Your customers are constantly on their phones. Your message should be too.
The simplest way for your team to send SMS
No new software. No new logins. No training required. Your team uses the email client they already know — and SMS happens automatically.
No programming needed
If you can send an email, you can send SMS. No API keys, no developer, no technical setup — just compose and send from your existing email client.
Anyone in your team can use it
No app to install, no separate login to manage. Every authorised team member sends SMS from the email account they already use every day.
Send to an entire group with one email
Name a group in the subject line and your message goes to hundreds or thousands of contacts simultaneously — all from a single email.
Privacy-friendly — no phone numbers needed
Restricted users can send to named groups without ever seeing individual mobile numbers. Perfect for privacy-sensitive environments like healthcare or HR.
Replies land in your inbox
Two-way messaging built in. When a recipient replies to your SMS, it comes back to your email — no separate inbox to monitor.
Works from any email client
Outlook, Gmail, Apple Mail, web-based email, automated systems — if it can send an email, it can trigger MessageWorks Email-to-SMS.
Automatic opt-out compliance
Anyone who replies STOP is automatically removed from future sends. No manual list management required.
Secure domain authentication
Only emails from your verified domain and authorised sender addresses can trigger SMS. No spoofing, no accidental sends.
Before You Start — Prerequisites for Email Users
Before any email trigger will work, two things must be in place on your account. Both are set up once and work permanently from then on.
Your email address must be registered as an Authorised Sender. This confirms your emails are legitimate. Set up under Senders & Users → Authorised Senders.
Alternatively, your account can be set to allow any email from your verified domain — contact us to enable this.
For larger teams, verify your company domain once (e.g. yourcompany.com.au) so that every employee can send without being individually listed as an Authorised Sender. Set up under Senders & Users → Verified Domains.
Five powerful email addresses — endless possibilities
All trigger addresses follow the same format: [trigger]@e2s.messageworks.au. Send to any of these five addresses to trigger different SMS actions.
