When your email address is registered to an account with us, you can easily use the services directly from your email, entirely without installations or plugins. It works with all kinds of email and webmail.
You address the email to us in a special way, and we automatically convert the message to an SMS and send it to the recipient. It is as easy to send to one as to many.
What does the sender of the SMS look like? When you send an SMS from your phone, your number is always displayed as the sender. When you send via us, you have more options, you can, for instance let the recipient respond to the message so that it comes directly back to your email. Read more about this under Settings. Keep in mind that an address book has its own settings for how the sender is displayed. Read more about the Address Book here.
You do not have to enter a subject when you send an SMS, but if you do, we will add it to the top of the message, keep in mind that it is included in the total number of characters.
Send easy to one or many
Enter the recipient’s mobile number in the “To-field” and end with @esms.nu. Just like when you send regular emails, it is easy to add more recipients.
Write your message and click Send, and the recipients will have your message within seconds!
If you often send to the same people, you can save them among your regular email contacts, they work like regular email addresses.
Send to an address book
If you have saved an address book in the Toolbox on the web, you can easily send messages to the address book directly from your email, you do not have to log in to the web every time. Simply enter the address book’s unique email address in the “To-field” and send your message as usual.
The address book’s unique email address can be found under Resources in the Toolbox, where you can also see who is registered as a writer and authorized to send to the address book’s members. If it is your address book, you are usually also a writer.
Keep in mind that the address book has its own settings for what messages look like when they are sent to the recipient.
Send to many with broadcast
If you have many recipients, it may be easier to add their number, followed by .sign, directly in the email, then you address the mail to firstname.lastname@example.org and after the message you enter the code word DistriButionList (spelled exactly that way) followed by the recipients numbers.
If you enter a semicolon (;) after the number, you can also add the recipient’s name.The name is then visible in your logs and it may be easier to follow up if any message can’t be delivered.
How to calculate the SMS size?
A normal text message contains 160 characters using the GSM 7 bit alphabet
This is a limitation in the format used to send text messages.
To be able to send longer messages, we must divide the message into 153 characters and send them as individual text messages. 7 characters for each part is used to let the recipient phone know how to assemble the parts into, seemingly, one long text message for display.
This means that if your text is longer than 160 characters, it will cost more than sending one SMS.
Sending to an Address Book
Each Address Book has it´s own settings that might add text to the message and that also must be counted in the total number of characters sent. The Toolbox editor cannot count these, it only counts the characters in the message box.
If you have any text in "SMS Header" it will be added first in your message.
If "SMS Unsubscribe Footer" is activated, the system will also add some characters in the end of your message, informing the recipient how to unsubscribe. Depending on the type of originator your message has, different texts will be added, ranging from 30 to 40 characters.
If you are unsure how long your message will be, we recommend that you send a test to yourself first. Please contact us and we can help you see how many parts your message was divided into.
Regular textformat - GSM7
Characterset GSM 03.38 is the most common for SMS and creates GSM 7 bit alphabet.
According to wikipedia the following characters are available:
Then there is some characters that will make your message longer without converting it to Unicode, according to Wikipedia it´s the following:
When does it turn into Unicode?
When the message contains characters outside the GSM 7 bit alphabet, the entire message is turned into Unicode.
This covers several different character tables, the most common is GSM 8 bit.
A message coded in GSM 8 bit can be only 70 characters per SMS, as each character takes up more space than GSM 7 bit does. If the message is longer than 70 characters, the message will have to be divided into several parts containing 67 characters each. The biggest GSM 8 bit coded message you can send with a text message would be 1072 characters, and it would be divided into 16 SMS.
In GSM 8 bit you will for example find the lower case greek letters and many latin characters (for example: š, ž, –, ´ and “).
Emojis belongs to GSM 16 bit, taking up even more characters per character.
