If the function is enabled, email sent to the email address:

PHONE_NUMBER@IP_ADDRESS_OF_SMSEAGLE
will be converted to SMS message.

where:
PHONE_NUMBER
 – is a destination phone number
IP_ADDRESS_OF_SMSEAGLE – is the IP address of your device.
The text of the email is the text of the SMS message (optionally you can append email subject at the beginning of SMS message).

Example: email message sent to the address: 123456789@192.168.0.101 will be converted to SMS message and delivered to phone number 123456789.

Send to username / group

This feature is available in software version 2.5 and higher. Email sent to the email address:

NAME_IN_PHONEBOOK@IP_ADDRESS_OF_SMSEAGLE
will be converted to SMS message and will be sent to a user or users group from SMSEagle’s phonebook.

where:
NAME_IN_PHONEBOOK
 – is a username or group name (must be a public group) from SMSEagle’s phonebook
IP_ADDRESS_OF_SMSEAGLE – is the IP address of your device.
The text of the email is the text of the SMS message (optionally you can append email subject at the beginning of SMS message).

Example: email message sent to the address: db-admins@192.168.0.101 will be converted to SMS message and delivered to all members of db-admin group. The db-admin group must be defined in your SMSEagle phonebook.

Using FQDN in email address

It is also possible to use Fully Qualified Domain Name in an email address sent to SMSEagle box (eg.: 123456789@mydomain.com). Please refer to our FAQ article: How do I configure Email2SMS plugin to accept FQDN email addresses for more details.

Send to LDAP / contacts / groups

If your company uses LDAP (Active Directory or OpenLDAP) for contacts management, you may use LDAP Contacts or Groups to send email to SMS text message.

Example: email message sent to the address: myldap-admins1@192.168.0.101 will be converted to SMS message and delivered to all members of myldap-admins1 group. The myldap-admins1 group must be defined in your LDAP directory and LDAP plugin must be configured on your SMSEagle device.

Configuration

For your convenience “Email To SMS” feature allows you to add several rules that define what happens with incoming email.

Adding/editing rules

For each rule a user can define:

  • If forwarding should always be sent or only form specified senders/when email contains
  • Specify the incoming email address
  • Specify the text of the message
  • *For multi-modem devices users can also define from which modem the SMS is sent.*

Authentication

If you want to use user authentication, set ‘What to do with email subject’ setting to ‘Use for authentication’. If user authentication is enabled, provide in a subject of an email your login and password in the following form: login=john&pass=doe OR provide API access token in the following form: access_token=toke

Voice calls

SMS message that was converted from email can be optionally followed by a wake-up call or text-to-speech call. This can be enabled in the rule definition. The feature requires a device with active Voice-Call add-on.

What is an SMS address?

An SMS address is an email-like format (e.g., 1234567890@vtext.com) used to send a text message via email through a mobile carrier’s gateway. This method depends on the recipient’s carrier and is being phased out or limited by many providers. SMSEagle doesn’t rely on this — it sends SMS directly using SIM cards.

It’s the mobile network the recipient uses (like T-Mobile, Vodafone, or Orange). If you send texts through email-to-SMS gateways, you need to know the carrier to format the address correctly. With SMSEagle, you don’t need the carrier info — just the phone number.

Two-way messaging means the recipient can reply to your SMS and their response comes back to your system. SMSEagle fully supports this using SIM cards. Just keep in mind that if you use a custom alphanumeric sender ID, replies won’t work — because it’s not a real number.

SMSEagle can automatically forward incoming SMS messages to email. You set this up in the SMS to Email section. You can use your own SMTP server or let SMSEagle send the messages directly using its built-in client.

Send an email to the SMSEagle’s email address (set in the device). It will convert the message into an SMS and deliver it via SIM — no carrier gateway needed. Make sure you whitelist the sender’s email in the settings.

A hardware SMS gateway (like SMSEagle) is a physical device with SIM cards that sends and receives SMS directly through mobile networks. It doesn’t rely on external APIs or internet-based services.

Benefits include:

  • Works even when internet goes down
  • No third-party services or fees per message (only your SIM plan)
  • Local control and better privacy
  • Two-way SMS support

No. SMS is sent via SIM cards and mobile networks. You only need internet access for using features like email-to-SMS, web interface access, API communication, or firmware updates.

That depends on the model:

  • NXS-9700-4G models come with 1 or 2 modems (1 or 2 SIM cards).

Only the MHD-8100-4G model supports 8 modems/SIMs — great for high-volume use, load balancing, or using multiple mobile networks.
