Frequently asked questions.


How is my data secured?

Is Esendex GDPR compliant?

Esendex is already certified to ISO 27001 standards, so to comply with GDPR we improved upon existing processes rather requiring than a full re-design.

The steps we took included conducting a data lifecycle audit, an investigation of the technical and organisational measures we currently take to protect personal data, and deploying “privacy by design” in all of our product development. Find out more about our GDPR compliance.

How quickly will my messages be sent?

Very quickly; the Esendex messaging system is monitored both internally and externally and then measured against availability, performance, service incidents and planned maintenance to ensure a consistently excellent performance.

As part of our SLA, we commit to 90% of your messages being processed within 5 seconds and 95% within 20 seconds. Our performance consistently exceeds our service promise, providing you with the best possible service.

Should I provide an opt-out option?

It is good practice to ensure that you are using opted in data when sending marketing messages otherwise you will be spamming your recipients. It is also important for you to provide an easy opt-out solution when sending SMS to contacts.

How much will it cost me to send SMS?

The more you buy the cheaper it gets, it’s as simple as that. Our prices start from as little as 2.3p and we will even throw in a free trial so you can try before you buy…it doesn’t get much better than that!

Will I be tied into a contract?

We give you the flexibility to send messages your way, so whether you’re a frequent sender or new to SMS, there’s an option suit you. We offer the choice of either contract or pay as you go. With a contract you’ll be sending regular volumes and will therefore benefit from our very best price – if you’re unsure of volumes, have a one-off campaign or are just starting out, pay as you go could be the option for you.
