Introducing bulk SMS for businesses
Bulk text messaging via SMS is one of the most effective ways to communicate with your customers, employees, and contacts. SMS marketing yields an average open rate of 98%, nearly three times higher than email. Response rates can be as low as 90 seconds, compared to 90 minutes from traditional channels.
SMS vs Email
Although it’s hard to put a figure on it, industry research suggests that more than 100 marketing emails can land in someone’s inbox daily. Businesses often experience low open rates and engagement because the subject line or content isn’t interesting or relevant, or they lack the tools to send messages and optimise their campaigns.
Email is still a powerful communication tool. However, mass text messages can provide clear and hyper-targeted information to the right people at exactly the right time. You don’t have to compete for attention in cluttered inboxes, nor worry that timely messages will be missed because someone doesn’t have internet access or a smartphone.
50% of all emails are spam, which means our inboxes are more cluttered than ever.
55% of people prefer SMS messaging for notifications like appointment reminders over email.
SMS message tends to be concise and engaging, so click-through rates are typically much higher.
Millennials receive an average of 67 text messages per day, making it easier to convey your message.
How does a bulk SMS service work?
Bulk SMS works similarly to email marketing. You log onto your bulk SMS Gateway and segment your intended audience according to who you want to target. The Gateway, a type of software, connects your business messaging application with the mobile network, enabling you to reach people on their smart or feature phones.
Creating short, personalised messages is faster and easier than writing a long email newsletter – and as long as it’s clear, concise and engaging, it’s a powerful way to communicate. Bulk SMS software allows you to schedule messages to maximise responses and automatically send confirmation details and reminders when someone makes a booking on another platform.

FAQs about our bulk messaging solutions
What is bulk SMS?
As the name suggests, bulk SMS is simply when a business or other organisation sends out text messages to mobile devices on a mass scale. Text messages are typically used in promotional campaigns, appointment or reservation reminders, and for security, such as resetting passwords or providing a one-time password (OTP). You may also refer to bulk SMS as bulk messaging, mass text messaging, mass online SMS, or application-to-person (A2P) messaging.
How does bulk text messaging work?
For bulk messaging, you can simply upload or import data from your database to your bulk SMS gateway, which saves you time and reduces the risk of errors compared to manual data entry. You can send the same message or personalised ones, to individual or multiple phone numbers.
We connect to all mobile networks, and you can segment customers to send relevant and personalised bulk text messages no matter how big the group is. Using our SMS API, you can send text messages in bulk to mobile phones directly from our CRM system.

How do you make sure your mass text campaigns are legally compliant?
As the bulk SMS sender, you ensure that communications adhere to data protection laws.
Esendex is ISO27001 certified, meaning your customer data is safe and protected to the highest standard. We have taken steps to improve our processes, including a data lifecycle audit and a ‘privacy by design’ principle in our products.
Our SMS platform features the latest standard security protocols and firewalls. We utilise access controls, antivirus software, secure equipment, encryption, regular backups, and disaster recovery procedures. Our platform is continually monitored. When sending a marketing SMS, ensure that you have obtained permission from your customers, and it’s essential to offer an opt-out option, which is a legal requirement.
Find out more about SMS Laws and read our privacy policy.
Can I activate two-way messaging with my contact lists?
Yes, you can. With Esendex, you have the option of sending one-way or two-way messages to imported contact lists. To enable two-way conversations, your account must use a Virtual Mobile Number (VMN) or a Short Code (rather than an alphanumeric Sender ID). A dedicated number or short code will allow contacts to reply to your messages and have their responses received by your account.
