Echo's Frequently Asked Questions.

How is my data secured?


At Esendex, we pride ourselves on our security and reliability and have taken a number of measures to protect all data to the highest standard.
We are ISO27001 certified – an independent security standard setting a framework for establishing, operating, reviewing and improving Information Security Management. This ensures all customer data is protected to the highest standard, so you can rest assured that all your details are safe with us.

How many characters can I use in a message?


A single message can contain up to 160 characters. However, if you're struggling to fit everything in, we offer the option to send up to 612 characters by combining 4 message parts into one message. This would cost the same as sending 4 messages.

How can I see if messages have been delivered?


When you log into your account you can see real-time message statuses, this makes it easier than ever to keep track of your messages.

Can I have multiple users on a single account?


Absolutely, and we advise you to do this, rather than share passwords. You can have as many users as you need on each account; each user will have a separate username and password for maximum security. The username of the sender of a message will be visible, allowing you to track who has been sending each message.

How many messages can I send?


You can send as many messages as needed, so no matter how big or small your business is, our platform can handle it.
