumeric senders for one-way outbound messaging use cases, such as one-time passwords and notifications.
If you want users to respond, simply include contact information in your messages. Additionally, since users cannot respond directly, we recommend including opt-out instructions in the body of the message to ensure compliance with CTIA and other regulatory guidelines, especially for promotional messages.
