With SMS messages, you can reach recipients quickly and effectively. In LianaMailer, you can send either one-way or two-way SMS messages. SMS sending is done using a dedicated SMS template, which can be found on the Messages page after installation.
One-Way SMS Message
In a one-way SMS message, the recipient cannot reply to the message. The sender can be either a phone number or a sender name.
Using a Sender ID
A Sender ID is the sender name displayed to the recipient when they receive your text message (for example, your company's name).
Due to global regulations designed to prevent SMS scams and falsified sender information, registering your Sender ID has become mandatory in many countries.
In Finland: As of May 2026, unregistered sender names are automatically displayed to recipients as Unknown. From November 2026 onwards, messages from unregistered sender names will be automatically displayed as Spam.
International Deliveries: Because these practices vary by the recipient's country, please make sure to check the guidelines with the local governmental agency overseeing communications.
Liana support can assist you in registering your sender ID. Another option is to register the Sender ID yourself through Traficom (Finland) or corresponding local authority, but remember to notify your selected Sender ID to Liana support as well, so we can ensure message template settings are configured accordingly.
You can read more about Sender IDs on the Traficom website.
| 1 | Give the draft a name. The name is shown on the draft list but it is not visible to the receiver of the message. If no name is given to the message, the name automatically forms from the first few letters of the message. |
| 2 | The sender name is defined in the SMS message template settings. The name must be a Sender ID registered through local authorities e.g. Traficom in Finland; otherwise, the sender name will be displayed as ‘Unknown’. The name must be between 3 and 11 characters long. It may contain only letters (a–z), numbers, and/or underscores. |

Write the message. One message can be max. 160 characters in length. You can also send longer messages when the charged messages are according to the total message count. If you want, you can personalize content with properties. Use then dollar marks, for example $firstname$ If emojis or Unicode characters are used in the message, the maximum character limit for the message is 70 characters. You can add an emoji using the emoji picker in the bottom-right corner. |
| 4 | Message Preview. |
| 5 | In the Summary section, you can see the number of messages per recipient, the number of recipients, and the total number of messages. |
| 1 | Choose the recipient list from the lists that you have uploaded to LianaMailer. |

Enter the phone numbers of recipients in the field. Separate multiple numbers with commas or line breaks. You can enter the phone numbers with the operator code attached (0401234567) or separated with a space (040 1234567) or with a hyphen (040-1234567). LianaMailer automatically adds the country code (+49, for example) to those numbers that don't already have it. If the default country code of the account is the same as in the ones the SMS is sent to, you can enter the country code with the plus sign (+49401234567) or without it (358401234567). If the default country code of the account is different from the ones the SMS is sent to, add a plus sign and the country code (+49401234567) in front of the phone numbers in the address settings. If you don't know the default country code of your account, contact our support. |
| 3 | Enter the time you want the message to be delivered in the Delivery time field and choose the timezone. You don't need to choose a time if you want the message to be delivered immediately. |
| 4 | Save your choices and send the preview message to the number you want. |
| 5 | Send SMS button is activated after sending the preview and you can send the message. |
Two-Way SMS Message
In a two-way SMS message, the recipient can reply to the received message.
Two-way messages use:
- a shared short number
- a customer-specific keyword
The customer-specific keyword is defined by Liana Technologies support during setup.
Important Notes
- A text-based sender name cannot be used as the sender
- The sender must be either a phone number or a short number
- Recipient replies are routed based on the customer-specific keyword
| 1 | Reply number, typically the same as the sender number. As a reminder: a text-based sender name cannot be used here; you must use a phone number or a short code. |
| 2 |
Keyword. This is used in the reply message; in the example below, the keyword is REPLY. In your original message, provide clear instructions on how recipients should reply. For example: ‘Type REPLY followed by your answer, for example: REPLY b.’ The keyword is mandatory and is especially important when using shared short codes, as it ensures that reply messages are routed to the correct account and campaign. |
| 3 | Reply message that will be sent to recipients who responded to the message. |
Keyword
REPLY
Instructions for the Recipient
The message should clearly instruct the recipient to first type the keyword and then their actual response.
Example:
Type REPLY followed by your answer, for example:
REPLY b.
The message content should therefore clearly explain the required reply format.
Confirmation Message for the Recipient
An automatic confirmation message can be enabled in the message template, for example:
Thank you for your order
The confirmation message can be edited or removed entirely.
Viewing Responses
Recipients’ replies are visible in the reports.
The actual response content is shown in the params field.
