Figure 4.  Schematic of Internet based email-to-sms relaying.


The technical bit.

For those that aren't interested in technical details click here for a flash animation which demonstrates the basic concept.

Messages are sent (figure 4) from your PC or application (1), via email across the internet (2), through our firewalls and to our email servers. Our email servers are based in 3 different physical locations to ensure reliability and redundancy. If mail cannot be processed by one of the servers, your mail will be routed to a different server for processing. The message is then parsed and inserted into a secure database cluster (the database is backed up every hour and stored behind 2 seperate firewall systems). The messages are then extracted by our messaging engine (5) and relayed to the relevant network and on to the handset.
Delivery receipts simply follow the same path, but in reverse.

the service

The email to sms service works in two ways, 'pre defined' and 'open sending'. Using the service in 'open sending' mode allows you to send emails from one or more specified email addresses and have them relayed as an SMS text message to any mobile number.

A quick summary - using email to sms you can ::
  • set up a single email address which goes to a single phone number ("pre defined sending")

  • set up an "allowed sender" email address which can email any phone ("open sending")

  • set up an "allowed sender"/address combination that can send an email to a mobile distribution list

  • set up a single email address which goes to a single phone and also copies the mail to your own email address


Below is more information on these options..

email to sms 'open sending'

Using the service in open sending mode allows you to have emails sent from one or more specified email addresses relayed to any mobile number. The destination number is specified in the email address and the originating email address is validated and matched to your account

How does it work?

From your sms2email account you would setup one or more email addresses (ie the email address of the sender) for which our system will allow email to sms relaying through your account. Once an email address is setup you can then send emails to...

<any mobile number>@text.sms2email.com (eg. 07740123456@text.sms2email.com)

The 'from address' for the email would be matched to your account and the first 160 characters of the email would be relayed on as an SMS text message to the specified mobile number. Your account will be charged 1 credit per text message sent for most locations. Some destinations are charged at higher rates (click here to view destinations and charges).

email to sms 'pre defined'

Using the service in pre defined mode allows you to setup email addresses which you can give to friends and colleagues. Emails sent to this address will be relayed to a pre defined mobile number, allowing you to receive emails send to this address as SMS text messages on your mobile phone.

How does it work?

From your sms2email account you would setup an 'alias' (subject to availability) at the sms2email.com domain, for example the alias 'fred' would give you the email address 'fred@sms2email.com'. Alongside this alias you will assign the mobile phone number you would like the message to be sent to. When an email is sent to this address, the first 160 characters of the message will be relayed as an SMS to your mobile phone. Your account will be charged 1 credit per text message sent for most locations. Some destinations are charged at higher rates (see click here. to view destinations and charges.

Can I have more than one address?

You can set up multiple aliases at the sms2email.com domain. For example you would be able to setup an address and mobile number for each member of staff in your company making it simple to contact them while out of the office.
